Laboratory studies of highly efficient compositions

Decomposition of stable oil-water emulsions is considered an important part of oil preparation for transportation. Therefore, the issue of developing new demulsifying compositions in order to increase the efficiency of the process of decomposition of stable water-oil emulsions remains relevant. This paper presents the results of studies of the processes of dehydration of stable oil emulsions of the Muradkhanly field at a water cut rate of 52% (mass.). Laboratory studies on the dehydration of Muradkhanly oil were carried out using composition demulsifiers. The composition was prepared on the basis of Disulfan 4411, Disulfan and Alkan-415, which were used to transport oil in the Muradkhanly field during laboratory tests of the effectiveness of demulsification. Analyzing the parameters monitored in the course of laboratory tests of stable water-oil emulsions of the Muradkhanly field, the dynamics of water separation compared to the base reagent, the best results in terms of the degree of residual dehydration of oil phases at 70C were shown by the composition Dissolvan-4411+ Alkan 415 = 2:1.
