The DIR series waste lubricating oil regeneration and distillation equipment from Chongqing Tongrui Filtration Equipment Manufacturing Co., Ltd. is a comprehensive processing system designed for the resource recovery of waste mineral oils. Distinct from traditional sulfuric acid distillation or catalytic hydrogenation methods, this system utilizes proprietary composite catalysis and high-vacuum distillation technologies to achieve the environmentally safe regeneration of various waste lubricants, including engine oil, gear oil, and hydraulic oil.
The operational process begins with the pretreatment of waste oil to remove large impurities, followed by its entry into a catalytic reaction vessel. Here, a specialized composite catalyst is used to passivate and polymerize harmful components such as gums, asphaltenes, and oxides. The material is then fed into a high-vacuum distillation system, where temperature-controlled fractionation separates the oil into distinct fractions. Multi-stage condensation yields high-quality regenerated base oil characterized by stable color and the absence of unpleasant odors. Distillation residues can be utilized as fuel, and the process ensures the harmless treatment of exhaust gases, thereby eliminating the risk of secondary pollution.
This system features a high degree of automation, excellent oil recovery rates, and controllable energy consumption. It is ideally suited for small-to-medium-sized waste oil recycling enterprises and supporting projects for refineries, balancing environmental compliance with economic profitability to provide global clients with a complete solution for waste oil recycling.
