OSTI ID:7290936
;
In the process of treating oil, the oil is heated in the still having its bottom covered with a heavy inert material fusible but not evaporable at temperatures required and passing a permanent neutral gas therethrough. The resultant mixture of vapors and gas is passed upwardly through a filtering material which has the effect of Fuller's earth in removing color and bituminous matter therefrom, and then the vapors are condensed. The filtering material is maintained at a lower temperature than the oil.
