Available in PDF, EPUB and Kindle. Book excerpt: Used lubricating oil is a valuable resource. However, it must be re-refined mainly due to the accumulation of physical and chemical contaminants in the oil during service. Refining Used Lubricating Oils describes the properties of used lubricating oils and presents ways these materials can be re-refined and converted into useful lubricants as well as other products. It provides an up-to-date review of most of the processes for used lubricating oil refining that have been proposed or implemented in different parts of the world, and addresses feasibility and criteria for selecting a particular process. The book begins with an overview of lubricating oil manufacturing, both petroleum-based and synthetic-based. It reviews the types and properties of lubricating oils and discusses the characteristics and potential of used lubricating oils. The authors describe the basic steps of used oil treatment including dehydration, distillation or solvent extraction, and finishing. They explore the combustion of used oil for use as fuel, covering chemistry and equipment, fuel oil properties, and combustion emissions. The book considers alternative processing options such as refinery processing and re-refining. It also reviews the major refining processes that have been suggested over the years for used oil. These include acid/clay, simple distillation, combinations of distillation and hydrogenation, solvent extraction, filtration, and coking processes. The book addresses economic, life cycle assessment, and other criteria for evaluating the attractiveness of an oil recycling project, examining various costs and presenting an economic evaluation method using an Excel spreadsheet that can be downloaded from the publisher’s website. The book concludes with a chapter offering insights on how to choose the most suitable process technology.

Book excerpt: Used lubricating oil is a valuable resource, but it can be an environmental problem and a financial liability if improperly disposed of. Used oils pose hazards to human health and the environment, and therefore need to be managed safely. The mismanagement of used oil can contaminate air, water and soil. The objective of this work is to investigate the re-refining of used lubricating oils using solvent extraction process. The characteristics of used lubricating oils, utilization methods, elimination methods, environmental and human health effects were reviewed. Also, the various re-refining processes were described and a comparison between them was made to indicate the advantages and disadvantages of solvent extraction process. Experiments were carried out on used oils collected from several service stations. Used oils were subjected to preliminary treatment to remove water and dust followed by solvent extraction of base oil using different classes of solvents including alcohols, ketones and hydrocarbon solvents. Bench scale study was carried out to investigate the effect of different variables.

Download or read book Feasibility of Department of Defense Used Lubricating Oil Re refining written by John W. Kubarewicz and published by . This book was released on 1983 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense (DOD) annually procures and uses a large amount of lubricating oil in its vehicle fleets. This results in a significant volume of used lubricating oil being generated at DOD installations. Characteristics of this used lubricating oil can lead to its consideration as a hazardous waste. While Federal regulations classifying used oil as a hazardous waste have not been promulgated, this is expected to change in late 1983 or early 1984. Several states have already classified used oil as a hazardous waste in advance of Federal action. One significant option for the disposal of used lubricating oil is recovery and re-refining to produce a product capable of meeting military specifications (mil specs) for lubricating oil. The objective of this study was to determine the feasibility of capture and re-refining of all DOD used lubricating oil. The quantities of virgin oil currently procured and the capture potential are examined as is the degree of technical sophistication available in the re-refining industry. A mathematical model involving the costs of transport and re-refining of used oil and backhauling the re-refined product was developed and exercised on the available data. Results indicate that capture and re-refining of DOD's used lubricating oil is feasible under selected conditions with the cost of transportation being a major factor. The re-refining industry has both the capacity and the technical sophistication to produce a re-refined oil capable of meeting military specifications.
Download or read book Process for Preparing Lubricating Oil from Used Waste Lubricating Oil written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A re-refining process is described by which high-quality finished lubricating oils are prepared from used waste lubricating and crankcase oils. The used oils are stripped of water and low-boiling contaminants by vacuum distillation and then dissolved in a solvent of 1-butanol, 2-propanol and methylethyl ketone, which precipitates a sludge containing most of the solid and liquid contaminants, unspent additives, and oxidation products present in the used oil. After separating the purified oil-solvent mixture from the sludge and recovering the solvent for recycling, the purified oil is preferably fractional vacuum-distilled, forming lubricating oil distillate fractions which are then decolorized and deodorized to prepare blending stocks. The blending stocks are blended to obtain a lubricating oil base of appropriate viscosity before being mixed with an appropriate additive package to form the finished lubricating oil product.

Book excerpt: This report assesses the potential impact of re-refining used automotive and industrial lubricating oils on the national petroleum consumption. The technical base for this assessment is derived from a comprehensive review of the processes utilized in re-refining used oil and those processes used to produce lube oil from crude. Both existing and recently proposed processes are considered. Additionally, an extensive review of processes described in the patent literature is provided. Re-refining processes are surveyed and evaluated. Process descriptions are provided; hardware is identified; and process energy and economic requirements are calculated. Factors affecting the profitability of a re-refining operation are discussed. Economic projections of the demand for lube oil and the ability to satisfy this demand from crude oil are made and the value of lube oil as a vital resource and the need for conservation are addressed. Other factors related to re-refining are discussed, including lube oil characteristics, degradation, lube oil quality and engine sequence testing, and legislative and institutional barriers. Finally, an energy assessment of used oil utilization is made. Two options are considered in this assessment: (1) all used oil is re-refined and recycled back to lube oil; (2) all used oil is burned to recover its heat content.
