Selective Chemical Extraction (SCE™) is a multi-step treatment process customizable to meet desired effluent quality including oil and grease removal, pH adjustment, bacteria control, ion-specific removal, H2S stripping, VOC and semi-volatile removal, and efficient solids separation utilizing lamella clarification.
The core of SCE is ion-specific induced precipitation utilizing proprietary chemistry plans. Chemically induced reactions with targeted ions forms low solubility components. Divalent ions (Ca, Mg, Ba, Sr, SO4, CO3), trivalent ions (Fe, Al), as well as dissolved silica and boron can be economically removed by this method.
SCE is operated in United States oilfields by Gradiant Energy Services (GES) producing various grades of clean brine at low costs.
