Oilfield Demulsifier SP-169
Demulsifier SP-169 is a classic alkylphenol ethoxylate-based oilfield demulsifier with proven track record in crude oil dehydration worldwide. It effectively breaks water-in-oil emulsions in a wide range of crude types at dosages of 10–100 ppm, delivering residual water below 0.3% and residual oil-in-water below 50 ppm. SP-169 is frequently used as a reference compound and blend component in demulsifier formulation.
