ABSTRACT:
An improvement has been found in a process for producing Bright Stock from petroleum residuum by propane deasphalting and solvent refining. The extract of solvent refining is cooled to yield an aromatics-lean secondary raffinate which is recycled to propane deasphalting. An improved yield of Bright Stock is achieved over recycling extract to propane deasphalting.
