Batch operations in process

engineering

For the sake o simplicity, manyprocesses in the chemical, pharmaceu-tical or biotech industries can be broken

down into two main areas rom theviewpoint o the sealing technology:

Mixing processes

Agitating, mixing and kneading arebasic unit operations or combining omaterials. The aim is to balance outdierences in concentration and toachieve greater homogeneity.

Applied in sun protection products

at BASF Ludwigshaen.

Mechanical and thermal

separation processes

Centriugation, ltering, drying andevaporating are examples ounit operations or separating

processes. The aim may be to obtain ahigh purity end product or to separateout by-products.


6/24

Mixing processes

Mixing processes are particularly impor-tant in the chemical industry. For a start,intermediate or end products are otenmixtures, dispersions or emulsions, orexample. And, or a chemical reaction,the reactants must be distributed as ho-mogeneously as possible to guaranteean optimum heat and mass transer. Wedistinguish between homogeneous andheterogeneous mixtures. Homogeneousmixtures consist o just one phase, e.g.salt solutions, alloys or air.

Heterogeneous mixtures compriseseveral phases, such as emulsions orsuspensions. As a rule, we use agitatingor liquid phases, kneading or high-viscosity, paste-like media and mixingor solid substances.

Suspendingis the even distribution o solids inliquids. In the starting phase, the solidsat the bottom are whirled up. In the endphase, the solids are evenly distributedin the tank.

Dispersing

Comminuting a substance or breaking agas down and distributing it in a liquid.The aim o dispersing is to increase thesurace area between the disperse pha-

se and the continuous phase in orderto improve the mass transer betweenthem which increases in proportion withthe size o the surace. Dispersing isalso used to stabilise emulsions.

A special technology has beendeveloped or dispersing and micro wetmilling. The application requirementsextend rom low to high viscosity pro-ducts that have to be dispersed down tonanometer range. For these applica-tions, agitated media mills are used to

disperse powdered substances in liquidphases as nely as possible.

This requires particularly robust sealdesigns to guarantee successul operati-on. EagleBurgmann can supply suitableseal systems or all such mixing andagitating applications.

An agitator is generally used or mixingand agitating operations involving mix-tures o substances consisting primarilyo the liquid phase. The requirement ora successul sealing solution is a cleardenition o the operating conditions.

The tasks o the mixing technology canbe described as ollows:

Homogenisation

creates a uniorm phase o several

liquids that are soluble in one anotheror the purposes o balancing outdierences in concentration andtemperature.

Intensication

increases the heat exchange betweenthe liquid phase and the heat transersurace

The separation o mixtures osubstances is one o the most importantunit operation in processes. It normallyrepresents more than hal o theinvestment in a chemical productionplant. The majority o the raw materialsand the products obtained by chemicalreactions are mixtures o substancesthat have to be separated into thedierent components or urtherprocessing or end use. We distinguishbetween mechanical and thermal

separation processes according towhich physical properties are usedor separation. Mechanical separationmethods include e. g. centriugation andltering where dierent densities o thevarious components are used. Thermalseparation methods such as drying andevaporating utilise the dierent boilingpoints or separation.

The ollowing separation processesare o particular importance in sealing

technology.

Centriugation

Separators and decanters separatesolids rom liquids or liquid mixturesand remove the solids at the same time.Centriuges as stand-alone machines orintegrated into complete process linesare used to implement new processtechnologies and make the productionecient and cost-eective. The optionsor using mechanical separation tech-

Mechanical and thermal separation processes

nologies have signicantly increasedover the past ew years. Separators anddecanters are used in the chemical,pharmaceutical and biotech industries,oil and at recovery and starch industryand in industrial biotechnology.

Filtering

Filtering is the mechanical separationo a suspension into the liquid and solidphases using a lter medium. Filtersperorm a large number o solid/liquid

separating applications. For example,modules o dierent designs are used inclosed systems or optimised solutionsthat are matched to the specicapplication.

Drying

By drying, we mean the removal orreduction o the liquid content in asolid by thermal treatment. The liquidis converted into the vapour phase andremoved. Drying involves a very highpower consumption and must be carried

out gently to prevent product deteriora-tion, so it requires particular attention.Thermal drying always stresses thesolid. It is thereore important to ensurethat the process is sae as well asmaintains the product quality.

We distinguish between convection,contact and radiant drying according tothe heat transer method.It is also possible to distinguish by theoperating conditions. For example, with

air drying, the drying is carried out withhot air at atmospheric pressure.For vacuum drying a vacuum is used.This causes the boiling point andthus the drying temperature to dropconsiderably, which makes the processgentler on the product.

Evaporation

Evaporation uses the addition o heat toevaporate and remove the solvent roma solution. This method is used to con-

centrate a solution, or example, to re-cover the pure solvent or to precipitatethe dissolved solid by crystallisation.

Mechanical seals in mixing processes

In closed agitator or vessels, the rota-ting agitator shat must be sealed orom the cover or bottom o the vessel.This type o arrangement is known as atop or bottom entry installation. Thereare also horizontally arranged shatentries and side arrangements that arenot horizontal.

This creates very dierent requirementsor the mechanical seals. To meet usersexpectations o longer service lie or

low investment costs, EagleBurgmannhas developed amilies o seals thatully cover a wide range o applicationsand are based on many years oexperience and development.

These seal designs are standardisedand thus provided the mostcost-eective solution or the required

8

application, but are still extremelyreliable. Engineered solutions are stillneeded or special equipment. The sealdesign depends on the type o installa-tion and the process-specic load. Themechanical, process-specic, physical,chemical and saety requirements mustall be taken into account in the designo the mechanical seal.

Seals may also have additional designeatures depending on the process

requirements. These may include a

Cooling fange

or additional cooling o the seal orprocess temperatures in excess o200 C.

Leakage drain

Leakages o media that could harm theproduct or environment can be drainedo into an external system.

Polymerisation barrier

prevents polymerisation o the productin the dynamic seal area by means o aliquid reservoir on the process side orby fushing.

Resublimation barrier

prevents deposits in the dynamic sealarea released by product resublimationby means o a liquid reservoir on theprocess side or by fushing.

Top entry installation

A top entry installation is generally usedto seal the gas containing headspace.

It should be noted that the dynamicand stationary sealing elements on theproduct side can come into contact withsplasher and oam rom the tank. There

is also a risk o polymerisation in gapsor in the dynamic sealing area.

The maximum speed, temperatureand system pressure to be sealed inthe reactor are important actors thataect the design. The mainly overhungagitator shats are subject to bendingstresses that cause the shat to defectin the seal plane. The mechanicalorces that act on the shat seal andbearing also have to be analysedcareully, as well as unwanted vibrations

caused by internals that aect the fowor special cases, e.g. liquid bearingmissing rom the agi tator.

Shat defections in the seal area o0.1 mm to 0.3 mm are tolerated asstandard, depending on the size o thedrive system and agitator. Up to 2 mmis possible in special cases.

The equipment used in separationprocesses are oten engineered designs,so the seals must be selected anddesigned particularly careully. Top,bottom and side entry installations areall used. The orces acting on the sealduring operation must be considered indetail in advance and must be taken intoaccount in the seal design in order toguarantee an optimum sealing solution.

The emphasis in the seal design is

placed on both the relatively highthermal loads (can be in excess o300 C) and the product deposits inthe area o the dynamic and stationary

sealing elements on the product side.They must not prevent the seal rommoving as required. Process-optimisedseal design with rotating seals on theproduct side (MR series) have provedparticularly successully.

High temperatures can lead toconsiderable thermal expansionbetween the dryer drum and drive shat.There can also be excessive relativemovement, depending on whether the

seal is installed on the drive side orthe non-drive side. These movementsmust be absorbed with metal bellows orspecial defector systems. Such metal

bellows are designed or a specic typeo dryer and the additional orces aretaken into account.

(pressure nutsche lter)

Nutsche lters are used or thediscontinuous ltration o suspensionswith a relatively high solids content.They consist o a fat, cylindricalcontainer with a horizontal lter surace.The modern types are equipped withagitators, which are generally height-

adjustable. The ltration process isoperated under overpressure or under

vacuum. The operating cycle or such anutsche consists o the ollowing steps:

n Filling the nutsche and ltration; theagitator distributes the suspensionuniormly over the lter surace.

n Washing the lter caken Removal o the lter cake, e.g. by

the agitator or by tilting the entirecontainer

Filter dryer (nutsche dryer)

The lter dryer is a variant o thenutsche lter that brings together theltration and the cake drying, generallyunder vacuum, in a single apparatuswith no product transer. The agitator,tank walls and sometimes the tank basecan be heated or drying. Filter dryersare used to process sensitive materialsby gentle drying conditions to a lowresidual humidity.

Conical dryerThis type o dryer is used primarily orbulk goods that must not stick or caketoo much during drying. The materialis circulated gently by a mixing screwwhich rotates both about its own axisand along the tank wall. The conicaldryer can be operated under vacuum orunder overpressure. Heat is supplied viathe wall heater and additionally via theheated screw. There are variants withtop drive or bottom drive design which

has signicant eects on the operatio-nal saety and the ability to empty theapparatus. One particular challenge orthe sealing technology in bottom entryinstallation the sealing o two coaxialagitators moving at dierent speeds.

Double cone dryer

(rotary dryer)

In a double cone dryer, the vessel isset in a tumbling motion by rotation.Thereby the product in the dryer ismixed and comes into contact withthe heated wall. This ensures a good

thermal transer. Usually the doublecone dryer is operated under a vacuumand is suitable or drying ree fowingmedia. The internal space generally hasno internals, so the apparatus is easy toempty and clean. Choppers are some-times used to break up the product. In

apparatuses can oten be opened at theend since the shat is only mounted atone end. Large paddle-dryers can reachup to 20 m3, in which case the shatwill be mounted at both ends.

Depending on the type o equipment inwhich they are used, and on the medium,mode o operation and environmentalprotection requirements, etc, agitatorseals may need additional design eaturesto ensure ecient operation.

As the requirements on mechanical sealincrease, their design, mode o operati-

on and ultimately their supply systemsare changing. The ollowing pages showthe most commonly used and provensupply systems used in state o the artsealing technology or agitator seals.

Barrier or quench systems

or liquid-lubricated single and

multiple mechanical seals

Mechanical seals can only be guaran-teed to work eciently i the space

between the product and atmosphereside o the mechanical seal is com-pletely lled with clean medium. Theliquid reservoir may be un-pressurisedor pressurised.

Quench system

Quench is the term commonly used insealing technology or an arrangementthat applies an un-pressurised externalmedium (liquid) to a mechanical sealssliding aces. The quench perorms atleast one o the ollowing tasks:

n Absorption or removal o leakage bythe quench medium

n Monitoring o the mechanical seals

leakage rate by periodic measure-ment o the level o the quenchmedium in the circulation vessel orthermosiphon vessel

n Preventing o the contact betweenleakage and atmosphere or mediawhich react undesirably with oxygen

n Protection against dry runningn Coolingn Lubrication

Supply systems

Supply systems or liquid-lubricatedmechanical seals can essentially bedivided into two types:

Open circuit: Buer fuid system

A circuit which provides both circulationand pressurisation via a supply system(e.g. EagleBurgmann SPA). The barriermedium is depressurised ater it hascirculated and is collected in an un-pressurised tank.

EagleBurgmann supply systems

Closed circuit: Thermosiphon system /pressure booster or cooling circuit withrell unit

Here, all the components are under thesame pressure. They are pressurised viaan external pressure source or nitrogen(TS system) via a rell system (SPN) orby the process pressure (DRU system).

Beore double seals start-up it is vital,to ensure a sucient rate o circulation

o the barrier liquid. The barrier liquidpressure should be 10 % or at least1.5...2 bar above the maximum pressureto be sealed. To ensure that the slidingaces are lubricated well, the outlettemperature o the barrier medium mustbe regulated via the fow rate so that theboiling point o the barrier medium in thesealing gap is not exceeded at atmosphe-ric pressure. The maximum acceptableinlet/outlet temperature dierential is 15K. The barrier liquid outlet is situated atthe highest point o the seal chamber or

automatic venting o any vapour.

The basic operating conditions denethe ollowing unctions o the supplysystem:

n Build-up pressure in the barrierinterspace

n Compensation o leakagen Circulation o the barrier mediumn Cooling o the barrier mediumn Cooling o the seal

n Lubricating o the sliding aces

Glass-lined agitated tank or producing

various intermediate products. Sealed with

AGS, supplied with nitrogen via GSS4016(background) and SP25 pressure booster

pump (oreground).

Thermosiphon systems

The EagleBurgmann TS system TS 1016or TS 2000 is used to supply barrierfuid to double and tandem seal arran-gement or a wide range o applications.TS vessels are equipped as standardwith all the necessary connections andbrackets. Additional components (e.g.circulating and rell pumps, measuring

equipment, level switches and valvegroups) may be installed as required.The vessel is used or storage, pressuremaintenance and cooling o the quenchor barrier liquid in the sealing circuit.

Design, construction and productionaccording to the EU Pressure EquipmentDirective 97/23/EC. All pressure-loadedwelds are butt-welded or counterbutt-welded by MIG and TIG process.Sockets with recessed gasket (nocontamination o the circuit by threadsealant). Cooling water connections at
