Improve the method of waste oil regeneration while respecting different environmental aspects.

摘要

The present invention relates to different methods of recycling lubricating oil. This document describes the improvement actions taken to improve the recovery rate and to deal with the various emissions generated in the different steps of the method. According to the invention, a second evaporator connected to a fractionator is installed,Due to the proper and proportionate addition of strong alkali fillers and the use of chemical resistant materials after preheating, the production unit maintains stability and continuous operation, and the product recovery rate is significantly improved. end these ones hereAfter improvement, the average recovery increased from 84% in the old process to 95% in the new process. This improvement led to a substantial increase in the output and quality of finished products. This improvement also extends the panel for treating used oil. in additionThe gases produced in this method, which are mainly composed of volatile organic compounds, are distorted or treated in the biofilter. In the case of dehydration, dehydration is removed in an aerobic membrane bioreactor in the presence of microbial consortia capable of degrading phenolic compounds and hydrocarbons.
