Industrial studies for waste oil re-refining, distillation, extraction & desulfurization process.
The EPA estimates that there are 1 billion gal/y of used lubricants generated in the United States. Of this, 200 million gal/y are disposed of improperly. Additionally, it is believed that 40% of this material is poured directly into the ground [1]. These disposal methods not only pose a significant threat to local environments, but they also represent the waste of a valuable resource. I......
When we talk about engine oil, we are referring to the lubricant of the engine. The main role of the oil is to lubricate the engine to reduce wear, auxiliary cooling and cooling, sealing and leakage prevention, rust and corrosion prevention, shock absorption and buffering. Construction machinery needs to change the oil diligently to ensure the healthy operation of the equipment.Waste oil:One ......
From the above characteristics of short path distillation technology, it is clear that it has the following obvious advantages over conventional distillation technology in the actual industrial application:1, for the separation of high boiling point, heat-sensitive and peroxide material, short path distillation provides a separation method. Because short path distillation operates at temperature......
AbstractAssessment of contaminant releases during utilization of used oils is essential for the determination of environmental acceptability. These paper reports the results of the study examining a toxic metal leachability from used engine oil and sludge samples employing leaching test (TCLP). The leaching test indicated that lead in oil samples exceeded 5-ppm concentration level what qua...
ABSTRACT: Waste lubricating oil arises wherever work is carried out with lubricating oil and where it is put to use for a particular purpose. Waste lubricating oil should be collected and reused in order to decrease detrimental effects on environment, and underground and surface waters, since it pollutes the atmospheric air as a result of burning and has adverse effects on living organis...
AbstractThis paper describes an investigation carried out to study the recycling of spent engine oil as a result of indiscriminate dis-posal of the spent engine oil into the surrounding which has contributed immensely to the level of environmental pollution in our society and nation at large. This paper identify a unique method by which the spent oil is adequately recycled for re-use, the cost ...

Ⅰ. Classification of waste mineral oil technology1.Repurification process Settling, centrifugation, filtration, flocculation, one or several combined.This process is roughly equivalent to the simple regeneration in the past, and the main purpose is to remove the water in the waste oil, the mechanical impurities that are generally suspended, and the mechanical impurities that are stably disper...
Flash PointThe flash point is the lowest temperature at which a substance vaporises into a gas, which can be ignited with the introduction of an external source of fire. There are two main methods of measuring a flash point – namely, open cup and closed up.Open cup flash point testing occurs when the substance is placed into a vessel which is open to the outside atmosphere. Its temperature ...
