Design Aspects of Used Lubricating Oil Re-Refining

Design Aspects of Used Lubricating Oil Re-Refining presents a feasible and comprehensive technology for recycling of used lubricating oils. This book discusses efficient and effective ways of reusing lubricating oil which, if implemented, will result in a better quality of life, the stability of the environment, the health of national economies and better relationships between nations. It presents essential experimental results for process designers and engineers to establish a complete process design. The conditions and behaviour in each step in the re-refining process, (dehydration, solvent extraction, solvent stripping, and vacuum distillation) are examined in order to discover ways to recover and reuse wastes that are produced by lubricating oils.

Recommended to engineers and scientists in the oil refining industry as well as chemical engineering and industrial chemistry students as the methodologies outlined in this book will be useful in their project design, and enhance their analytical knowledge of a chemical process with respect to productivity and efficiency
