REGENERATION OF USED PETROLEUM-BASED LUBRICANTS AND ....

...BIOLUBRICANTS BY A NOVEL GREEN AND SUSTAINABLE TECHNOLOGYBy: Willian Fan, Ph.D. Candidate in Environmental EngineeringCommittee Chair, Professor Massoud PirbazariAbstract:Lubricants, either mineral-based or synthetic made, are the products derived from petroleum and developed through tribological research. Lubricants are also the essential elements for almost all modern industries.However, lubricants require change after long service because the various impurities generated from the operation may degrade the efficiency of lubricants and significantly contaminate lubricants.Many studies have confirmed that used petroleum-based lubricants collected from oil-exchange are slow in degradation and highly toxic to human health, fauna, and flora. However, hydrocarbon compounds in used lubricants can be regenerated into either lubricant base materials or an energy source. The regeneration of used lubricants has enormous benefits, including minimizing hazards, reducing waste, protecting the environment, and conserving enegy resources.The potential of the newly developed binary solvent process in used lubricants regeneration is discussed and reviewed. The binary solvent process has been demonstrated to be a promising green technology capable of removing up to 93% of impurities while recovering up to 99 % of hydrocarbon compounds from various types of used lubricants under atmospheric pressure and at a relatively low temperature. The Cold-Stage Energy Conversion (CSEC) system is built based on the concept of the binary solvent process and capable of regenerating used lubricants in a continuous-flow fashion at relatively low temperature and pressure.
