Case Study

UZ750 Produced Water Separator Expansion

  • Produced Water Separation
ADNOC required a 50% capacity increase for produced water separation at Upper Zakum 750, from 100 KBPD to 150 KBPD. Rather than requiring a new, larger separator vessel, we engineered an extension to our existing plate pack technology, enabling the increased throughput while retaining the existing equipment.

Case Study

Fractionator Tower Valve Tray Replacement

  • Crude Distillation Unit (CDU), Distillation Column
Rosenberg engineered and supplied 12 replacement 410S stainless steel valve trays for a 3,200 mm ID Fractionator Tower at Neste’s Porvoo Refinery in Finland, supporting the continued performance of the existing column.

Case Study

Produced Water Treatment Using DEPSEP™ Plate Pack Technology

  • Oil Water Separators, Produced Water Separation
Rosenberg’s DEPSEP™ Plate Pack Coalescer was deployed at a SASOL produced water treatment facility, providing efficient oil-water separation at a throughput of 4,000 BWPD while supporting the required treated water quality.

Field proven hardware, engineered to last

ROSEPAK perforated grooved structured packing element

ROSEPAK™ Structured Packing

  • Structured Packing
ROSEPAK™ Structured Packing uses corrugated sheet geometry to create uniform flow channels that maximise gas-liquid contact while maintaining exceptionally low pressure drop. It is ideal for vacuum distillation, close-boiling separations, and high-efficiency mass transfer applications where capacity and energy savings are critical.

DEPSEP-C corrugated plate pack coalescer

DEPSEP-F-Plate Packs

  • Coalescers
DEPSEP™ Flat Plate Packs increase the effective settling area within gravity separators, allowing oil droplets and suspended solids to separate more efficiently while reducing equipment footprint and improving throughput.

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.
