Executive summary

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.

The challenge

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.

Site & process constraints
  • Sulphate removal from produced water
  • Portable / fast mobilisation
  • Remote site (250 km SW of Dhahran)
Engineering approach

A treatment train sequenced to the contaminants.

Cartridge Filtration (10 & 5 µm) → HP Pumps → Pressure Vessels → Nano-Filtration Membranes

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.

Skid-mounted, portable: built for fast mobilisation to a remote oilfield site.
