Title: A process for solvent refining a lubricating oil
Inventor: SEQUEIRA AVILINO JR
IPC: C10G21/28
Filed: 1981-02-12
Granted: 1984-04-23
Abstract: A lubricating oil feedstock is solvent-refined by placing it in contact with N-methyl-2-pyrrolidone (I), which selectively extracts aromatics.  This produces an extract phase rich in aromatics contg. a major amt. of (I) and a non-aromatic raffinate phase contg. a minor amt. of (I).  The improvement is that residual solvent (remaining after solvent removal by flash vaporization, distn. and/or rectification) is removed from the two phases by stripping with an inert gas, such as N2.  The resulting mixt. of inert gas and solvent vapor is then cooled to condense the solvent, and the inert gas and the solvent is recycled.
