ABSTRACT:
The present invention relates to a process for the recovery of hydrocarbon oils from other heavier oils such as vacuum residua and, more particularly, to an improved process for deasphalting petroleum oils containing those asphalts. In one aspect of the invention, the process treats a solvent which has contacted the heavy oil with a gaseous antisolvent to separate effectively and usually without distillation, the solvent from the extracted oil. The deasphalted oil product typically will have low metals contaminants and enhanced MCR. Utilities or energy requirements for the process may be improved over prior art processes.
