Environmental friendly used engine oil recycling machine / waste oil to base oil distillation plant

The main technology of waste oil regeneration in abroad is Kleen,Meinken,IFP,KTI,Snamprogetti,DOH,DCH,BERC and Recyclon.etc.New processes that have been applied abroad include ultrafiltration, centrifugal separation, molecular distillation, flocculation, solvent refining, etc.In the late 1980s, two regeneration processes were developed in China.One is distillation-extraction-clay process, which uses ethanol as solvent for extraction; the other is high temperature clay process, which combines distillation and clay treatment in the same process.Recent thin film evaporator - furfural refining-clay process can extract more base oil fractions than conventional vacuum distillation, furfural has better extraction effect than ethanol, and the yield of base oil is higher.
According to the deterioration mechanism and degree of lubricating oil, the regeneration technology of waste engine oil can be divided into re-purification process, fine refining process and re-refining process.

2.Technology of our company

1) Process flow description

 The process of waste oil reduction and regeneration base oil is introduced as follows: Our company specializes in the production of waste oil regeneration equipment and process research and development for more than ten years, and constantly explores and improves the technology. Combining with the advantages and disadvantages of the current equipment process, we focus on the materials in the process of waste oil processing equipment, which are easy to coke at high temperature, have high operating cost and have many potential safety hazards. The problem of high overhaul rate and high technical difficulty has been discussed and studied, and a lot of manpower and material resources have been invested. Through repeated testing and continuous improvement, the problem of easy coking of materials at high temperature has been successfully solved.
