Chemical Demulsification of Oil-in-Water Emulsion from Gas Condensate Field

Produced water, also known as oily wastewater, is one of the major wastes in oil and gas industry. During hydrocarbon production, formation emulsion takes place such oil-in-water which has a huge financial effect on sector. Oil industry seeks highly effective reasonable demulsifying chemicals to separate emulsions into water crude oil. Thus, this publication, resin alkoxylate, cationic polyamine, surfactant ethylene oxide/propylene oxide (EO/PO) block copolymers are utilized resolve from condensate field. According findings preliminary screening, unique demulsifier DB was formulated by incorporating alkoxylate at an optimal weight percentage ratio. Demulsification efficiency (De) 96 % based measurement turbidity attained after treating (O/W) with dosage 7 ppm. To determine demulsifier's further, content (OiW) produced evaluated treatment DB. removal (ORe) 90% achieved reduced O/W 1008.3 ppm 97.1 within 15 minutes Furthermore, interfacial tension (IFT) Turbiscan analysis were performed further study demulsification process blank sample addition optimized At ppm, between significantly compared 24.98 mN/m 9.38 mN/m. The resulted significant increase Stability Index (TSI) value 8 indicates rate separation occurred. results IFT validate that mixed system more efficient than single system. By combining surfactants different functional groups, systems can exhibit greater surface activity surfactants.
