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.

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.

How Vane Inlet Devices work? Gas-Liquid Separators

  • Gas Scrubbers, Knockout Drum, Produced Water Separation
Discover how Vane Inlet Devices (VIDs) improve the performance of gas-liquid separators and absorption towers. In this video, we explain the working principle of vane inlet devices and how they combine vapor distribution and liquid separation into a single, efficient system.

Field proven hardware, engineered to last

Spray nozzle distributor with multiple spray nozzles

Spray Nozzle Distributor

  • Tower Internals
Spray Nozzle Distributors use a pressure-fed header and nozzle arrangement to provide controlled liquid coverage across packed beds and process vessels. Nozzle type, spray angle, spacing, and orientation are selected for the required duty, making them particularly suited to irrigation, scrubbing, washing, cooling, and quench applications.

P-PAK random packing element

P-PAK Random Packing

  • Random Packing
P-Pak™ Random Packing is based on the proven Pall Ring design, using punched windows and internal ligaments to increase surface area, improve liquid distribution, and reduce pressure drop. Its robust construction and balanced hydraulic performance make it a versatile solution for a wide range of mass transfer applications.

Fixed valve for distillation tray decks

Fixed Valve Tray Technology

  • Trays
Fixed Valve Trays use permanently formed openings in the tray deck to direct vapour through the flowing liquid, combining effective mass transfer with a simple, robust construction. With no moving valve components, they are particularly suited to high-capacity, fouling, and demanding process services where mechanical reliability is important.
