Process for making non-carcinogenic, high aromatic process oil |
(57) An atmospheric distillate or a vacuum distillate stream is combined with a calculated
amount of lubricant extract stream. This well-mixed stream is then hydrotreated to
yield a non-carcinogenic, high aromatic process oil. A desired level of high aromatic
lubricant product streams and having the desired solvency properties is achieved by
varying the feed stream ratio and hydrotreating conditions.
