Role of Solvent Deasphalting in the Modern Oil Refining Practice and Trends in the Process Development

Abstract

Various implementations and various combinations of solvent deasphalting with the modern processes of deep oil refining are considered, and the ways of processing the separation products formed are demonstrated. Specific features of the main technologies used in Russia and other countries are discussed. Particular attention is paid to perspective technologies implementing the fuel direction of the process using both traditional hydrocarbon solvents and nontraditional solvents such as organic carbonates and carbon dioxide.
