During vigorous testing, Crystal has purified oily water down to below 1 ppm. The separators have a filter-less operation with no internal moving parts, which enables continuous operation for many years requiring no downtime for maintenance and/or cleanings. The separators also were designed to run 24 hours a day in the harshest environments. With an ultracompact footprint, Crystal is customizable and can be used in a wide range of applications such as oil fields, oil platforms, ship bilges, sand washing plants, wastewater treatment plants and salt mines. Sulfate remover improves oil recovery GE's Water & Process Technologies recently released the new SeaWater Sulfate Reducing (SWSR) membrane to remove sulfate from injection water for offshore oil pro- duction. The SWSR membrane removes sulfate to reduce scale and corrosion in the injection well, which can reduce oil recovery and plug the well. The prod- uct also has fouling resistance due to its three-layer mem- brane design and smooth surface. The SWSR membrane series is an advance- ment of GE's DK series nanofiltration membrane and provides a high transmission of sodium chlo- ride into the permeate water to minimize operating pressures. The membrane offers a physical barrier for any suspended particles including bacteria, pyrogens and colloids. Additionally, the new mem- brane will help prevent strontium and barium sul- fate scale in injection wells and will better mitigate well souring by reducing sulfate. Treatment for oily water process needs When a coastal LNG project required oil/water separators to meet the harsh environment and stringent requirements of the end user, Hydrasep delivered its water treatment services despite seis- mic, hurricane force winds, freezing tempera- tures, high sediment content and customization. Hydrasep offers services for all oily water process treatment needs. The company will help operators treat their fracture flowback and produced water onsite and in-line. Hydrasep also will help lower operating cost, lower downstream process upsets, filtering needs and chemicals consumption. The company will work to lower water reuse and recy- cling cost, and the oil recovered with a Hydrasep is pipeline quality. Water evaporator runs on field gas HydroFlare by Hydrozonix is a new produced water evaporator that runs on field gas. The patent-pend- ing HydroFlare helps resolve produced water dis- posal capacity concerns either due to increasing produced water volumes, capacity restrictions due to induced seismicity or increasing disposal cost for remote wells. The evaporator can be a permanent installation or a portable device that can be relocated from area to area. Besides produced water evapora- tion, HydroFlare can be used as an alternative to collecting field gas under Quad O(a).
