Water is an important industry resource, especially in upstream operations. Process water needs to meet certain quality standards to protect equipment and maintain production levels. Produced water needs treatment to ensure regulatory compliance and/or recycling. Many operators are facing stringent limits to the levels of phosphorus, nitrogen, copper, selenium and other contaminants. Fluctuating oil and gas prices lead to frequent moves between production locations, and water treatment installations need to be more compact and mobile than ever.
Depending on the operating mode, UF is known for complete removal of all suspended solids and free/disperged/emulsified oil:
- Permeate quality is <<1 mg/ltr TSS and <<1 mg/ltr free/disperged/emulsified oil
This makes X-Flow UF technology very suitable for delivering the best feedwater quality to SRP, RO, (C)EOR, SAGD, NF and IX.
X-Flow UF technologies are available in two different operating modes:
Xiga and Aquaflex
These technologies ae well-suited for (sea)water 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. It is is known for its reduced footprint and low energy consumption.
The Crossflow technology 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 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 optimize 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.
