Definitions
- the object of my invention is to so treat used oil, especially crank case lubricating oil, as to remove the impurities, particularly carbon, therefrom and restore the oil to its originally uncontaminated condition.
- the invention is applicable to the purification of lubricating oil whether or not it contains gasolene, although the procedure, where it is necessary to remove gasolene as well as carbon, is somewhat modified. I shall first describe the process as used when it is desired to remove carbon and not gasolene.
- soda ash or soda ash and salt
- the separation may be efiected, with less thoroughness and rapidity, by gravity.
- oil .to be purified contains gasolene
- Ature reaches 200 to 208 F. This distils off the gasolene and also supplies the heat required during the subsequent operations of adding a saponifiable oil, an alkaline solution, and an anti-emulsion agent, which other steps are carried on as hereinbefore described.
- the process of purifying oiD, such as crank case lubricating oil, by removing therefrom impurities, such as carbon which comprises adding to the dirty oil a saponifiable oil which is miscible with the oil to be purified, then adding an alkali adapted to saponify the saponifiable oil and form a counter colloid to take up the suspended .colloidal carbon, and separating the lubricating oil from the other and heavier constituents.
- Th'eprocess of purifying oil such as crank case lubricating oil, by removing separating the lubricating oil from the other and heavier constituents.
