short path distiller for used lubrication oil recycling

Product Description

  Operation Principle:

Molecular distillation is a special liquid-liquid separation technology, which is different from the separation principle of traditional distillation depending on boiling point difference. It is depending on the difference of molecular mean free path to separate different matters. Here, molecular mean free path (λ) refers to the path between a molecule strikes two times. 

When the mixture of liquid flows along the heating board and is heated, light and heavy molecule will leave the surface of liquid and enter the vapor phase. Light and heavy molecule will have different moving distance when they are in vapor phase because they have different mean free path. Supposing that we put a condensation board at the proper position, light molecule can reach the board and will be condensed, then be discharged along the condensation board; while the heavy molecule will not reach the board and be discharged along the heating board. Therefore, the objective of separation has been reached.  

Technological advantages of our molecular distillation equipment:

1. Control the temperature of heating body by adopting our own thermal superconducting technology. The temperature control accuracy can be 0.5°C.

2.The equipment has a small size, simple piping, short stating time and is easy to operate. The energy consumption of our equipment is reduced by *5% compared with using conduction oil to heat.

3.By Adopting our own cold trap technology, we can save cooling water and vacuum pipeline, thus to ensure the high efficiency and selectivity of the distillation process.

4.Our self-made oil diffusion pump with unique bundling nozzles has a very high compression ratio, and the backpressure can reach more than **0Pa, thus reduce greatly the demand for fore vacuum system. So the energy efficiency ratio is improved and at the same time the cost of production and maintenance is reduced.

5.We have developed automatic control of continuous rectification section of molecular distillation technology. Our equipment can separate natural matters, complex components and matters with a smaller molecular weight difference. Thus we can help our customers to improve their product quality and competitiveness.
