Selection and project requirements
Equipment selection considers capacity, separation performance, pressure drop and fouling resistance under the specified operating conditions. Engineering support can include hydraulic design, assessment of existing internals, revamp recommendations, and installation supervision, with the scope agreed to suit project requirements.
Process performance guarantees can be offered for selected applications, subject to agreed feed characteristics, operating conditions, and performance criteria.
Where Evergreen sits in a refinery
Selected refinery applications
Crude Distillation Unit
Atmospheric separation of crude oil into light gases, naphtha, kerosene, gas oils and atmospheric residue. Trays, structured packings and column internals serve the fractionation, stripping, pump-around and side-draw sections, selected to suit the duty.
- EVERFRAC trays
- EVERPACK structured packings
- EVERGREEN column internals
Vacuum Distillation Unit
Separation of atmospheric residue under vacuum to recover vacuum gas oils while limiting thermal cracking. Packings and column internals are selected for low pressure drop, effective liquid distribution and the requirements of each fractionation or wash section.
- EVERPACK packings
- EVERGREEN column internals
FCC Main Fractionator
Separation of FCC reactor vapours into lighter products, cycle oils and slurry oil. Trays and column internals are selected for fractionation and pump-around duties, with consideration for catalyst carry-over, fouling and operating loads.
- EVERFRAC trays
- Baffle / shower trays
- EVERGREEN column internals
Hydrocracker Fractionators
Fractionation of hydrocracker products to recover naphtha, kerosene, diesel and heavier fractions. Trays, packings, and column internals are selected to suit the operating conditions and required separation.
- EVERFRAC trays
- EVERPACK packings
- EVERGREEN column internals
Coker Main Fractionator
Fractionation of vapours from coke drums to recover naphtha and gas oils. Internals for wash and fractionation sections are selected with consideration for coke carry-over, fouling and operating loads.
- EVERFRAC trays
- Baffle / shower trays
- EVERGREEN column internals
Amine Absorbers & Regenerators
Removal of hydrogen sulphide and, where required, carbon dioxide from refinery gas streams using amine solutions. Trays, packings, and column internals support gas–liquid contact in absorbers and solvent regeneration in regenerators.
- EVERFRAC trays
- EVERPACK packings
- EVERGREEN column internals
Sour Water Stripper
Removal of hydrogen sulphide and ammonia from refinery sour water. Trays and column internals are selected to suit the stripping duty, with consideration for fouling, corrosion and operating upsets.
- EVERFRAC trays
- EVERGREEN column internals
