Abstract
An apparatus and method for reclaiming a useful oil product, from waste oil provides an evaporation chamber in which waste oil is heated and vaporized, preferably at a temperature which causes some cracking of the oil. Hydrogen is injected into the vaporized oil, so to cause saturation of at least some of the olefins in the vaporized oil. The vaporized oil is then condensed and recovered as a useful oil product. The apparatus operates at substantially atmospheric pressure, or a pressure only slightly above atmospheric pressure. Hydrogenation of the vaporized oil stabilizes the recovered oil, and prevents formation of tars and other heavier hydrocarbons, which can cause difficulties in use of the recovered oil.
Claims21
A method of reclaiming a useful oil product from a waste oil, the method comprising the steps of:
- (1) providing a stream of waste oil;
- (2) heating the waste oil to vaporize oil therefrom;
- (3) passing a supply line containing hydrogen through the heated waste oil to heat the hydrogen;
- (4) injecting the heated hydrogen into the vaporized oil;
- and
- (5) recovering the vaporized oil as a useful oil product.
A method of reclaiming a useful oil product from a waste oil, the method being carried out substantially at atmospheric pressure, the method comprising
- (1) continuously supplying waste oil to an evaporation chamber;
- (2) heating the waste oil in the evaporation chamber to generate oil vapors therefrom;
- (3) passing a supply line containing hydrogen through the heated waste oil to heat the hydrogen;
- (4) injecting the heated hydrogen into the vaporized oil;
- and
- (5) recovering the oil vapors as a useful oil product.
