摘要：
Results of realization of energy saving technologies in the processes of continuous deaeration and two-stage vacuum crystallization of sodium sulfate from solutions in viscous production were indicated. Changing the steam inject method of vacuum evaporation and removing secondary vapour on condensation allowed decrease of total power input more than 3 times, water vapour and cooling water - in 6-10 times. The output of dehydration of Glauber's salt to anhydrous crystal sodium sulfate increased in half. Ecological purity of the technologies was achieved by decrease of industrial sewages and disposal of waste waters.
