Process packages for oil, gas and water, plus energy-transition and environmental services.
Technological solutions
Six families of solutions
Hydrocarbon processing
Hydrocarbon processing packages
From the wellhead to export, we engineer complete oil, gas and solids handling packages. Each package is designed around your reservoir fluids and operating envelope, then modularised for fast fabrication and integration on FPSOs, fixed platforms and onshore plants.
Oil processing
- Production headers / manifolds
- Test separators
- 2/3/4-phase separators
- Slug catchers / FWKOs
- Water bath heaters / heater treaters
- Electrostatic dehydration / desalting
- Crude oil sweetening
- Crude stabilisation
Gas processing
- Gas scrubbers
- Gas sweetening
- Gas dehydration
- Hydrocarbon dew pointing
- Hydrate inhibition
- Fuel gas conditioning
- N2 generation packages
- Gas wellhead packages
- Flare gas recovery
- Sulphur recovery units
Solids handling
- Wellhead desanders
- Sand flushing internals
- De-sanding hydrocyclones
- Sand wash packages
- Sludge centrifuges
Water treatment packages
Water treatment packages
Produced water, waste water and sea water each need their own treatment train. We select and size the right combination of separation, filtration and membrane technologies to meet discharge, reinjection or reuse specifications with the smallest possible footprint.
Produced water
- CPI separators
- Hydrocyclones
- Degassers / skimmers
- IGF / MIGF / CFU
- Nutshell filters
- Fine filtration
- Activated carbon filters
Waste water
- Coarse and fine filters
- Clarifiers
- Ultrafiltration
- Reverse osmosis
- Nanofiltration
- EDI
- Biological treatment: MBBR / MBR / ASP
- DAF
- Advanced oxidation
- Sludge dewatering
Sea water
- Coarse filters
- Fine filters
- Ultrafiltration
- Cartridge filters
- Deaerators
- Sulphate removal membrane units
Sea water injection
Sea water treatment for injection
We deliver complete treatment trains that turn raw sea water into injection-grade water, supplied as individual skids or as one integrated module ready for offshore installation.
Auxiliaries
- Chemical injection systems
- Clean-in-place (CIP) systems
Water & wastewater
Water and wastewater treatment
For industries and municipalities, we design plants that produce process, utility and potable water, and treat effluents up to zero liquid discharge and water reuse.
Water treatment: process, utility and potable water
- Demineralisation (DM)
- Desalination
- Clarification and filtration for potable water
- Ultrafiltration membranes
- Reverse osmosis membranes
- EDI ultra-pure water
- Disinfection: chemical treatment and UV
Wastewater treatment: municipal and industrial effluents
- Preliminary treatment
- Primary treatment
- Biological treatment
- Tertiary treatment
- Sludge treatment
- Zero liquid discharge and water reuse
