Analysis of Hydrodynamics of Horizontal Electric Dehydrators for Determining Ways of Intensification of Electrical Crude Oil Desalting and Dehydration

Numerical methods were used to analyze the hydrodynamic structure of flows in horizontal electric dehydrators at coil desalting plants. Based on the calculation results, new technical solutions and recommendations are proposed for improving their performance. Analysis of the velocity field in the apparatus with due regard for uniform laminar flow in its main section indicated that it is expedient to introduce crude oil (with presupplied washing water) into two tiers and to use an additional system of electrodes and sedimentation shelves. The proposed solutions ensure the most optimal flow movement in all areas of the horizontal electric dehydrator with effective use of the space of the apparatus throughout its cross section.
