Spent Oils Plant

Axens Offer

Usually, traditional processes in this segment can secure either high yield or high quality, but rarely both at the same time. More specifically, processes which target high-yield require clay treatment to reduce metal content resulting in the production of toxic waste. On another hand, while pursuing higher quality lube oils, traditional processes might need the use of a hydrofinishing step at the expense of lower yield.

Revivoil™ is a game changer, achieving both high quality and high yields, effectively offering a higher ROI as compared with previously mentioned traditional processes.

Re-process spent oils for the production of various grade of base oils ready to market.

The objective of propane deasphalting is to produce bright stocks for downstream treatments. In practice, residue is extracted with propane to maximize yield of deasphalted oil (DAO) with acceptable impurities and metals levels.

Revivoil™

Revivoil™ is Axens Solutions' optimum route to lube bases from spent oil. This process, developed jointly by Axens and Itelyum (formerly Viscolube Italiana SpA), goes far to put spent oil rerefining on the fast track to success. Apart from the usual problem of collecting spent oil, traditional spent oil processing has been an underachiever when it comes to quality, yields, ecology and economics.

Safe, simple and environmentally friendly, Revivoil™ technology has the ability to re-process spent oils for the production of various grade of base oils ready to market.
