about the stripping machine in solvent extraction

Dense miscella from the solvent extractor pump will be stored in temporary storage and clarify further, the miscella tank accumulated at the bottom part of the slag regularly by the return sludge pump hit back extractor; clarification of the oil by steam feed pump into the first evaporator. From DTDC stripping machine at the top of the solvent and the water vapor mixed gas (steam) by wet collector by hot water collector set meal last into the first evaporator shell as the heating medium. The solvent vapor is discharged from the top of the first evaporator vapor liquid separation chamber into the main condenser. Main condenser (and 1^st steaming, 2^nd steaming, vacuum stripping with the same) vacuum by steam jet pump, steam jet pump is equipped with the automatic control device, which can automatically to keep the vacuum system stable. Concentrated miscella from the first evaporator separation chamber and flows out of the bottom, by the second steam feed pump into mixed oil for heat exchanger with the stripper extraction pump hit the hot crude oil heat exchange, by heating the miscella into the second evaporator, the second evaporator with indirect steam heating and provided with a temperature automatic control device. Second vapor concentration miscella from the second evaporator separation at the bottom of the chamber through the upper sealing liquid flowing into the dish type stripper, disc type stripper bottom pass directly into steam, remove residual solvents, mixed vapour into the main condenser. Remove residual solvent by disc type stripper spare pump. Disc type stripper is arranged at the bottom of the liquid level automatic control device, which ensure that the liquid seal and the stability of the refined oil flow, extraction of crude oil by mixed oil for heat exchanger heat, crude oil cooled into the extraction crude oil tank.
