The CEP difference

Specialized technology. Practical engineering.

A valuable resource deserves more than a single use. Re-refining defines the circular economy. Used oils reclaimed as virgin quality products, reducing fossil fuel consumption and CO₂ emissions.

Chemical Engineering Partners licenses its proprietary used oil re-refining technology and provides the engineering and operating knowledge needed to turn that technology into a working plant.

The CEP Process combines depoisoning, wiped film evaporation and hydrotreating with CEP-HRX™ catalyst to produce high quality base oils.

The CEP transformation

From Used Oil.
To Water-White Base Oil.

See the difference re-refining makes.

CEP technology transforms used lubricating oil into high quality API Group II base oil for new lubricant formulations.
