How Chimney Collector Trays Work Absorbers, Distillation, Scrubbers

  • Gas Scrubbers, Knockout Drum, Produced Water Separation
Discover how a Chimney Collector Tray works inside an Absorber Tower and why it plays a critical role in efficient gas-liquid separation. In this video, we explain the design, function, and operating principle of a chimney tray, including how it collects liquid, allows vapor to pass through the chimneys, and ensures proper liquid redistribution to the sections below.

Bubblecap Cartridge Trays

Cartridge Trays

  • Tower Internals, Trays
Cartridge Trays are modular, pre-assembled tray systems designed to simplify installation and replacement inside process columns. Their compact construction reduces internal assembly work and makes them particularly useful for restricted-access vessels, small-diameter columns, and retrofit projects where minimising shutdown time is important.

Cyclone Box Assy

Gasumax Cyclones

  • Mist Elimination
GasuMax™ Cyclones use centrifugal force to separate entrained liquid droplets from gas and vapour streams. Designed for high gas velocities and heavy liquid loading, they provide reliable mist elimination with no moving parts, making them ideal for gas-liquid separators, scrubbers, and process vessels.
