Abstract
A method for producing a process oil is provided in which an aromatic extract oil is added to a napthenic rich feed. The combined feed is then hydrotreated in a first hydrotreating stage to convert at least a portion of sulfur and nitrogen in the feed to hydrogen sulfide and ammonia. After stripping the feed is subjected to a second hydrotreating stage to provide a process oil.
