The article shows the possibility of developing of import-substituting highly effective demulsifiers for oil dehydration. This problem requires the solution of two tasks: the creation of industrial production of reagents with high demulsifying ability and different chemical nature and the development of a method for producing composite reagents from several chemical compounds with higher efficiency. The MACROMER company has been solving the first task for many years at its own pilot production, constantly expanding the range and increasing the efficiency of the produced reagents. To solve the second task, instead of the generally accepted world practice of empirical selection of the composition of reagents to assess the effectiveness of their impact on the technological process, this work shows the possibility of selecting reagents using a special dielectric method. It has been shown that the number of reagents with demulsifying ability produced by the MACROMER company is currently sufficient to create import-substituting demulsifiers. And using of the dielectric method to determine the composition of their optimal mixtures makes it possible to develop composite demulsifiers that are insensitive to the composition of oils and are even more effective compared to imported reagents.
