Abstract
Solvent extraction separation process is widely used in art of petrochemical engineering which provides a method for clean oil production. In this paper, the development of solvent extraction separation process has been described, such as aromatics extraction process, solvent extraction desulfurization process, and critical components oriented separation process. The advantage of solvent extraction separation in the process of oil refining was carefully discussed. Finally, a prospect about the development of solvent extraction separation process was introduced, considering the social problem of the conversion of olefin in the production of China standard VI gasoline and the adjustment of product mix of gasoline.
