Procedure 5-11 Design of Demisters

Demister pads or mist eliminators are important inter-nals in process vessels Anytime there is a continuous twophase flow vapor and liquid there is the possibility forliquid entrainment If it is desirable to separate the liquidand vapor or prevent liquid carryover in the vapor streamthe velocity must be kept sufficiently low to allow the liquiddroplets to fall out of the vapor stream Demister pads areeffective entrainment separators which allow operation atvapor velocities that would otherwise be excessive

ldquoVapor disengagementrdquo can be accomplished withouta demister but the vessel must be made much larger toaccomplish the same degree of separation This is knownas gravity separation

Demister pads are used in a wide variety of processvessels Good performance can be achieved at velocitiesof 30 to 110 of optimum

Demister pads can be used in vertical or horizontalvessels The mesh pad orientation can be either vertical orhorizontal in a vertical or horizontal vessel

A wire mesh demister consists of a knitted wire matmounted on a light weight support grid The mesh is madeby weaving small diameter metal wire into a mesh Padsmay be made out of metal or plastics Metal type includecarbon steel stainless steel monel and others Plasticmaterials include PTFE HDPE and PP

Pressure drop is usually extremely low in the range of1 inch of water column maximum The pressure drop isnormally so low that it is ignored in design

Vapor disengagement is dependent on the velocity ofthe stream The most common equation for determining theallowable vapor velocity for two phase flows is as follows

Va frac14 K frac12ethrL rVTHORN=rV1=2

Where

Va frac14 Allowable vapor velocity FtSecK frac14 Constant or coefficientrL frac14 Density of liquid PCFrV frac14 Density of vapor PCF

Notes

1 The mesh pad shall be in one piece or sectional asrequired for insertion through the vessel manwayEach pad section shall be removable through thevessel manhole

2 Layers shall not be more than 6 inches thick3 Where more than one layer is required all joints

shall be staggered

4 One piece circular pads may be spiral in form5 Each section of mesh shall include a grid on one or

both sides The grid wire andor fastening deviceshall be the same material as the mesh pad Top andbottom grids shall be constructed of frac14 inch diam-eter rods welded to ⅛ inch by 1 inch bars Themaximum gap between mesh pad and grids shall befrac12 inch for diameters less than 84 inches and 1 inchfor larger diameters

6 Estimate grid weights as 3 PSF7 Tie down wires shall be 1=16 inch diameter wire thru

frac14 inch diameter holes on 4 inch centers Tie wiresshould not be pushed through the pad as this couldcause leak paths

8 Pressure drop across mist eliminator shall beassumed as 02 PSI for support design

9 Unless otherwise specified support rings shall be2 inches wide for pads 84 inches in diameter andless and 3 inches wide for larger diameters

10 The mist eliminator shall be a tight fit against theshell or enclosure as well as between sections Meshpads shall be⅜ inches oversize all around for a forcefit against the enclosure No gaps are allowed

11 Vessel fabricator shall provide the mesh and gridsas well as any stiffeners required

12 The Mist eliminator shall be specified as either topor bottom removable

13 ldquoKrdquo is a constant or coefficient that is a functionof the efficiency of the separation K-values rangefrom 04 to 43 but are generally in the 15 to 35range The K-value is affected by pressure type ofpad size of wire type of vessel and disengagingheight For pressure applications the K-valueshould be decreased by 01 for every 100 PSI ofpressure after 100 PSI

14 Wire diameter for the mesh pad itself vary from0003 to 0016 inches

15 The free volume of demisters range from 92 to994

16 The density of the pads ranges from 3 to 33 PCF17 The NSA (nominal surface area) is the surface area

to volume ratio Ft2 Ft3 and is an important indi-cator of performance Ratios range from 50 to 600

18 To obtain higher separation efficiencies the wirediameter is decreased and the density and thicknessare increased

19 Typical width of sections for multi-section pads is12 inches (300 mm) but may vary by manufacturer

Procedure 5-12 Design of Baffles [10]

Baffles are frequently used in pressure vessels eithervertical or horizontal to divide the interior volume intodifferent compartments These compartments may beused to segregate liquids or provide overflow weirs forthe separation of liquids Baffles may be stiffened orunstiffened When welded across the entire cross sectionof the vessel they must be checked that they are notunduly restricting the diametral expansion of the vesselIf the unrestrained radial expansion of the vessel exceedsthat of the baffle by more than 1=16 in (⅛ in on thediameter) then a ldquoflexiblerdquo type of connection betweenthe vessel shell and the baffle should be utilized Variousflexible attachment designs are shown within theprocedure

Baffles should always be designed in the corrodedcondition It is typical for welded baffles to be designedwith a full corrosion allowance on both sides If the baffleis bolted in then one-half the full corrosion allowancemay be applied to each side the logic being that a boltedbaffle is removable and therefore replaceable

The majority of baffles are flat and as a result are veryinefficient from a strength standpoint Deflection is thegoverning case for flat plates loaded on one side Thepreference is to have unstiffened baffles and they shouldalways be the first choice This will be acceptable forsmall baffles However for larger baffles as the bafflethickness becomes excessive stiffeners offer a moreeconomical design Therefore stiffeners are frequentlyused to stiffen the baffle to prevent the thickness of thebaffle from becoming excessive The number size andspacing of stiffeners are dependent on the baffle thicknessselected There is a continual trade-off between bafflethickness and stiffener parameters

The design of a baffle with stiffeners is an iterativeprocess The procedure for the design of the stiffeners isfirst to divide the baffle into ldquopanelrdquo sections that are rigidenough to withstand the pressure applied on one sideEach individual panel is checked as a flat plate of thedimensions of the panel The stiffeners are assumed to bestrong enough to provide the necessary edge support forthe panel

The stiffeners themselves are designed next A sectionof the baffle is assumed as acting with the stiffener and ascontributing to the overall stiffness This combinedsection is known as the composite stiffener Thecomposite section is checked for stress and deflectionBoth vertical and horizontal stiffeners can be added asrequired

If required an alternate design is assumed based ona thicker or thinner baffle and checked until a satisfactorydesign is found There is no ldquorightrdquo answer however itshould be noted that the thinner the baffle the greater thenumber of stiffeners The lightest overall weight isprobably the ldquobestrdquo design but may not be the leastexpensive due to the welding costs in attaching thestiffeners

One alternative to a flat baffle with stiffeners is to go toa curved baffle A curved baffle works best as a verticalbaffle in a vertical vessel The curved baffle takes pressurefrom either side wall If the pressure is on the concave sidethe baffle is in tension If the pressure is on the convexside the baffle is in compression

There are various tables given in this procedure for flatplate coefficients Flat plate coefficients are utilized todetermine the baffle thickness or a panel thickness Eachtable is specific for a given condition and loading

Limit deflection to the smaller of tb2 or b360 Ifdeflection is excessive then

a Increase the baffle thicknessb Add stiffenersc Go to curved baffle design

If stiffeners are added the first step is to find themaximum ldquoardquo and ldquobrdquo dimensions that will meet theallowable deflection for a given panel size This willestablish the stiffener spacing for both horizontal andvertical stiffeners The ultimate design is a balancebetween baffle thickness stiffener spacing and stiffenersize

Stiffener Design

Divide baffle into panels to limit deflection to the lesserof tb2 or b360 Deflection is calculated based on theappropriate Cases 1 through 3

bull Check baffle for panel size a0 b0bull Check stiffener for length a or b

Recommendations for attaching stiffeners

Benefits Provides added stiffness and no corrosiontrap
