TREATMENT OF WASTE ENGINE OIL USING OPTIMIZED

2019-12-23  This paper addresses treatment of waste engine oils (WEO) treated by acid/clay refining method using glacial acetic acid. An optimization of the process parameters in terms of settling time, stirring speed and mixing temperature of method was developed to improve the process efficiency and oil recovery. The quality of the treated WEO was evaluated in terms of viscosity index and flash point value.

Industrial- and automotive-used lubricating oils recycling ...

2020-1-13  Over the years, acid-clay process has the highest environmental risk as well as the lowest cost . The disadvantage of the acid-clay technique includes the production of large volume of acid sludge and difficulty in removing the clay sludge . However, its advantage of high-yielding oil recovery downplays on its drawbacks.

Alternative Processes

Acid Clay Treatment (not offered by CEP) In the acid clay process, used oil is typically filtered and then heated to remove debris, solid particles and water. It is then mixed with sulfuric acid which extracts metal salts, acids, aromatics, asphaltenes and other impurities. This forms a by-product of acidic sludge that settles out of the oil.

Waste lubricating oil treatment by extraction and ...

2013-3-15  Highlights Novel technology combining extraction and adsorption. 1-Butanol achieved maximum percent sludge removal. Addition of KOH accelerated the waste sedimentation process greatly. Acid activated clay gave the give best conditions for treating waste oil. The optimum solvent-adsorbent pair for spent lubricant oil recovery is 1-butanol/activated clay.

Used lubricating oil recycling using hydrocarbon solvents ...

2005-1-1  In the acid-free clay process the used oil is pretreated using two natural polymers to remove carbon sludge followed by vacuum distillation and clay treatment. However, the product oil from this process is relatively high in metals and the process needs a high percentage of clay to recover the color of the recycled oil ( Atomic Vacuum Co., 2000 ).
