Book Description
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. •Addresses and demonstrates the current knowledge of the process behaviour and re-refining technology of used lubricating oils•Introduces background information on the lubrication, oil recycling industry outlining the major manufacturers and detailing their processes•Contains 94 figures and 22 tables that on results regarding the re-refining process behaviour of used lubricating oil

Book Description
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 Description
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.

Book Description
Waste Engine Oils presents a complete description of the field of engine used oils, widely collected in the networks of services-stations and garages. It describes the manufacture of base oils in refineries, and mentions the main additives playing an essential role in the quality of the marketed finished oils. The organization of the different systems of collecting in order to obtain a waste oil regenerable or used as fuel are explained. This book covers the main operations of physical and chemical treatments required in waste oil regeneration by covering the fundamental principles techniques such as vacuum distillation, solvent deasphalting, and ultrafiltration. A wide part is dedicated to applications with the description of about twenty processes. In addition, the book describes several types of energetic valorizations which concern a quite important fraction of the collected oil volume. * Comprehensive approach of the waste oil valorization * Overview of chemical engineering operations applied to waste oil * Objective view of the given information on a subject giving rise to competitiveness between the two routes of volorization

Book Description
Typically lubricants contain 90% base oil (most often petroleum fractions, called mineral oils) and less than 10% additives. Vegetable oils or synthetic liquids such as hydrogenated polyolefins, esters, silicones, fluorocarbons and many others are sometimes used as base oils. Solvent extraction is the method to eliminate the usage of high temperature or hydrogenation process in re-refining the base oil from spent lubricant oil. The main objective of this study is to recover the base oil from spent lubricants using solvent extraction method. Besides that, the effect of different solvent, the retention time and the characteristics of the extracted base oil are also determined. The raw materials that being used were spent lubricant oil and two types of solvents. These solvents are hexane mixed with potassium hydroxide in isopropyl alcohol and N-vinyl-2-pyrolidone (NNVP). During the experimental study, 200 ml of lubricant oil and 800 ml of solvents were mixed and leave to settle. After that, the mixture was filtered by vacuum pump to separate the sludge. Separation was continued using rotary evaporator to get the pure base oil. Then, the characteristics of the base oil for every mixture were analyzed. Results shows that the best solvent, is solvent 1 (Hexane + KOH + IPA) because it can recover more volume of base oil compare to solvent 2 (NNVP). Besides that, the best stirring time (retention time) for both solvent is 60 minutes. Solvent 1 is better than solvent 2 because it can recover higher volume of base oil compared to solvent 2 by 37%. As a recommendation for future work, in order to recover higher volume of base oil, the amount of potassium hydroxide (KOH) used must be increased.

Book Description
Re-refining used oil restores the chemical composition of the base oil so that it can be used to produce new lubricant products over and over again. Re-refining is an energy efficient and environmentally beneficial method for managing used oil. Instead of burning the used oil, which releases harmful emission into the atmosphere, re-refining conserves the base oil.

Book Description
This book explores effective environmental impact mitigation for petroleum-based lubricants to reduce their negative persistence during usage and upon end-of-life disposal. The book reviews the basic tribology of lubricants as well as initiatives that may enhance the environmental and economic effectiveness of lubricating oils from the composition design perspective across industries. Considering the blending, application, and disposal of petroleum lubricants in a holistic manner, the book presents and extends current best practices that minimize or eliminate adverse environmental impact throughout the product’s life cycle. The book reviews methods including: raw material substitution, minimizing oil losses during and after manufacturing, raw material and energy consumption reduction, and environmentally friendly applications of oil disposal as ways forward for cleaner and more effective production. This book provides readers with strategies for incorporating cleaner production practices into their operations – a benefit to both environmental legal compliance and business competitiveness – all the while preserving the environment for sustainable development. The book is therefore of interest to both manufacturers and consumers in the lubricants industry.
