Re-refining used petroleum based fluids |
| abstract |
A method for separating a lubrication oil from a waste fluid includes separating water from the waste fluid including a lubrication oil by heating the waste fluid while sealed in a first vacuum chamber to a first maximum specified temperature and first specified pressure. Fuel oil is separated from a fluid received from the first vacuum chamber by heating the fluid while sealed in a second vacuum chamber to a second maximum specified temperature that his higher than the first maximum specified temperature and at a second specified pressure. Finally, the lubrication oil is separated from a fluid received from the second vacuum chamber by heating the fluid received from the second vacuum chamber while sealed in a third vacuum chamber to a third maximum specified temperature that his higher than the second maximum specified temperature and at a third specified pressure. The first, second and third pressures need not be different. |
