The Application of New Separation Technology - Molecular Distillation Regenerated of Waste Heavy Oil

Abstract:

The new technology of thin film evaporation - molecular distillation was introduced to the regeneration process of waste heavy oil. According to the results, this method was proved to be effective to the narrow separation of the material of waste engine oil from engine maintenance workshop, and also be suitable to a large-scale production. The properties of the distillation products from molecular distillation were found to be comparable with those of the typical standards of MVI250 and MVI350 respectively. The overall yield of 90% was got in the process. The recommended conditions of the pabs was 5-80 pa, heat transfer oils was 200-240oC, circulating water temperature is 25-28oC. The resulted product can meet the standards of MVI250, MVI 350.The practice shown in this paper suggested a good method to get high yield of good base oils. The molecular distillation will show excellent prospects in the field of waste oil regeneration.
