Chemical Engineering Partners is a process technology company offering a range of products and services for re-refining of waste / used lubricating oils.
Re-refining is the term used to describe use of chemical process technology to extract the lubricating base stock from waste lubricants. Water, fuel oil, additives and sludge are separated from the base stock. The Acid clay process is the known and established re-refining process. This process is inexpensive to install, but not necessarily inexpensive to operate when compared with alternatives. The quality and yield of final product are also in the need of improvement. Its waste by-products have made this process infeasible. In fact, in most Western countries it is now banned.
CEP’s technology for re-refining is based on vacuum distillation (using Wipe Film Evaporation) and hydro-treating (also known as hydro-finishing). This is the most successful acid-free commercial method of re-refining. What’s more, CEP’s complete process treats used oil to produce base oil, which meets API Group II specifications.
The proprietary CEP Re-refining Process is a six-step procedure consisting of:
- Pre-treatment
- Water and Light Fraction Removal
- Fuel Oil Fraction Removal
- Separation of Lube by Distillation
- Conversion of Lube Distillate through Hydro-treatment to Base Stock
- Splitting of Base Stock into Desired Cuts through Fractionation.
Compared to making lube oil from crude oil, it takes only half as much energy to make it from used oil with the CEP Re-Refining process, while the lube oil produced is of equal or better quality, and the carbon footprint from this process is even less.
