THERMAL SEPARATION OF MIXES OF MATERIALS BY PRIMARY EVAPORATION AND DEGASSING PERFORMED IN SEPARATE MIXERS Russian patent published in 2014 - IPC B01D1/22 B01D19/00 C08F6/10 

FIELD: process engineering.

SUBSTANCE: invention relates to continuous thermal separation of mixes of materials, particularly, solutions, suspensions and emulsions. Proposed process is divided into main evaporation and degassing to be performed in separate mixers. Main separation is performed in evaporator-mixer while degassing is performed in degassing mixer. Note here that both mixers comprise continuous-operation working and gas chambers. Proposed method consists in that polymer solution thickened in evaporator-mixer is continuously discharged via outlet and fed into degassing mixer. At degassing in degassing mixer, polymer solution temperature is maintained below that which can cause destruction of polymer solution. Note also that temperature is adjusted by addition of volatile or gaseous additives not dissolving in polymer solution at one or several points of degassing mixer.

EFFECT: higher efficiency of degassing.
