Application of heavy waste oil treatment technology in atmospheric coker combined unit
With the continuous improvement of the heavy and inferior degree of crude oil,the 2#atmospheric and vacuum coking unit of a certain company has poor separation effect of electric desalted oil and water in the production and operation process,the salt water content of crude oil after removal increases,and the oil problem of electric desalted water cutting belt is prominent.When the output of heavy dirty oil is unbalanced with the amount of back refining,the dirty oil inventory continues to rise.It will adversely affect the downstream equipment and the production balance of the whole plant.Based on the actual production problems,this paper analyzes the causes of heavy dirty oil in the 2#atmospheric and vacuum coking unit,introduces the sewage oil treatment methods currently in use in the unit,and proposes the next optimization and improvement measures for the problems existing in the sewage oil back refining.
