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.

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.

Field proven hardware, engineered to last

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.

Sieve Trays

  • Trays
Sieve Trays use a pattern of fixed perforations to disperse vapour through the liquid flowing across the tray, creating effective vapour-liquid contact for mass transfer. With no moving parts, their simple and robust construction makes them an economical choice for distillation, absorption, and stripping duties with relatively stable operating loads.

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.
