Case Study

MIBK Steam Stripper Process Optimisation

  • MIBK Steam Stripper
Rosenberg conducted a detailed process and hydraulic study of GSK’s MIBK Steam Stripper in Irvine, identifying unstable sieve tray operation as a key cause of recurring fouling and developing process improvements to increase stripping efficiency and operational stability.

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.

Video

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.

Field proven hardware, engineered to last

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.

ROSEPAK-S smooth structured packing element

ROSEPAK-S Smooth Structured Packing

  • Structured Packing
ROSEPAK-S™ Smooth Structured Packing features smooth corrugated sheets that minimise pressure drop, reduce liquid hold-up, and resist fouling by discouraging the build-up of solids and process contaminants. It is ideally suited to vacuum distillation, fouling services, and other demanding mass transfer applications.

DEPSEP-C corrugated plate pack coalescer

DEPSEP-C-Plate Packs (Corrugated)

  • Coalescers
DEPSEP™ Corrugated Plate Packs create multiple inclined flow channels that promote laminar flow and enhance oil-water and liquid-solid separation, making them ideal for CPI separators and produced water treatment systems.
