Abstract: | Due to the increasing demand for petroleum resources and increasing exploration capability and production as well as crude oil becoming increasingly heavier and inferior both in China abroad, the refiners have to frequently change their crude oil varieties, which will have a great impact on electric desahing and dehydration units. The crude oil electric desahing and dehydration is the main crude oil pretreatment process, whose operation performances will have a direct impact on the safe, high -efficiency long - term operation of the downstream process units in the refinery. The main equipment for crude oil electric desalting and dehydration are introduced, including the electric desalting drums, types of electrodes, power supply systems and other auxiliary equipment. Some new processes and technologies of electric desalting are discussed and their technical characteristics are analyzed. The future development orientation of crude oil electric desalting and dehydration technologies are prospected. |
