9,000 CMD Nano-Filtration Plant BOO — Khurais
A portable build-own-operate nanofiltration plant removing sulphate from oilfield produced water at Khurais — 9,000 m³/day, started up October 2016.
A portable nano-filtration plant removing sulphate from oilfield produced water at 9,000 m³/day, started up in October 2016. The skid-mounted design mobilizes quickly and runs under PLC with 24/7 online monitoring of flow, sulphate, SDi, turbidity, and pressure.
Designed for easy mobilisation, the skid-based plant runs under PLC with 24/7 online monitoring of flow, sulphate, SDi, turbidity, and pressure — using 10- and 5-micron cartridge pre-filters ahead of nanofiltration membranes in 6-inch, 7-element pressure vessels.
Oilfield produced water needs sulphate removed before reuse, and the solution had to be portable enough to mobilise quickly to the Khurais site, 250 km southwest of Dhahran.
- Sulphate removal from produced water
- Portable / fast mobilisation
- Remote site (250 km SW of Dhahran)
A treatment train sequenced to the contaminants.
Cartridge pre-filtration (10 then 5 micron) protects the membranes; high-pressure pumps feed nanofiltration membranes housed in 6-inch, 7-element pressure vessels; PLC and VFD control with field instrumentation (flow, sulphate, SDi, turbidity, pressure) runs it unattended.
