Waste lubricating oil regeneration goes through several steps

1. The simple refining phase
In 1970s and 1980s, some state-owned or collective enterprise collected their waste lubrication oil to recyle itby a simple refining process for their own use. It includes filtration, sedimentation or acid-bases treatment.

2.Simple distillation+Refining
In 1990s, Chinese enterprises start to use simple distillation and refining for oil reuse. The simple distillation is to vacuumize by water and steam. The vacuum degree can reach at thousands Pa at maximum, even ten thousands Pa. It's workable way if the used oil condition is not so bad. However, along with the varieties increase of lubrication additives, the simple distillation cannot produce the qualified oil and has limitation. The initial refining process is acid-bases treatment and then high temperature white clay refining and the solvent refining.

3 High vacuum distillation-complex refining
With the development of the vacuum technology, high vacuum unit technology's maturity, people start to use high vacuum technique.
