RASCHIG JAEGER COLUMN INTERNALS

FEATURESThe performance of packed columns that use modernhigh efficiency packings is closely related to theperformance of the other internals such as liquiddistributors and collectors. Packed towers work as aunit so careful selection and design of the properinternals is crucial.

Raschig-Jaeger offers a complete line of towerinternals to be used with random or structuredpackings. These internals are specifically designedand selected to maximize the performance of thepackings and can be used effectively in many differentcombinations. Jaeger internals are available in metal,plastic, ceramic or fiberglass for applications incorrosive, hot, and/or pressurized chemical systemsas well as for hydrocarbon applications and ambientair-water systems

Contents of a Packed ColumnThe contents of a packed tower will vary based onapplication and performance requirements. Thecolumn at the right illustrates the various componentsthat might be used in typical installations. Generally,the column will contain a gas inlet, a packing supportplate, random or structured packing, a bed limiter, aliquid distributor, vapor outlet, and perhaps a misteliminator. Most column internals are custom designedfor the intended application and therefore vary indescription and performance. Many process columnsutilize multiple liquid feed inlets and draw traysrequiring careful and detailed design.

ORIFICE PAN LIQUID DISTRIBUTORSDR-2Orifice pan liquid distributors, type DR-2 by Raschig-Jaeger aremanufactured in various sizes and designs . Typically all sizes haveround or rectangular chimneys. The distributor floor of both the pan andplate distributors consists of liquid discharge holes on a square ortriangular pitch and circular chimney risers for the gas flow. For smallcolumn diameters where pan type distributors are utilized, gas can passthrough the annular space between the outer perimeter of the pan andinner wall of the column. The annular space is formed by elevating thepan above the support ring with support feet or lugs evenly distributedaround the perimeter of the pan. DR-2 distributors can also act as bedlimiters by locating anti-migration bars/rods on the bottom end ofchimney risers that form open areas. These devices can sometimes beused as redistributors with the addition of Hoods over the vapor risers.Orifice pan liquid distributors can be made in plastics, metals orceramics.

WEIR-RISER PAN LIQUID DISTRIBUTORSDR-3This type of liquid distributor/redistributor is used when great variationsof liquid flow need to be handled. They are suited for diameters up to48". The DR-3 Pan distributor consists of notched or V-Weir shaped gasrisers such that the vapor-liquid traffic share the same flow area. Thevapor or gas velocity through the risers typically limits the maximum flowrate for this style of distributor. Compared to other distributors, the DR-3provides a low distribution quality. The DR-3 is suitable when the foulingtendency is high. Additionally a wide turn-down range is possible due tothe weirs which allow greater flow rates as liquid head increases.

Like the DR-2 gas can pass through the annular space between theouter perimeter of the pan and inner wall of the column. The annularspace is formed by elevating the pan above the support ring with supportfeet or lugs evenly distributed around the perimeter of the pan.

LATERAL PIPE DISTRIBUTORS WITH PRESSURIZED FLOWDP-1The DP-1 model distributor is a pipe-ladder type which can be designedfor a wide variety of applications. It is a pressure driven distributor wherethe liquid is delivered through metering orifices in the branch pipes.Typical pressure drop is 1 – 5 psi (68.95 – 344.7 mbar). DP-1distributors are commonly utilized in scrubber and stripper services withmoderate-to-high liquid rates. The DP-1 is not recommended for lowliquid rates or fouling systems or ones with suspended solids due to thepotential for plugging of the metering orifices. Conditions which favor theuse of a DP-1 include high vapor velocities and limited space availability.DP-1 distributors can be made in a variety of plastics and alloys.



ORIFICE PLATE DISTRIBUTORS/REDISTRIBUTORS

RP-2Orifice plate liquid redistributors, type RP-2, are manufactured in varioussizes and designs. Typically all sizes have round or rectangularchimneys with a flat floor sealed to the vessel support ring. The liquidredistributor type RP-2 typically consists of a flat or an integral truss traydeck with liquid discharge holes on a square or triangular pitch, andrectangular chimneys for the gas flow at column diameters > 1200 mm.The chimneys are covered with hoods. For large diameter columns,liquid is evenly distributed to the orifice deck by using one or more mainParting Boxes which are usually fed by a feed pipe pre-distributionsystem. Liquid is fed to the parting boxes from the feed pipe dischargeoutlets. To dampen the impulse of liquid entering the liquid distributorand ensure uniform distribution, a Parting Box is fitted with a perforatedsplash guide calming device filled with Raschig Super-Rings. Superrings are held in place with an expanded metal screen cover plate.Alternatively if column space is limiting, the parting box forms a centralchannel in which the height is the same as the troughs. Troughs areusually bolted on the parting box central channel and gasketed to ensuretight liquid seal.

To accommodate an operating range greater than 1:2, the RP 2 specialdesign contains liquid discharge tubes that extend from the orifice deck.Each liquid discharge drip tube incorporates lateral holes of appropriatesize to handle the different liquid loads.

The RP2 special design is employed for a high liquid rate service, inwhich there are 2 key design features. First, the parting box describedabove is made taller to accommodate the high liquid flow rate from theexternal feed and liquid falling from a packed bed above. Uniform liquiddistribution is achieved and any flashing resulting from the mix isisolated from the main distributor liquid pool. Second, the distributor isdesigned with tall vapor chimneys to maximize liquid volume holdup andresidence time. High residence time allows better liquid-vaporseparation in the liquid pool and reduces the impact of such on themetering orifices on the drip tubes.

The liquid redistributor type RP 2 is similar to that described aboveexcept that the gas chimney risers are covered with hoods to prevent theliquid from raining through the distributor.

RP-2 liquid distributors/redistributors are available in plastics, metals orceramics.

TROUGH LIQUID DISTRIBUTORSDT-1DT-1 Trough Distributors are Raschig-Jaeger’s most versatile model.Their applications range from low liquid rate and high purity distillationsystems to high liquid rate and fouling services, depending on specificdesign features. The DT-1 is a narrow trough type distributor with eachtrough consisting of ground holes, or drip tubes or lateral holes on thewalls of each trough. Liquid flow into the troughs occurs with one ormore main Parting Boxes (depending on column size) that are typicallyfed by a feed pipe pre-distribution system. To dampen the impulse ofliquid entering the liquid distributor and ensure uniform distribution, theParting Box is fitted with a perforated splash guide calming device filledwith Raschig Super-Rings. Super rings are held in place with anexpanded metal screen cover plate. Alternatively if column space islimiting, the parting box forms a central channel in which the height is thesame as the troughs. Troughs are usually bolted on the parting boxcentral channel and gasketed to ensure tight liquid seal.

When a large Turndown is required, two or more rows of holes arelocated on each drip tube or both walls of each trough to handle the wideliquid flow rate range. The Turndown specifically is 2:1 for single orificedesign and up to 10:1 for multi-orifice and/or slot, V-notch design.

WEIR-TROUGH LIQUID DISTRIBUTORDT-2The liquid distributor DT 2 is suitable for handling liquids with solidparticles. It consists of troughs with lateral V-shaped notches asdischarge orifices. The lateral notches are covered with L shaped guidechannels to minimize gas interference with the descending liquid and tocommunicate liquid directly on to the packing. The main predistributionbox also consists of larger rectangular slots that are covered with U-shaped guide channels. They communicate liquid to each of thedistribution troughs. To dampen the impulse of liquid entering thepredistribution box, the two discharge openings of the feed pipe areenclosed with impingement plates. These plates effectively reduce thepredistribution box width at the point of liquid entry by attachment to thepredistribution box wall with bolts and spacers.

DT-1 Standard



HIGH QUALITY LIQUID DISTRIBUTORDT-SThe liquid distributor type DT-S is a trough type distributor with eachtrough consisting of liquid discharge drip tubes and/or lateral holes in thewall of each trough. In the drip tubes, lateral holes are positioned a shortdistance above the trough floor, thus allowing for the settling of somesolid particles. The liquid discharge flow drip tubes will each containslots at the top to account for any liquid overflow. Liquid flow from thelateral holes on the trough walls is guided directly on to the packing bymeans of enclosed narrow vertical liquid U-shape guide channels. Thedischarge point of the U-shaped guide channels are typically positionedapprox 0.75 inches (20 mm) above the top of the packing, thusminimizing any potential liquid entrainment at high gas rates. Liquid flowinto the troughs occurs with one or more main Parting Boxes that aretypically fed by a feed pipe pre-distribution system. To dampen theimpulse of liquid entering the liquid distributor and ensure uniformdistribution, the Parting Box is fitted with a perforated splash guidecalming device filled with Raschig Super-Rings. Super-rings are held inplace with an expanded metal screen cover plate. Alternatively if columnspace is limiting, the parting box forms a central channel in which theheight is the same as the troughs. Troughs are usually bolted on theparting box central channel and gasketed to ensure tight liquid seal.

When a large Turndown is required, two or more rows of holes arelocated on both walls of each trough to handle the wide liquid flow raterange. The Turndown specifically is 2:1 for single orifice design and upto 10:1 for multi-orifice and/or lateral holes in the walls of each trough.

HIGH QUALITY MULTI-FLOW LIQUID DISTRIBUTORDT-MFThe high quality liquid distributor DT-MF is a trough type distributor thatis ideal for handling extremely low liquid loads 2.05 gpm/ft2 (< 5m3/m2/h). It consists of narrow distributor troughs fitted with regularlyspaced small side boxes. Each small side box contains the Multi-FlowMF drip pipes. There are lateral holes located on the walls of the DTtroughs that communicate liquid to the side boxes and into the MF dripflow tubes. The lateral holes are positioned a short distance above thetrough floor, thus allowing for the settling of some solid particles. Thecentre DT-MF trough requires the middle row of MF devices to be pre-installed prior to entering the column.

The narrow troughs are fed by a main parting box. It is located above thetroughs and typically fed by a feed pipe pre-distribution system. Todampen the impulse of liquid entering the liquid distributor and ensureuniform distribution, the Parting Box is fitted with a perforated splashguide calming device filled with Raschig Super-Rings. Super-rings areheld in place with an expanded metal screen cover plate. The DT-MFcan be leveled with a set screw leveling device.

DP-S


SPRAY NOZZLE DISTRIBUTORDP-SModel DP-S liquid distributors are similar to the pipe-ladder DP-1design except that the liquid is delivered to the packing throughpressure driven spray nozzles. Typical pressure drop for this design is5 – 20 psi (345 – 1379 mbar) and turndown is typically limited to 2:1.The piping and spray nozzle layout depends upon parameters such astower size, liquid flow rates, fouling potential, and available space. Thepreferred application for the DP-S is direct contact heat transfer;however, they have been successfully employed in many scrubbingand stripping applications as well. They are not recommended for mostdistillation services. DP-S distributors can be made in a variety ofplastics and alloys.

LIQUID COLLECTORCP2The liquid collector CP2 is derived form the liquid-redistributor RP2. Itconsists of integral truss solid decks with round or rectangular gas-chimneys and includes a draw-off sump. The gas-chimneys arecovered by hoods that prevent the liquid from raining through the risers.It serves as a liquid collector / mixing tray in between packed beds anda liquid draw. It contains short downcomer pipe(s) to conduct liquid intothe Parting Box of a CR2 liquid distributor. To prevent liquid leakage,adjacent liquid collector tray decks can be fitted with gasketing or sealwelded.

CHIMNEY COLLECTOR/VAPOUR DISTRIBUTOR TRAYCP2The liquid collector/vapour distributor is similar to that described above.For designs with tall chimney risers, the risers are manufactured inmodules and welded together either in the Raschig-Jaeger Workshopor at site prior to welding on to the distributor/collector deck. It servesas a liquid collector / vapour distributor tray in between packed bedsand a liquid draw. The CP2 consists of downcomer pipe(s) to conductliquid into the Parting Box or Boxes of a trough-type liquid distributor(DT-1, DT-2, DT-S). To prevent liquid leakage, adjacent liquid collectortray decks can be fitted with gasketing or seal welded.

VANE TYPE LIQUID COLLECTORCV 1The vane type liquid collector CV 1 consists of inclined and overlappinglamellas. The channels at the lower end of the lamellas lead thecollected liquid into an annular channel which follows the column wall.The liquid collector CV 1 causes an extremely low pressure drop.

FLTA BAR SUPPORT GRID (STRUCTURED)SP-PSupport Gratings are the simplest and least expensive type ofpacking supports. They also utilize the least vertical space. Theyare made of rectangular flat profiles that are dimensionedaccording to their corresponding mechanical stress. This flat profilesupport plate is typically used with structured packings. Thesupport grids are available in various materials such as plastic,FRP and metals. They can also be used as bed limiters.Sometimes support beams are required for structural reasonsdepending on the material and size of the support grate.

MULTIBEAM SUPPORT PLATESSP-1Gas injection or multibeam support plates, are supplied in varioussizes and designs. They comprise of corrugated sheets perforatedwith slots to separate gas and liquid flow paths maximizing totalthroughput. The uniform pattern of the slots is such that the openarea approaches or exceeds the cross-sectional area of the tower.Normally the slots on the top and sides are allocated for gas flowwhile those on the floor/valleys are designated for liquid flow. Theslots are sized to prevent packing elements falling through them.The angle of corrugation, height and width of each beam varieswith design and material used. The multibeam support plates areavailable in various metals, plastics and ceramics. Sometimes inlarger diameter towers proper gussets inside the beams as well assupport beams (which are usually supplied by the vessel fabricator)are required for greater loads. In plastics, properly encapsulatedFRP or steel rods are sometimes provided to add to the structuralstrength of the beams. Units are normally made either in one pieceor sections depending on ease of installation and manway openingsize.

MULTIBEAM SUPPORT PLATES (Small Columns)SP2The segmented SP 2 support plate is typically used for columndiameters < 4 ft (1200 mm). It is characterized by its sinusoidalperforated corrugation design that ensures a high open area andmechanical stability. The free cross section is above 100%.

GAS DISTRIBUTORS

PIPE AND SHELL GAS DISTRIBUTORGV 1The vapor feed-pipe GV 1 is either perforated or slit on theunderside or executed as an open pipe section. The gas exitsdownwards from the orifices, is deflected and flows into the packedbed.

VANE TYPE GAS DISTRIBUTORGV 2The GV 2 gas/vapor distribution systems with guides vanes(Schoepentoeter style) are complex structures but efficient withlarge column diameters. It encourages the distribution of thegas/vapor phase through increased turbulence and reducedpressure drop, promoting the agglomeration of the drops.

VAPOR DISTRIBUTOR-COLLECTORGV 3The gas distributor type GV 3 is a modified liquid redistributor withrectangular gas-chimneys that prevent the liquid from rainingthrough the distributor. The gas distributor is equipped with adowncomer shaft or with drain pipes.

GAS-LIQUID PHASE SEPARATORS

TWO-PHASE DOUBLE-SHELL FLASHBOXFB 1The Flashing feed device type FB1 is used for two phase-feedstreams and consists of a double-shell inlet pipe. The two phaseflow is led into the central pipe. The gas enters the interstitial spaceof the double-shell pipe through a perforation in the upper sidewhile the liquid flows out downwards through discharge holes. Thegas is diverted downwards in the double-shell pipe and enters thecolumn axially through discharge openings on the outer pipe shell.

TWO-PHASE CENTRIFUGAL FLASHBOXFB-2The Two-Phase Centrifugal FlashBox processes a two-phase feedentering the column and FB-2 tangentially. The centrifugal forceseparates the phases such that vapor ascends to say the nextpacked bed above. The liquid on the other hand descends to aliquid collection/distributor system by means of perforations alongthe floor of the FB-2 box.

TWO-PHASE FLASH GALLERYFB-3The flash-gallery FB 3 is used for the two phase feed separation inlarge columns. It consists of an annular channel that lies on asupport ring and has discharge holes in the channel floor whichusually lead the liquid directly onto the redistributor lying below.The gas can exit the annular channel upward along the entirelength of the annular channel. In most cases the liquid distributorlying below the flash-gallery is the type RP 2 to form the FB 3/RP 2combination.

MESH PAD MIST ELIMINATORS

ME1Raschig-Jaeger offers high efficiency wire mesh mist eliminators. Thesehighly reliable and efficient mist eliminators consist of coils or layers ofknitted wire mesh. They are usually held together by top and bottomsupport grids. The complete unit is secured, either from the top or thebottom, to a support ring welded into the column. The mesh and gridmaterial can be metal or plastic depending on the application. Propersupport beams are sometimes required to provide structural strength.

The mist is carried upward by the gas flow, impinges on the wire meshand separates from the gas flow. At the point of separation, the miststarts to flow downward through the wire mesh and unites to form largedroplets which then fall down into the vessel. The separationperformance is influenced by the wire diameter and specific surface areaof the wire mesh and increases with gas flow velocity. A maximum flowvelocity is not to be exceeded, however, since it would cause the dropsto blow through. Flow velocity, pressure drop and fractional separationefficiency for different droplets' diameters can be calculated inaccordance with the gas and liquid operating conditions and propertiesand the type of mist eliminator selected.

CHEVRON MIST ELIMINATORS

ME2Raschig-Jaeger can supply chevron or plate type mist eliminators. Theyare suitable for high liquid load, dirty services and high capacities. Theycan be applied in horizontal flow or used in vertical up-flow. The chevronunits can also be supplied with proper housings. They can be made insections to be installed through a man-way. Droplet sizes down to 10microns can be removed. Most specs can be met when these arecombined with mesh pad mist eliminators (ME1). The chevron units canbe made in plastics or metals.
