1. Introduction of Waste Oil Distillation Plant

Vacuum Pressure Distillation,is the new technology which can refine the tire oil , plastic oil , waste engine oil, sludge, motor oil and so on into base oil(which can be made into diesel and gasoline after processed by our catalyst). The oil quality is better than the original normal pressure distillation technology, which show on purity ,transparence, lightness .this technology will do deodorization and destinke process to the raw material oil automatically by "dry type" vacuum pressure distillation method. With the vacuum distillation technology, the distillation temperature is considerably reduced, and the oil output will higher 5%-10% compared with original normal pressure distillation technology. It makes more profits to the enterprise virtually.

 

2. Raw material which can be used

    a. Waste oil .example: waste diesel, waste oil residue etc.

    b. tire/rubber oil

    c. plastic oil

    d. crude oil

e. waste engine oil

f. waste motor oil

g. waste lube oil

h. waste transformer oil

i. underground oil

3. Models of waste Oil Distillation Plant


 4. Installation: We will be in charge of arranging our engineer to go to your place to guide the installation and train your workers how to operate the waste oil distillation plant ,and buyer will be in charge of the food, accommodation and round air tickets.

 

 5. Exporting Experience:

 America:

Brazil, Canada, Colombia, USA,

Middle East:

Dubai, Iran, Jordan, Saudi Arabia, Turkey

Europe:

Albania , Bosnia and Herzegovina

Asia:

Afghanistan, India, Malaysia, Pakistan, Philippines, South Korea, Vietnam, Myanmar

Africa:
