From Feed to Product
A simplified view of the main processing steps from raw feed to specification product or treated water.
Raw Gas
Separation — remove free liquids
Sweetening — remove H₂S & CO₂
Dehydration — remove water
Sales GasSteps are selected for each project to suit the gas composition, operating pressure and sales-gas specification.
Separation — remove gas & free waterSteps are selected for each project to suit the feed properties and the storage or export specification.
Produced Water — separated from the wellstream
Bulk Oil Removal — hydrocyclone / CPI
Flotation — IGF / DAF
Polishing — filtration, where required
Reinjection / DisposalTreatment stages are selected for each project to suit the water quality and the reinjection or disposal requirement.
