Main performance and structure features:

The main components of the extract are CH;Cls, white oil and trace water. taking

advantage of the different boiling points of the three substances, the extract is carried

out in turn through a series of measures, such as initial distillation, atmospheric

distillation, vacuum gas extraction, CH:Cla and filtration of white oil. the extraction

solution was separated and purified to recover CH;Cl;(purity>99.97%)and white oil

(purity>99.97%)to meet the requirements of reuse in the production line and reduce

the material consumption of the produetion system, Reduce the production cost of the

separator film.
