Tray Distillation Unit (TDU)

Operating Manual



1 Background Continuous distillation or more precisely continuous fractional distillation is one of the most important unit operations Billions of dollars are invested in equipment to perform this process Distillation equipment typically accounts for some 80 of the capital investment in an oil refinery The Tray Distillation Unit (TDU) is a small pilot unit designed to demonstrate the process of fractionation

2 Description of Facilities The TDU apparatus is a modified version of the Model 9079 Scott Tray Distillation Unit consisting primarily of a small distillation column with six (6) sieve trays an electrically heated reboiler and a total condenser TDU is instrumented sufficiently to demonstrate continuous fractional distillation in the partial separation of methanol from a mixture of methanol isopropanol and water Apart from understanding the basic theory behind the unit operation of distillation sufficiently to study it in an experimental setting it will be necessary to familiarize oneself with the TDU system by studying the detailed schematic in Figure 1 and then tracing out the lines identifying the control and shut-off valves pumps and other instruments The Laboratory Instructor can provide a lsquotour of the unitrsquo to facilitate this An electronic power transducer on the electrically fired reboiler immersion heater indicates directly in watts the reboiler heat duty1 Municipal water provides cooling in the total condenser as measured by the rotameter mounted near the right end of the condenser Electrical heaters provide preheat for the feed and reflux streams Any tray can serve as the feed tray through use of quick connections Liquid sample points allow sampling of feed distillate bottoms and individual tray liquids An Emerson DeltaV control system provides measurement and control of temperature level flow rate and reboiler power Rotameters provide backup measurement capability for distillate reflux and feed flow rates A dedicated Hewlett-Packard gas chromatograph allows offline analysis of feed tray liquid overhead and bottoms product The time required to move from a cold startup to achievement of steady state is typically 90 to 120 minutes From that point moving to a new set of conditions requiring compositional change may take roughly 60 minutes for column compositions to line out to steady-state values2

1 The voltmeter and ammeter mounted near the center of the unit panel display measurements needed to calculate any additional heat supplied by the electrically fired reboiler strip heaters These strip heaters are normally used during heatup of TDU but may not be needed during experimental runs depending on conditions desired Consult with your instructor regarding their use 2 In Fall 2009 just short of 50 lbs of glass marbles were placed in the reboiler vessel substantially reducing its liquid holdup and thus reducing the overall column capacity Reduced capacity has resulted in quicker line out to steady-state conditions and faster column dynamics in general

3 Basic Operation of TDU from DeltaV Operate Run

Logging Into and Using the DeltaV(TM) System Access to the DeltaV system is made possible in virtual fashion from a VLAB virtual machine reachable from any of the thin-clients in the control room proper Though there are several DeltaV virtual machines available the CHE-UOLAB-DV2 virtual machine is reserved and set up for access to the packed bed reactor unit Accessing this virtual machine is done through Windowrsquos Remote Desktop Connection feature visible from the Start menu To access one of the DeltaV virtual machines after logging into a VLAB virtual machine follow the steps outlined here

Click the Start button then click the Remote Desktop Connection item on the popup

menu

On the Remote Desktop Connection popup that appears enter the name of the virtual

DeltaV station desired [For the Polymerization Reactor (POLY use che-uolab-dv1 or

che-uolab-dv4 For the Tray Distillation Unit (TDU) use che-uolab-dv2 For the Packed

Bed Reactor (CAT) use che-uolab-dv3]

Click the Options button and then click the Local Resources tab Under Local devices

and resources click the Morehellip button Expand the Drives area if necessary Check the

apps drive box and the box for Removable Disk (if you have installed a jump drive and

want it to be accessible from the DeltaV virtual machine) Click OK Click Connect

At the Do you trust this remote connection menu click Connect

On the Windows Security popup that appears click Use another account icon

In the two fields that appear next type administrator in the Use name field and deltav

in the Password field Click OK

A Remote Desktop Connection warning menu appears next Click Yes

A DeltaV Logon menu appears next Type deltav in the Password field Click OK

A Flexlock menu window appears next Click the Windows Desktop button Minimize

this menu window

At this point the DeltaV virtualized station of choice is up and operating From here access the DeltaV Operate Run program and the Process History View program (and Control Studio from che-uolab-dv1) from the Windows Start menu One should also be able to access the apps drive and a connected jump drive (if installed) from Windows Explorer on the DeltaV virtual machine

To start up the control schematic navigate to Start gt DeltaV gt Operator gt

DeltaV Operate Run The UOLAB_Overview display should come up Click on

the hot-linked photo of the Tray Distillation Unit Doing this should automatically



open the TDU_Main display as shown in Figure 2 below If a dialog box appears

indicating an error click Skip All on the dialog box

Turning on Pumps Flows and Heaters To turn reflux feed and bottoms pumps from the on (red) and off (green) position click the appropriate ss (startupshutdown) button in the PUMPS section of the

display Similarly to turn the feed reflux and reboiler heaters to and from the on (red) or off (green) position click the appropriate oo (onoff) button in the (PRE)HEATER

section of the picture The condenser cooling water is turned to and from the on or off position by clicking



the ONOFF button in the COOLING WATER section of the display The button shows

green in the off position and red in the on position The use of green and red here are helpful When these devices are all in their non-running state they show green in the running state they show red

Using Controller Interlocks All the pumps and heaters have interlocks that will allow turning these pumps and heaters on only if certain conditions exist The following interlocks operate on the TDU

Engaging the feed and reflux heaters require the flow of some feed or reflux

Engaging the reboiler heater requires the reboiler temperature to be below

120C

Engaging the reflux pump requires sufficient level in the reflux drum

Engaging the feed pump requires adequate head space in reboiler and

Engaging the bottoms pump requires a minimum level in the reboiler Each of these has an override button with the heading ovr over it for use in case of

some emergency or other unique operating situation Checking the override box disables the interlocks Overriding these interlocks may require justification to the Laboratory Instructor

Changing Controller Parameters from Controller Faceplates On the operations schematic the appearance of a small icon ndash identifiable by a gray box with three vertical lines ndash signals the presence of an automatic controller To the left of each controller icon are the process value (PV the measurement) in yellow

the setpoint (SP) in white and the output (OP) in cyan To change a parameter on a

controller click on this icon to bring up a faceplate From the faceplate change controller mode by clicking on the desired mode button on the left side of the faceplate Manually changing the controller output (OP) is only possible in MANual mode To

change the controller output click on the MANual value field at the top of the

faceplate and enter a new value Click-dragging the large cyan pointer ndash present only when the controller is in MANual mode ndash to a new position also changes the

output of the controller The smaller cyan pointers are output limit indicators and are not changeable from the controller faceplate



When the mode is not MAN the controller uses the process value (PV) setpoint

(SP) and tuning constants to calculate a new output (OP) every processing pass

Manually changing the controller setpoint (SP) is only possible in AUTO mode To

change the controller setpoint click on the setpoint value field on the right side of the faceplate and enter a new value Click-dragging the large white pointer ndash present ONLY when the controller is in AUTO ndash to a new position also changes the setpoint

of the controller The smaller white pointers setpoint limit indicators and cannot be changed from the controller faceplate

Using Cascade Control Sometimes controllers are stand-alone (eg the feed flow rate controller) and sometimes they are in a cascade structure (eg the reflux level controller is cascaded to the reflux flow rate controller) Cascade connections are indicated by dotted lines on the schematic in Figure 1 The upper controller in a cascade is called the PRIMARY and the lower controller is called the SECONDARY Secondary controllers require an additional mode so the computer system will know when to close the cascade (ie put the cascade structure fully on control) In Emersonrsquos DeltaV System this mode is called CAS When the mode of the primary is

AUTO and the mode of the secondary is CAS the cascade is closed and the primary

sends its OP to the secondary controllerrsquos SP When the mode of the secondary is

AUTO the human operator is responsible for changing the SP to control the process

Accessing Additional Controller Details Across the bottom of the faceplate are six icons that call up other displays with more details about this controller The two most useful ones for this experiment are the first one from the left which provides access to controller parameters and the second one from the right which calls up the historical trend for this controller

Accessing Real-time Process History To start up the real-time process history view at any time simply navigate to Start

gt DeltaV gt Operator gt Process History View and then open TDU_Main

(if it does not open automatically) Chart scales can be compressed or expanded by clicking those buttons on the menu bar Scales can be shifted up or down by click dragging on the scale of interest



4 Historical Data Access Using DeltaV Continuous

Historian A continuous historical record of all relevant temperatures flows and levels is kept by the DeltaV system on its hard disk(s) Selected portions of these data can be imported into an Excel spreadsheet for analysis This spreadsheet must be saved to a flash drive or a personal directory if it is to be used on any other personal computer than a dedicated DeltaV workstation as files stored on the DeltaV network are not accessible from the general LSU network To import data from DeltaV history to Excel Emerson has provided an Excel add-in called the DeltaV Continuous Historian It appears under the Add-Ins

menu in Excel 2007 when this program is opened on a DeltaV workstation Any process variable that is enabled in History Collection can be imported Most of

these variables are collected every 10 seconds 30 seconds or 1 minute so it doesnt make sense to try to read the data any faster Though the menu features of the DeltaV Continuous Historian can be used

for their intended purpose requesting an ad hoc retrieval of data for more than one or two tags is tedious and time-consuming To avoid this labor an Excel 2007 template file is available for TDU data retrieval This template is preloaded to request ALL the historically trended TDU tags The only information that the user must supply is the starting date and time the ending date and time and the time interval between data values To import data open Excel 2010 on the DeltaV workstation and follow these steps

1 Put Excel calculations in Manual mode before opening the template or attempting to change the starting and ending dates

2 Open the data retrieval template file for TDU It is located on the Desktop in the DeltaV_Excel_Data_Collector_Files folder under the name TDU_Data_Retrievalxlsx

3 Enter (or modify) the starting date and time for the data of interest as mmddyyyy hhmm into cell A4

For example data starting August 5th 2008 at 9AM would be entered as 852008 900

4 Enter (or modify) the ending date and time for the data of interest as

mmddyyyy hhmm into cell A6

For example data ending August 5th 2008 at 3PM would be entered as



852008 300PM or 852008 1500

5 Enter (or modify) the desired time interval between data values

For example to request data values every 10 seconds enter =rdquo10secondsrdquo

into cell A8 For data values every 2 minutes enter =rdquo2minutesrdquo into cell A8

Any value of seconds minutes or hours may be used but some values make more sense than others Using values faster than the fastest data originally collected makes no sense So values below 10 seconds only make sense if data collection on some variables has been set to time intervals below 10 seconds Data will be interpolated where there are no values A maximum of 2161 readings (2160 intervals) are available in any one data retrieval operation This will allow the retrieval of 6 hours of 10 second data 36 hours of 1 minute data or any other combination that results in 2160 (or fewer) intervals If more data are required two separate requests must be made and concatenated manually Of course if only a few tags are needed one can bypass the use of the template and retrieve data ad hoc using DeltaV features

6 After entering the last of these user inputs click the Add-Ins menu tab click the DeltaV drop-down tab roll over the Continuous Historian option and select Refresh All values in the spreadsheet should update signaling successful retrieval of data

7 To save these results these data must be turned into static values as follows Select the entire worksheet (by clicking in the upper left hand corner of the worksheet adjacent to the A1 cell Copy this selection (eg ctrl v) Select the

2nd worksheet tab Using Paste Values paste the values copied from the

Data Collection tab into the 2nd worksheet These values are now static and

will be available even when the spreadsheet is relocated to another computer The values in the first tab can be deleted at this point IF the file will not be used to retrieve additional data from the DeltaV

8 Save this file under a different name onto the desktop of the DeltaV virtual machine To get this file to your apps drive for example simply right-click the file and click Copy Then minimize the RDC machine access the desired destination from the original client desktop and Save to the appropriate folderlocation (Remember that calculation mode for that file is Manual)

9 The units for the data are the same as in DeltaV If the word shutdown appears

instead then either

History collection was not enabled for that variable or

No history collection because the system was shut down or

No history collection because the variable did not change more than its deviation value set in history collection (ie nothings changing)



5 Some Safety Considerations Never click the ovr (override) button for the pumps or the heaters unless certain

that an override is justified Be prepared to justify this to a Laboratory Instructor

All unused sample material must be returned to the feed tank

Check all temperatures periodically No temperature should exceed 80C

Although the bottoms pump can run dry for short periods it should be shut off if a no flow condition is noted

Make sure the condenser water is flowing whenever the experiment is running This is the only active method for removing heat from the column

6 Startup and Operating Procedures and General Guidance

Modes of Operation The two most common modes of operation for a continuous distillation column are total reflux mode and finite reflux mode Total reflux mode facilitates some aspects of column performance measurement and simpler column startup In total reflux mode all overhead material from the column is condensed and returned to the column as reflux Therefore total reflux mode is an important performance mode since this maximum reflux condition produces the best possible component separation at otherwise comparable conditions Additionally there is no feed addition or product withdrawal from the column in total reflux mode Without the distraction of managing these external streams reflux flow and reflux drum level control can be more easily established Finite reflux mode is a more practical mode for operation of a continuous distillation column for the obvious reason that continuous streams of products result Feed continuously introduced to the column is fractionated or split into (at least) two products an overhead stream and a bottoms stream Though finite reflux mode does not produce the maximum possible component separation accomplished in total reflux mode it does result in a commercially viable situation with product streams

Ensuring the Achievement of Steady State As mentioned previously the TDU column requires some time to approach steady state An indication that steady state has been achieved will be that all temperatures levels and flow rates in the column remain constant However the most conclusive confirmation that steady state has been achieved is constant product composition determined by offline GC analysis of liquid samples



Conditions at Startup All controllers should be in MANual at the start of a run The condenser cooling water

is turned to and from the on or off position by clicking the ONOFF button in the

COOLING WATER section of the display The button shows green in the off position

and red in the on position

Safety Item

Always keep the cooling water on when running this experiment This is the only means of removing heat from the column through condensation of overhead product

Starting Up TDU in Total Reflux Mode In total reflux mode once the composition of the initial feed charge has been set only one independently selectable variable remains reboiler heat duty The reflux rate that ultimately results from a steady state total reflux mode operation is forced This inevitability suggests an obvious strategy for starting up in total reflux mode fix the reboiler heat duty and adjust reflux rate to hold constant level in the reflux drum To this end the following method3 is suggested for establishing steady state total reflux mode operation in the TDU

Supply cooling water to the TDU ndash Turn on the cooling water The condenser cooling water is turned to and from the on or off position by clicking the ONOFF button in the COOLING WATER section of the display The button

shows green in the off position and red in the on position

(Condenser water flow rate is controlled by a rotameter on the front panel of the TDU Unless performing experiments that have as their intent the manipulation of this rate operate this rotameter at full-scale open)

Ensure that the starting reboiler liquid level is appropriate ndash Normally this level has already been established prior to each dayrsquos run(s) Starting levels from 85 to 95 provide reasonable operational capabilities after some of this material is displaced to the column proper and the reflux drum during startup Experimental program may also suggest the choice of level here There is a low level alarm at 30 to ensure that the liquid level does not fall below the level of the heaters If the level is too low prior to startup add feed before starting experiments if too high prior to startup use the bottoms pump to withdraw material and return it to the feed tank (Though it is fine to add material AFTER startup withdrawing material AFTER startup in total reflux experiments will change the composition of the material in the unit)

3 When confidence with TDU operations is obtained one may adjust this method to speed up start-up



Supply heat to the TDU by establishing the desired reboiler heat duty ndash Turn on the reboiler heater (and the strip heaters via the switch at the top right of the unit) put the reboiler temperature controller (H004) in MAN give it an

output (OP) of at least 60 or other value required by the experimental

program4 and wait for overhead material to condense and the reflux drum to start filling

(Acceptable TDU performance is obtained with reboiler heat duty produced by reboiler heater output (OP) in the range from 60 or more with the use of

additional heat from the reboiler strip heaters Without the strip heaters higher reboiler heater output (OP) is required for best performance Consult

with your instructor regarding this service if you have questions)

Establish a low but sustainable reflux flow rate ndash When the reflux drum level reaches 50 put the reflux flow rate controller (F002) in AUTO give it a

setpoint (SP) of 20 and turn on the reflux pump As soon as the reflux

begins to flow (signified by the yellow bar on the controller faceplate) start decreasing the setpoint (SP) in steps of a percent or so every few seconds

until the reflux flow rate is 12-13 At reflux rates much lower than this the turbine meter may stop reading5

Establish reflux preheating ndash The reflux preheater power is turned on with the reboiler heater power However one still needs to put the reflux preheat

controller (H002) in AUTO give it a setpoint of 65C or other suitable value

(Use this heater unless the requirements of a specific experimental program suggest otherwise)

Find and sustain the correct total reflux flow rate ndash Wait for the reflux drum level to reach at least 50 Manually adjust the reflux rate by changing the setpoint (SP) on the reflux flow controller as necessary to provide a constant

reflux drum level of between 25 and 75 in the reflux drum Again experimental program requirements may suggest a more appropriate reflux drum level Depending on the nature of the experiment it may be possible ndash even advisable ndash to use the Reflux Drum Level Reflux Flow Rate cascade control system to automatically adjust the reflux rate to keep the drum level constant

Identify the existence of steady state ndash When all flows levels temperatures and compositions are lined out steady state has been achieved

4 Getting the unit to operating temperature more quickly can be accomplished by firing this heater (and perhaps the strip heaters) at 100 of output until tray temperatures have nearly peaked at which point heater output can be set to the level required by the experimental program Indeed it may be possible to fire this heater at 100 of output until the reflux drum level has approached the midway point In any case ultimate lineout to steady state will be necessary prior to collection of quality data 5 Successful operations in manual mode have been observed with the reflux flow rate controller setpoint as low as 8 to 9 No guarantees however



Conducting Operations in Finite Reflux Mode Establishing finite reflux mode operations in TDU is more complicated than establishing total reflux mode operations Three external flows must be established column feed distillate product and bottoms product In finite reflux mode after the composition rate and entry point of the feed stream have been set two independently selectable variables remain one bottoms-related variable and one overhead-related variable This premise suggests a strategy for establishing finite reflux mode6 establish total reflux mode operation at the desired reboiler heater duty ndash bottoms-related variable begin feed addition adjust the bottoms product rate to maintain reboiler constant adjust the reflux and distillate rates to meet the overhead-related variable requirements and to maintain constant reflux drum level attain steady state To move from total reflux mode to finite reflux mode

Establish total reflux operation ndash Start the column up in total reflux mode at the reboiler duty desired for the finite reflux operations establishing a steady reflux drum level but do not wait for the column to come to steady state otherwise

Select desired feed tray ndash Move the flexible feed line to the feed input point of choice One can choose any of the six sieve trays or the reboiler as a feed input point To move the flexible feed line from one location to another simply pull back on the red-colored locking ring and then pull the feed line out from the current location letting the locking ring slide forward At this point simply push the feed line into the new location If the new location is a sieve tray use your gloved hand to support the back of the glass column when inserting the flexible feed line

This operation is best done before starting up the unit but can be done safely as described above even if liquid is in the column and even after feed if flowing through the feed line The quick disconnect locking ring assembly prevents liquid from flowing out of the feed line when disconnected even if the feed pump is on

Establish feed to the column ndash Put the feed flow rate controller (F001) in

AUTO give it a setpoint (SP) corresponding to the desired feed rate turn on

the feed pump turn on the feed preheater put the feed preheat controller

(H001) in AUTO and give it a setpoint (SP) of 65C or other temperature

consistent with the experimental program

6 When confidence with TDU operations is obtained one can modify this procedure to speed up start-up



(Use this heater unless the experimental programs suggests otherwise)

Establish a trial reflux rate ndash Put the reflux flow rate controller in AUTO and

give it a setpoint (SP) of 80 of the total reflux case as a starting point7

Make any operational changes needed to achieve desired operating conditions

Start withdrawing distillate product to maintain a level of 25-75 in the reflux drum Put the distillate flow rate (F003) in AUTO and adjust its setpoint (SP)

unless other instructions specifically call for MANual control

Start withdrawing bottoms product to maintain a constant level of 60 to 80 in the reboiler Put the bottoms flow rate (F004) in AUTO turn on the bottoms

pump and adjust its setpoint (SP) unless other instructions specifically call

for MANual control


Collecting and SavingDisposing of Liquid Samples Sampling needs differ depending on experimental program requirements The TDU is equipped with the following sample points distillatereflux bottoms feed and individual trays DistillateReflux A small sample valve is located just below the total condenser A sample taken via this valve is representative of the current composition of the overhead product There is a small amount of stagnant holdup in the line and valve that must be discarded to get a fresh representative sample Bottoms A small sample valve is located at the bottom right of the reboiler A sample taken via this valve is representative of the current composition of the reboiler contents and hence bottoms product There is a small amount of stagnant holdup in the line and valve that must be discarded to get a fresh representative sample Feed In total reflux mode the only feed used by the column is that which has been

7 This is only a suggested value consistent with previous studies Obviously this rate would be lower than its total reflux counterpart inasmuch as distillate withdrawal will be part of any finite reflux program



charged to the reboiler prior to operations Thus a representative sample of feed for total reflux operations would be taken from the reboiler bottoms sampling valve prior to start of operations In finite reflux mode the feed source to the column is the feed tank in the rear of the unit A small pipette inserted into the lift-top opening of this vessel can be used to retrieve a sample of this material If for some reason this material is not also representative of the contents of the reboiler then reconciling column performance may be problematic Individual Trays Measurement of individual tray performance requires knowledge of tray composition Each TDU sieve tray is equipped with a septum port for retrieving a representative sample of liquid from that tray The use of a curved-needle sampling syringe is essential to collect such a sample The curved needle permits locating the point of the syringe needle at the desired liquid location on the tray while not distorting the septum port

Caution Sampling syringe needle is very sharp Handle with care

SavingDisposing of Liquid Samples

Return all unneeded samples to the feed tank at the end of the day and replace the empty sample vials caps and septa in the tray in the TDU-labeled lab drawer If there are any samples that must be saved for GC analysis at a later time cover the cap of these bottles with Parafilmreg place them in a beaker in the laboratory refrigerator Make sure the beaker is labeled with your name(s) and the chemical nature of the samples

Column Flooding In the course of all runs monitor column loading by careful observation of the trays If a tray fills completely with froth the column may become flooded If this occurs during finite reflux operations the flow of bottoms product would decrease sharply probably to zero or the reboiler level may show a strong steady drop To correct this condition try dumping the tower by reducing reboiler heat input In an experimental program that explores column flooding reaching such conditions can be an explicitly desired part of unit operations

Feed Composition Traditionally TDU feed consists nominally of methanol (~50 wt) isopropanol (~30 wt) and water (~ 20 wt) However particular experimental objectives may call



for different compositions Rely on the Laboratory Coordinator Mr Bob Perkins to prepare monitor and adjust if necessary the feed composition ndash unless otherwise dictated by the experimental program objectives The Lab Coordinator also ordinarily transfers feed from the feed tank into the reboiler in preparation for operations Inasmuch as column performance is highly dependent on feed composition assuming nominal compositional values is likely inappropriate Ternary vapor-liquid equilibrium data for this system has been included as an attachment to this Operating Manual

7 Shutdown Procedure When operations are complete complete the following steps to shutdown TDU safety 1 Turn off all three heaters the bottoms pump and the feed pump 2 Put all controllers except the reflux flow rate in MAN and set their outputs to 0

3 Put the reflux flow rate controller in MAN and set its output (OP) to 20

4 Turn on the reflux pump override and leave the reflux pump on until the reflux drum is empty

5 As soon as the reflux drum is empty take off the reflux pump override turn off the reflux pump put the reflux flow rate controller in MAN and set its output (OP)

to 0

6 Leave the cooling water on until all (six) tray temperatures are below 62 C and then turn it off

7 Close the DeltaV Operate Run program and logoff the workstation from the

Start menu

8 Gas Chromatograph Operation

An Agilent 7890 gas chromatograph (GC) is used to separate and quantify the components in the liquid samples produced by TDU Each component will be recorded as a separate peak in the integrating and recording ChemStation software The elution order is air (eliminate and renormalize if small rerun if not) water methanol isopropanol (not all peaks may register on every analysis)

The following procedure should be used to analyze samples

If you will not be using the GC for an hour or two but will return during lab to make runs place the GC in STANDBYM mode this will save carrier gas You can return it to STARTM when you are ready

At the end of the day place the GC in overnight mode by loading the COOLM method in much the same manner as the STARTM or STANDBYM methods were loaded If the ChemStation presents a menu inquiring whether you want to save changes to the STARTM method say No Do NOT power down the GC and do NOT shut off the helium cylinder

When you are finished all work on the CHE-7890a-02 virtual desktop click the Start icon and then select the Log off option This will log you out of this virtual desktop

If yoursquod like your instructor will demonstrate how to operate the GC It should be in the STANDBYM (or COOLM) method when you arrive If not ask the UO Lab Coordinator or one of your instructors for help

Return all unneeded samples to one of the gallon bottles on the unit at the end of the day and replace the empty sample vials caps and septa in the tray in the TDU-labeled lab drawer If there are any samples that must be saved for GC analysis at a later time cover the cap of these bottles with Parafilmreg place them in a beaker in the laboratory refrigerator Make sure the beaker is labeled with your name(s) and the chemical nature of the samples

9 Additional Operating Data and Considerations

Flow Meter Calibrations8 Current calibrations of all flow meters are as follows (where F = mLmin R = device reading and G = galmin)

Service Instrument Calibration Equation Calibration Range

Reflux Rotameter F = 569R ndash 858 (14 le R le 32) Turbine meter F = 583R ndash 574 (13 le R le 31) Feed Rotameter F = 605R ndash 110 (11 le R le 30) Orifice meter F = 373R + 180 (10 le R le 40) Distillate Rotameter F = 1085R ndash 022 (12 le R le 71) Orifice meter F = 1719R ndash 525 (4 le R le 42) Bottoms Orifice meter F = 1765R + 474 (20 le R le 60) Condenser water Rotameter G = 1189R Full range

[The feed distillate and bottoms meters were calibrated using water at 20C The reflux

8 Inasmuch as instrument calibrations especially electronic instruments can change with time it is wise practice to take backup manual readings from the rotameters (where available) to cover those situations where the electronic counterpart is more suspect



meters were calibrated using water at 17C The condenser cooling water rotameter was

calibrated using water at supply temperature (~90F) and reading the bottom edge of float wide-spot Use relevant meter theory to determine actual flows Reflux and feed rotameter floats are glass (SG = 253) distillate float is stainless steel (SG = 802)]

Instrumentation Issues Turbine and Orifice Flow Meters The reflux turbine meter sometimes does not provide a proper signal to the DeltaV system This typically occurs at flow rates too low to impart sufficient momentum to the turbine If this occurs rely on the rotameter to measure the flow for that service To minimize the occurrence of this problem briefly open the flow control valve completely while in MANual mode in order to get the turbines spinning then cut back

to the desired flow rate Of course because the distillate and bottoms flow rates vary a lot but are key to good material balances their accurate measurement is important Averaging them over a steady-state time span of interest provides the best data (Note that negative readings on some of the flow meters can have physical meaning)

Level P Meters

The reflux drum P level meter works well The reboiler P sometimes does not This is largely due to liquid loss from the top pressure leg which is supposed to

operate full of liquid When the P reading stops changing but the visual level is

changing this problem is occurring When the P meter works correctly it is possible to control the reboiler level directly by closing the cascade from the Bottoms Level Controller to the Bottoms Flow Rate Controller9 Use a level setpoint

consistent with the marks When the reboiler level P meter doesnrsquot work switch the Bottoms Flow Rate Controller to AUTO and adjust its setpoint to keep the reboiler

level approximately constant This should not be hard to accomplish because the bottoms flow rate controller responds rapidly

1 Background Continuous distillation or more precisely continuous fractional distillation is one of the most important unit operations Billions of dollars are invested in equipment to perform this process Distillation equipment typically accounts for some 80 of the capital investment in an oil refinery The Tray Distillation Unit (TDU) is a small pilot unit designed to demonstrate the process of fractionation

2 Description of Facilities The TDU apparatus is a modified version of the Model 9079 Scott Tray Distillation Unit consisting primarily of a small distillation column with six (6) sieve trays an electrically heated reboiler and a total condenser TDU is instrumented sufficiently to demonstrate continuous fractional distillation in the partial separation of methanol from a mixture of methanol isopropanol and water Apart from understanding the basic theory behind the unit operation of distillation sufficiently to study it in an experimental setting it will be necessary to familiarize oneself with the TDU system by studying the detailed schematic in Figure 1 and then tracing out the lines identifying the control and shut-off valves pumps and other instruments The Laboratory Instructor can provide a lsquotour of the unitrsquo to facilitate this An electronic power transducer on the electrically fired reboiler immersion heater indicates directly in watts the reboiler heat duty1 Municipal water provides cooling in the total condenser as measured by the rotameter mounted near the right end of the condenser Electrical heaters provide preheat for the feed and reflux streams Any tray can serve as the feed tray through use of quick connections Liquid sample points allow sampling of feed distillate bottoms and individual tray liquids An Emerson DeltaV control system provides measurement and control of temperature level flow rate and reboiler power Rotameters provide backup measurement capability for distillate reflux and feed flow rates A dedicated Hewlett-Packard gas chromatograph allows offline analysis of feed tray liquid overhead and bottoms product The time required to move from a cold startup to achievement of steady state is typically 90 to 120 minutes From that point moving to a new set of conditions requiring compositional change may take roughly 60 minutes for column compositions to line out to steady-state values2

1 The voltmeter and ammeter mounted near the center of the unit panel display measurements needed to calculate any additional heat supplied by the electrically fired reboiler strip heaters These strip heaters are normally used during heatup of TDU but may not be needed during experimental runs depending on conditions desired Consult with your instructor regarding their use 2 In Fall 2009 just short of 50 lbs of glass marbles were placed in the reboiler vessel substantially reducing its liquid holdup and thus reducing the overall column capacity Reduced capacity has resulted in quicker line out to steady-state conditions and faster column dynamics in general
