The new technology of multi-stage molecular distillation is introduced for waste oil regeneration process,in which the precise distills of base oil is studied.It is proved to be effective by experiment with the material of waste engine oil from engine maintenance workshop,also successfully applied in the waste oil regeneration plant of Petroleum Products Company-Saudi Arabia with the treatment capacity of 30 kt/a.The cut from different molecular distillation stages is found to be comparable with typical standards of MVI100、MVI250 and MVI350,respectively,and the overall yield of 92.1% is got in the process.The practice shows that a sound method to get a high yield of good base oils proves to be reliable.It enhances the industrial application in waste oil regeneration with molecular distillation.
