TheEvenflowHEInletdevicereceivestheincomingprocessstreamdivertingthefluidsthrough thedistributionvanes.Inspreadingthehighmomentumflowoverawiderareafillingthecross sectionalareaofthevessel,significantlyreducesthemomentumofthefluidenteringthe separatorinletzone.TheEvenflowHEinletdevicehastwokeybenefitstoimproveseparation. Firstly, by dissipating the momentum as early as possible in the inlet zone, reduces turbulence in theinletzoneanddownstreaminthevessel.Secondly,creatinganevendistributionoftheinlet stream utilizes the full vessel volume improving residence time. ThedesignoftheEvenflowachievestheseimprovementsintheinletzonewithoutimpactingor breaking up liquid droplets. This reduces the presence of small entrained oil droplets carried over to downstream demisting device and reduces gas entrainment in the liquid phase. TheEvenflowHEinletdevicehasbeendevelopedandrefinedextensivelythroughthecombined findingsofCFDsimulationandsuccessfulcasestudiesandhasbeenappliedtoawiderangeof applicationsforhorizontalandverticalseparators.Replacinganexistinginletdevicewithan EvenflowHEcanenabletheexistingprocessvesseltoeffectivelyhandlethehigherinlet momentums andchanged production profile ensuring economical process performance for future flow rates. Key benefits: Robust technology applied over decadesProven performance optimized by CFD Robust design with mechanical strength verified by FEA Resistant to fouling and blocking Effectively dissipates inlet momentum Maximizes gravity separation Evenly distributes fluid flow to utilize full vessel volume.

No. :P14-04027-PDC Revision : 2 Page 5 of 17 3.2Mesh Pad Demister The mesh pad demister is a well-established design for dealing with liquid droplets entrained in the gasphase.Thistypeofdemisterischaracterizedbyaverylowpressuredropandhighcontact area for fine liquid droplets. A lattice is woven from fine wire creating a mesh and supported within anopenframeformechanicalstrength.Themeshprovidesahighnetfreeareawithahigh surface area for contact with fine liquid droplets. As the droplets make contact with the mesh, they coalesce and grow in size. As the droplets coalesce and grow, a critical mass is reached when they fall under gravity from the bottom of the mesh. The mesh can be mounted horizontally or vertically in two or three phase separators. In Summary, Mesh Pad demisters are: Resistant to erosion and degradation Highly efficient, with a wide turn down and operating range Robust technology applied over decadesProven performance optimized by CFD Robust design with mechanical strength verified by FEA Low cost and weight FMC Project No.:P14-04027 FMC Doc. No. :P14-04027-PDC Revision : 2 Page 6 of 17 3.3Distribution Baffles Perforated baffles are positioned in horizontal separators to achieve a number of process benefits:The effects of high inlet momentum of incoming fluids are contained within the inlet zone Distribute pressure drop across the vessel diameter creating plug flow Resulting pressure drop promotes gas break out earlier in the separation zone.Reduces impact of fluid volume surges from fluctuating process conditions.Createscalmseparationconditionstomaximizethevolumeinthedownstreamquiescent zone.Reduce gas layer velocities, allowing for drop out of liquid droplets. In floating applications, correct placement of baffles provides effective sloshing mitigation The inlet momentum of multiphase fluid entering a separator vessel must be effectively contained withintheinletzonewhileminimizingturbulenceandshearing.Mostofthemomentumwillbe dispersed by the inlet device ensuring gooddistribution of fluid flow across the inlet zone. When fluctuating flow is experienced, changing velocities, phase ratios and slugging has the potential to agitatetheinletzone.Bafflespositioneddownstreamoftheinletdeviceservetocontainsurges within the separator inlet zone. Perforated baffles are designed with an open area between 20-40% creating the desired level of pressuredrop.Bycreatingthepressuredropacrossthewidthofthevesselprovidestwodirect benefits to separation efficiency:1.Ensuringplugflow.Usingthefullwidthofthevesselpreventsjettingorshortcutting downstream towards the outlet nozzles 2.Gas phase hold up.
