Abstract
A comparative analysis of the intensity of mixing processes and losses due to hydraulic resistance in variously designed mixers used in electrical desalting plants of oil refineries was made. The effect of the working fluid feed rate was studied to analyze the flow structure in the working space of the apparatuses and to determine the hydrodynamic conditions that are favorable for execution of the flow mixing process and that excludes formation of stagnant areas in the equipment. The obtained results of numerical simulation of velocity and pressure fields can be used at the initial stage of design of new mixers (to justify choice of the shape, size of the working area, etc.) and to determine the optimum technological conditions of the operating apparatuses for crude oil desalting and dehydration (to reduce energy and fresh water consumption).
