Gas-Liquid Separator Internals for Dirty Service: Mesh vs. Vane

[KernOily]

Hi guys. Any of you have experience with separator internals for dirty gas service? Have run mesh-type and they keep plugging up with iron sulfide and other detritus that comes in with/plates out from the gas. Looking to see if anybody knows if a vane-type mist eliminator would also suffer from plugging.

Separator inlet stream is outlet stream from a cooler/condenser (fin-fan), 34% vapor mass fraction, 2.5 MMscfd, 65% CO2/35% C1/water-saturated, 150° F, 0.3 psig, 7500 ppm H2S.

Thanks guys!! Pete

Low turndown for vanes. Perhaps worth investigating corrosion-resistant wiremesh. There should solutions be out there.

Though these are better for fouling service applications from a plugging risk perspctive, the tradeoff is poorer liquid separation eff with either single or double pocket vane type demisters.

Thanks for the replies guys. Much appreciated. This gives me some direction. Thank you! Pete
