METHOD FOR CONCENTRATION OF SOLUTIONS WHICH CONTAIN SODIUM SULFATE Russian patent published in 1996 - IPC

Abstract RU 2060939 C1

FIELD: production of viscose. SUBSTANCE: secondary steam of vacuum evaporation device is neutralized to pH being approximately 7 and then it is compressed to pressure of heating steam. Then wetting to saturation is carried out. Thus treated solution may be used during evaporation process. EFFECT: decreases expense of heat energy of vapor, decreases total energy expenses. 1 dwg, 1 tbl
