The chapter presents several physical and chemical processes employed for reclamation, re-refining, and reprocessing of used lubricating oils. The earliest process is known as the acid–clay treatment process involving the mixing of the used oil with 93 to 98% sulfuric acid.
Sulfuric Acid Treatment Processes to recover, purify, concentrate or dilute sulfuric acid. Sulfuric acid is one of the world's most widely used chemicals. It finds numerous applications as in the production of fertilizers, explosives, plastic (polyurethanes), esterification of intermediates, dyes and also within the iron and steel industries.
EFFECTS OF ACID TYPES ON THE RECYCLING OF USED LUBRICATING OIL NOTE: This is not a project, but a very rich paper written by practitioners in the field Department: Engineering – Chemical Engineering Abstract This study focused on the effects of acid types on the recycling of used lubricating oil.

May 27, 2020· The advantage of using the acetic acid is that it does not react with base oils. The recycling process takes place at room temperature. The recycling process started with removing the contamination from the used engine oil. Glacial acetic acid was mixed with the used engine oil using a ratio of 0.8 mL acetic acid to 10 mL used engine oil.
This research investigated the effect of three different acids (sulphuric acid, hydrochloric acid and nitric acid), on three different clay deposit samples, to recycle used lubricating oil. To achieve this objective, filtration of the used oil was carried out first to remove impurities like: sand, metal chip and other micro impurities using: Buncher funnel, filter papers and vacuum pump. The ...
Albeit these methods effectively removed contaminants from used lubricating base oil and returned the oil to a quality essentially equivalent to oils produced by fresh lube oil stocks, acid treatment method is much cheaper to apply (Rashid et al., 2013). According to this author, the main drawbacks of this method is high acid value of sludge ...
Jan 01, 1979· Acid treatment of diluted oil Although re-refining with sulphuric acid has been widely used, the use of hydrocarbon diluents in conjunction with acid treatment has not been reported. This is surprising in view of the fact that it has been established practice to employ solvents with viscous oils prior to acid treatments [2J .
We claim: 1. In a process for the refining of used lubricating oils by alkaline treatment of the oil or of its crude raffinate at a temperature from 200° to 500° C. as well as further reprocessing, the improvement wherein the oil is treated with 0.5 to 10% by weight of an alkali metal hydroxide mixture of 20 to 70 parts by weight of potassium hydroxide and 30 to 80 parts by weight of sodium ...
Jan 13, 2020· Acid Clay Treatment. 1. The used lubricating oil sample collected from the same source is treated using acetic acid and kaolinite for treatment purposes. After filtering is done in the above method, the used oil sample is poured into a clean beaker (100 ml of oil sample is used). 2.
A method for purifying used oil without the use of hydrogen comprising contacting a demetallized used oil with an acid such as sulfuric acid and an adsorbent such as clay. Reclaiming used lubricating oil - Phillips Petroleum Company
Recycling Used Lubricating Oil Using Untreated, Activated and Calcined Clay Methods 1JD. Udonne, ... use of toxic materials such as sulfuric acid. These ... have high sulfurlevels. The adsorption treatment of waste lube oil is based on the ability of adsorbent to …
Analogously to example 1, only clean lubricating engine oil at a ratio of silica gel:sulfuric acid 1:of 0.25, 1:0.5 to 200 and 150°, respectively. The results are presented in the table. Examples 7, 8. Analogously to example 1, only clean lubricating engine oil, and as an adsorbent, a mixture of silica gel and sand what you presented in the table.
Dec 01, 2018· This research investigated the effect of three different acids (sulphuric acid, hydrochloric acid and nitric acid), on three different clay deposit samples, to recycle used lubricating oil.
Jan 06, 2017· HOW TO RECYCLE LUBRICATING OIL. Lubricant is a viscous liquid used to lubricate the moving parts of an engine and a machine. In general, after the removal of impurities, resin and asphalting, polycyclic aromatic hydrocarbons, wax in crude oil, the lubricating oil is produced.However, since crude oil is limited, the crude oil reserves are drastically reduced worldwide, thus, the recovery …
The acetic acid has shown a high reactivity with the contaminants in the used oil, and columns 5 and 8 show the base oil results from treatment with sulfuric acid and acetic acid, respectively. It is obvious that the base oil resulting from acetic acid treatment is brighter and has a clear yellowish color.
A two-phase study was made to establish properties of waste lubricating (used automotive crankcase) oils and to develop ecologically and economically sound methods for their disposal. Of particular interest was the possibility of using the oils as additions to refinery feedstocks or for blends with ...
Oct 01, 2020· Regeneration of used engine oil could be seen as the process of using sulphonating agents, such as sulphuric acid, oleum or sulphuric trioxide to remove impurities from the oil (Isah et al., 2013). This process guards our environment from the toxic effects of releasing this spent lubricant into it ( Adebayo et al., 2004 ).
Used lubricating oils, particularly those containing additives such as V. I. improvers, dispersants and the like, are reclaimed by a preliminary treat with a C 4 to C 5 aliphatic alcohol, which causes the separation of a layer of sludge which contains polar additives and oxidation products. The desludged oil is then subjected to conventional lubricating oil refining steps such as treatment ...
