Experimental regeneration process of used motor oils

Abstract

The present work, on an experimental basis, consists of an analysis and treatment of used motor oil (used oil collected by NAFTAL stored at the port of Algiers). For this, we carried out tests in the laboratory in order to develop an adequate re-refining process. First we made a comparative analysis between the sample taken from a storage tank and a new engine oil produced in the Arzew refinery. The results of these analysis allowed us to identify the different stages of the process of regeneration (Pre-treatment, metal removal by a chemical agent, a finishing treatment by passage through the bentonite and filtration). This process has enabled us to eliminate most of the impurities and the optimization of different parameters, the engine oil obtained at the end of the process is a basic oil ready to be used again.
