Abstract

Sodium carbonate crystallization is studied on an industrial test scale with supply of condensed soda pulp into the production vessel of an evaporator battery, and the effect of soda pulp supply conditions on an increase in the period between washings is determined. The size of soda crystals is compared with different Na2CO3 solid phase concentration in evaporated pulp, and evaporation battery operating parameters are determined. Further areas for changing the equipment and production scheme for alumina manufacture with the use of a soda seed in all evaporator batteries are determined.
