The used lubricating oil vacuum distillation device designed by our company has the following characteristics: With high vacuum distillation method, the base oil components can be distilled at 340 C, which is far lower than the current popular domestic used oil vacuum distillation of 380-400 C, which effectively avoids base oil molecules cracking at high temperature , reducing production of light oil like naphtha, improves the quality and yield of base oils, and decreases risk of plant operation. Using automatic continuous operation, during normal operation, only one person per shift can complete the control. The heating system adopts electromagnetic heating, no open flame, and high safety. The plant runs with low energy consumption, processing every ton of used oil, and the energy consumption required for heating is only about 200,000 kcal. Modular design, the on-site installation and commissioning cycle is greatly shortened. For the daily processing capacity of less than 20 tons, the whole set of equipment including heating, heat exchange, condensation, vacuum, atmospheric distillation, vacuum distillation, refining, compounding, control, circulating pool, cooling water tower, operating platform, etc. It can be transported by a truck. Small footprint. Taking the processing capacity of 10 tons/day as an example, the overall area of the device is only 28 square meters (4 meters x 7 meters). Quality of the product is good, and quality of the product produced has been tested by quality inspection department and meets the new lubricating oil quality standard.
