How Distillation Floating-Valve Trays Work

  • Gas Scrubbers, Knockout Drum
Distillation valve trays use movable valves that open with rising vapor, allowing it to bubble through liquid and create efficient mixing for mass transfer. Their self-adjusting design maintains stable performance by adapting to changing vapor flow conditions.

Case Study

Glycol Still Internals Replacement – Britannia North Sea

  • Glycol Still Column
After almost three decades of service, the Glycol Still at the Britannia North Sea facility was scheduled for replacement. Rosenberg verified the process design and supplied a complete new internals package, including P-Pak™ random packing and RoseFlow™ internals, engineered for reliable long-term offshore service.

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.

Field proven hardware, engineered to last

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.

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.

D-Mister knitted mesh mist eliminator pad

D-Mister Mist Eliminator

  • Mist Elimination
D-Mister™ Mesh Mist Eliminators use knitted wire mesh to capture, coalesce, and drain entrained liquid droplets from gas streams. Their high void fraction provides excellent separation efficiency with low pressure drop, making them ideal for process vessels, scrubbers, separators, and distillation columns.
