Video

Structured Packing Explainer Video

  • Vacuum Distillation Unit (VDU)
In this video, we explain how structured packing works, how liquid and vapor flow through the packing layers, and why it is widely used in chemical, petrochemical, oil & gas, and environmental processing industries. Learn about its key advantages, including high capacity, excellent separation performance, and energy-efficient operation.

Tray fouling in Sour Water Strippers and Distillation Towers

  • Crude Distillation Unit (CDU), Distillation Column, Solvent Recovery Column, Sour Water Stripper, TEG Contactor (Glycol Dehydration), Vacuum Distillation Unit (VDU)
This animation shows how tray fouling develops, how deposits build up, and how severe fouling can lead to reduced separation efficiency, increased pressure drop, capacity loss, and operational problems.

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.

Field proven hardware, engineered to last

NEW.Gas Injection Support Plate Copy

Catalyst Support Grid

  • Reactor Internals
Catalyst Support Grids provide the structural foundation beneath catalyst and adsorbent beds, carrying the weight of the catalyst and support media while maintaining a high open area for process flow. Grid and beam arrangements are designed to provide the required mechanical strength without unnecessarily restricting gas or liquid passage through the vessel.

R-PAK random packing ring

R-PAK Random Packing

  • Random Packing
R-Pak™ Random Packing is based on the classic Raschig Ring design, offering a simple, robust solution for mass transfer applications. Its durable cylindrical geometry makes it well suited to corrosive, high-temperature, and fouling services where reliability and proven performance are key.

C-PAK random packing ring

C-PAK Random Packing

  • Random Packing
C-Pak™ Random Packing utilises a Cascade Mini Ring-style geometry with a compact 1:3 aspect ratio to maximise surface utilisation and improve vapour flow. The result is higher hydraulic capacity, lower pressure drop, and efficient mass transfer in distillation, absorption, and stripping applications.
