Abstract

The optimal technological parameters for the production of caustic soda from sodium carbonate and sulfate and calcium hydroxide have been established. The influence of the concentration of lime milk on the rate of filtration by sediment and filtrate has been studied. Purpose of the Work: The purpose of this work is to determine the physicochemical basis for the production of sodium hydroxide and burkeite by causticization of sodium carbonate and sulfate. Scientific Novelty: In comparison with the known works, a theoretical profoanalytical analysis of the one-cation of four-component system and its constituents was carried out for the first time, and also determined the optimal technological parameters of causticization of solutions for local carbonates and sodium sulfates. Features of the Work: - the influence of the main technological parameters on the processes of causticization, filtration, evaporation; - research of intermediate and finished products by modern physicochemical methods; - study of the rheological properties of the solution depending on the temperature and concentration of the resulting solutions.
