Mesh Pad D-Mister Mist Eliminator Explainer Video

  • Gas Scrubbers, Knockout Drum, Produced Water Separation
Discover how a D-Mister pad (mist eliminator) plays a critical role in an absorber tower by removing entrained liquid droplets from the vapor stream. In this animation, we explain the complete separation process—from droplet capture and coalescence to gravity drainage—showing how the D-Mister pad ensures clean vapor exits the tower.

Sour Water Stripper Explainer Video

  • Sour Water Stripper
In this animation, we take a closer look inside a Sour Water Stripper (SWS) and explain how it removes contaminants such as hydrogen sulfide (H₂S) and ammonia (NH₃) from refinery sour water.

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.

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.

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.

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.
