Biodiesel molecular distillation technology is a high vacuum (0.133 1 pa) under the condition of using the different nature of the average degree of freedom for the different molecular overflow surface to achieve separation of matter. The biodiesel technology available can be operated below the boiling point temperature, long heating time and high separation degree of the material, especially suitable for high boiling point, high heat sensitive and easy oxide separation, extraction and purification, can solve a lot of with conventional separation technology is difficult to solve the problem.
Adopt molecular distillation technology processing biodiesel, do not need washing and drying process, the technological process is simple, does not produce waste water, save water treatment cost, but the molecular distillation requires high vacuum degree, so this
biodiesel technology have high energy consumption and equipment investment.
