SOLVENT RECOVERY SYSTEM BELOW SUPERCRITICAL CONDITIONS

摘要

A system and process for solvent recovery after sonic treatment of heavy oil feedstocks is disclosed. The system avoids supercritical variations. The separation process involves solvent selection and use of a proprietary sonic reactor. The solvent recovery process may include pressure variations to solvent materials in order to obtain separation from of solvents from separated asphaltenes or deasphalted oil at high temperatures. The applied pressure variations allow the separation to occur avoiding supecritical states in the solvent materials.
