challenges in the oil & gas industry
- Disposal or re-use of oily wastewater at refineries
- Desalination of seawater for drinking water or process water
- Disposal or re-use of produced water
- Seawater injection
- SAGD and boiler feed water
- Low-salinity water injection and ion exchange
- Cooling and process water
- (C)EOR and IOR
- Seawater sulfate removal (SRP)
- Reverse osmosis (RO)
Handling water in the oil & gas industry is more than treatment alone: pumps, pipes, pressure vessels, instruments and controls are also needed to get a desired water quality.
Specifically for the oil & gas industry, X-Flow has innovative ultrafiltration membrane solutions to reduce footprint, chemical consumption and life cycle costs, which are increasingly important for offshore applications.

applications
- Permeate quality is <<1 mg/ltr TSS and <<1 mg/ltr free/disperged/emulsified oil
This makes X-Flow UF membrane technology very suitable for delivering the best feedwater quality to SRP, RO, (C)EOR, SAGD, NF and IX.
X-Flow UF membranes are available in two different operating modes:
The dead-end operation mode is well-suited for (sea)water applications where the feed has an oil content of less than 5 mg/ltr and a Total Suspended Solilds (TSS) of less than 30-50 mg/ltr. Dead-end filtration is known for its reduced footprint and low energy consumption.
Crossflow filtration
Crossflow operation is better suited for much higher TSS concentrations (<200 mg/ltr) in the feedwater combined with an oil content of less than 1000 mg/ltr. Crossflow filtration is known for its reduced chemical consumption and concentrating the oil fraction 10 to 20 times.
Two featured applications
Refinery cooling tower feed
Refinery cooling tower feed systems that use RO permeate for boiler feed and the softened RO concentration for cooling tower make up in order to optiize the water use efficiency of these processes.
Produced water advanced water treatment
Remove all remaining oil and solids after secondary produced water treatment in order for the effluent to be directly used in an EOR, SAGD or other production process application.
Rig and FPSO ion specific, chemical free, and low energy sulfate removing membrane barrier that optimizes the cost effective EOR reinjection process offshore.
