Processes and Applications

Find us by the unit you're working on

Sour water strippers, HCl absorbers, produced water separators, molecular sieve dryers — the named duties we design and build internals for. Start from your unit and see the equipment, the case studies and the engineering behind it.

  • Rosenberg Process Technology

Amine Contactor

Sweetening sour gas with MDEA or MEA. Tray & Packing design controls both treat level and amine carryover.

Explore ➔

Amine Regenerator

Stripping acid gas back out of rich amine so the solvent returns to the contactor without degrading.

Explore ➔

Ammonia Scrubber

Removing NH₃ from vent and process gas, protecting downstream catalyst and meeting emissions limits.

Explore ➔

Caustic Scrubber

Neutralising acid gases with sodium hydroxide, designed around salting and fouling of the bed.

Explore ➔

chl

Explore ➔

Chlorine Scrubber

Emergency and process chlorine absorption into caustic — reliability under upset is the design case.

Explore ➔

CO₂ Absorber

Post-combustion capture contactors, where low pressure drop across a tall bed decides the energy penalty.

Explore ➔

Compressor Suction Scrubber

Protecting rotating machinery from slugs and fine mist, where carryover means a trip or a rebuild.

Explore ➔

Crude Distillation Unit (CDU)

Atmospheric crude towers, where a re-tray recovers throughput without touching the pressure envelope.

Explore ➔

Deaerator & Vacuum Stripper

Pulling dissolved oxygen or light ends out under vacuum, where low pressure drop is essential.

Explore ➔

Deodoriser (Edible Oils)

Steam stripping under vacuum for food-grade oils, with hygienic, low-holdup internals.

Explore ➔

Distillation Column

Separating a liquid mixture by boiling point. Tray and packing geometry decides whether it meets spec.

Explore ➔

FCC Main Fractionator

Fouling and coking service where valve and grid design decide how long a run lasts.

Explore ➔

Flare Gas Knockout

Removing liquid before the flare tip — a safety duty where reliability outranks efficiency.

Explore ➔

Gas Filtration

Explore ➔

Gas Scrubbers

Explore ➔

Glycol Regenerator

Reconcentrating TEG after gas dehydration, protecting the glycol from thermal breakdown.

Explore ➔

Glycol Still Column

Explore ➔

HCl Absorber

Recovering hydrogen chloride into water or weak acid. Corrosive duty demanding the right alloy or lining.

Explore ➔

Hydrotreater

Distributor trays, support grids and quench internals that keep the bed evenly wetted and cooled.

Explore ➔

Inlet Separator & Slug Catcher

First-stage separation on a gas plant inlet, handling surging liquid and solids without upsetting downstream.

Explore ➔

Knockout Drum

Bulk liquid removal ahead of compressors, flares and dryers. Pack sized to the real gas load.

Explore ➔

Mercury & Trace Removal

Guard beds protecting downstream catalyst and cryogenic equipment from trace poisons.

Explore ➔

MIBK Steam Stripper

Explore ➔

Molecular Sieve Dehydration

Hitting cryogenic-spec dewpoint on a gas stream. Bed support and flow distribution protect adsorbent life.

Explore ➔

Naphtha Stabilizer

Light-ends removal where flooding at the top is the classic bottleneck — usually a tray problem.

Explore ➔

Oil Water Separators

Explore ➔

Produced Water Separation

Separating a liquid mixture by boiling point — the workhorse duty of process industry, and the one where tray and packing geometry decides whether a column meets spec.

Explore ➔

PSA Hydrogen Purification

Pressure-swing adsorption for high-purity hydrogen, with vessel internals built for constant cycling.

Explore ➔

Solvent Recovery Column

Recovering and purifying process solvents in chemical, pharma and coatings plant, batch or continuous.

Explore ➔

Sour Water Stripper

Removing H₂S and ammonia from refinery sour water. Aggressive service where tray material matters most.

Explore ➔

Steam Stripper

Live or reboiled steam stripping of solvents and volatiles — MIBK, acetone, alcohols.

Explore ➔

TEG Contactor (Glycol Dehydration)

Gas drying with triethylene glycol, where mist elimination controls expensive glycol carryover.

Explore ➔

Vacuum Distillation Unit (VDU)

Deep-cut vacuum towers needing the lowest possible pressure drop across each bed.
