Negative pressure evaporation process

The liquid from the extractor is the miscella containing grease and oil, which can be separated out according their different vaporization temperatures. Our company mainly uses vacuum evaporation technology, and it can reduce solvent leakage and consumption. The separated solvent vapour is cooled and recycled back to the extractor for reuse, which can improve the solvent efficiency. 

Solvent condensation & recovery process

Solvent condensation system combines with evaporation system closely, and evaporative condenser and steam stripping condenser all work under negative pressure. Non-condensable gas enters the energy saver from the shell of the first evaporator. In energy saver, non-condensable gas exchanges heat with condensate from the evaporative condenser. Finally, the condensate temperature discharged from energy saver is increased, and the solvent separated from water goes to solvent holding tank. 

Paraffin oil recovery process

Tail gas first enters paraffin absorption tower, and then comes the counter-current absorption of paraffin and tail gas, which can reach the ideal state when the stainless steel packing has large surface area. The solvent content in discharged liquid paraffin (called rich oil) is not more than 5%, so as to ensure the maximum absorption rate.
The paraffin rich oil is pumped into the heat exchanger to exchange heat with paraffin lean oil, and then goes to paraffin heater, and finally enters paraffin analysis tower. 

Extraction Advantages

1) The material is divided into several independent units on the material bed, which can effectively prevent miscella at all levels from fleeing hither and thither on the material layer and ensure the concentration gradient between several sprays.
2) Immersion area appears in each lattice, which can help achieve better immersion effect.
3) The chain box is supported by track and can prolong the service life of screen deck by not touching it.
4) The towline extractor is driven by world leading double-shaft hydraulic motor, with balance force, reliable operation and less maintenance cost.
5) Specialty suitable for the extraction of high oil and high power materials, and better immersion effect can be expected for ordinary oil plants.
