摘要
Complete conversion of resid into light oil needs to consume large amount of hydrogen, because the light oil has higher hydrogen content. The conversion of whole resid into light oil is not economic at the normal price gap between the light and heavy oils. Hence a combination of hydrogenation process with carbon removal process is generally adopted.The heavy solvent deasphalting can selectively remove the asphaltenes and metals contained in resid while providing a large amount of easily convertible deasphalted oil for the down-stream processes.This article refers to the characteristics of heavy solvent deasphalting and its application in sour resid processing, along with various routes for utilization of deoiled asphalt.
