STUDY OF THE EFFECT OF DEMULSIFIERS ON THE GROUP COMPOSITION OF TRANSPORTED AZERBAIJANI CRUDE OILS

The article presents the results of the study of oil dehydration processes in the Muradkanly, Bulla and Buzovna. The results of experiments on selection of demulsifiers for oil dehydration are presented, the choice of optimal demulsifiers, using which a representative oil sample with a residual water content of 0,1 wt % is developed, is justified.The most effective demulsifiers are selected on the basis of laboratory studies taking into account the properties of raw materials and are specified during experimental and industrial tests on the current technology. Crude oil treatment temperature is increased, light oil fractions are converted into gaseous phase, which entails increase of gas quantity, increase of oil losses from gas entrainment and decrease of commercial oil output. In the article, the application of new types of emulsifiers in the future is considered more appropriate.
