Liquid Carryover in Separators : Explainer Video

  • Gas Scrubbers, Knockout Drum, Produced Water Separation
Liquid carryover is one of the most common and costly problems in gas separation systems. In this animation, we explain how liquid carryover occurs, why it happens, and the impact it can have on downstream equipment.

MultiMister Technology For Gas Scrubbers

MultiMister Mist Eliminator

  • Mist Elimination
MultiMister™ Technology integrates cyclonic, vane, mesh, and fibre bed mist elimination into a single engineered system. By combining multiple separation stages, it efficiently removes a wide range of liquid droplet sizes while protecting downstream equipment and improving overall process performance.

NEW.Catalyst.Outlet.screen.Gray.1

Catalyst Outlet Collector

  • Reactor Internals
Catalyst Outlet Collectors gather gas or liquid leaving a catalyst or adsorbent bed and direct it towards the vessel outlet while retaining the bed media. High open-area screening provides an efficient collection path with minimal flow restriction, helping prevent catalyst carryover and protect downstream equipment.

DEPSEP-C corrugated plate pack coalescer

DEPSEP-F-Plate Packs

  • Coalescers
DEPSEP™ Flat Plate Packs increase the effective settling area within gravity separators, allowing oil droplets and suspended solids to separate more efficiently while reducing equipment footprint and improving throughput.
