Abstract
A quantitative assessment and identification of organochlorine compounds present in the oil directed for processing was performed, and an effective method for their extraction was proposed. It is shown that feeding an aqueous alkaline solution for mixing with processed oil before it enters the electrical desalting unit at the maximum admissible temperature in the electrical dehydrators (135 ° C) allows reducing the content of organochlorine compounds from 6 to 1 ppm.
