Effects of Process Variables and a Comparative Study of Methods for Transfer Oil Production from Spent Engine Oil

The influence of process variables on the production of transfer oil from spent engine oil (SEO) is presented in this paper. Various methods for SEO treatment are also highlighted. Process parameters like solvent type, solvent to oil ratio, extraction temperature, adsorbent to oil ratio, adsorption time (contact time), adsorption temperature and base oil to chemical additive ratio greatly influenced regeneration of base oil from SEO using solvent extraction-adsorption method which has also been established to be more advantageous over previous methods used in this process.
