摘要：

Water from water-in-crude oil emulsions is separated by chemical demulsification. Coalescence rates of water droplets have been studied in the presence of a demulsifier. Droplet size measurement was carried out by photomicrography. Fastest coalescence rate was observed during first one minute. Binary coalescence time during this period was 5.4 seconds when 50 mg/l of demulsifier was added and 4.2 seconds in the presence of 100 mg/l of demulsifier.
