MICROWAVE TREATMENT FOR DEWATERING OF CRUDE OIL EMULSIONS
Abstract
The results of demulsification of oil from the Zhanaozen field have been studied. As demulsifiers, nonionic surfactants of block copolymers of ethylene oxide and propylene oxide of various structure Basorol P123 and Disolvan were selected. At a temperature of 60°C, the degree of dehydration in the presence of Disolvan reached 94.2% after 60 minutes of thermostating, in the case of Basorol P123 – 54.3% after 100 minutes. The opportunity of microwave exposure using has been shown. Depending on the operating mode the increasing of temperature of the oil leads to the maximum dehydration of the oil emulsion. Increasing the microwave exposure power to 700 W showed greater efficiency for breaking down stable water-in-oil emulsions. Using the microwave exposure to the crude oil emulsion showed that the degree of dewatering in the presence of Disolvan reaches 100% after 28 seconds.
