STUDY OF THE DESULFURIZATION PROCESS OF BRINE FROM THE KARAUMBET AND BARSAKELMES LAKES

The research results on the desulfurization of brine from the Karaumbet and Barsakelmes lakes using distiller liquid, a by-product of soda production, are presented. It is shown that the optimal technological parameters are a distiller liquid dosage of 100-105%, a temperature of 20-30°C and a process duration of 20-30 minutes, under which the degree of desulfurization reaches 95%. Deep purification with sodium carbonate reduces the calcium chloride content by 0.66% and introducing barium chloride in 100% relative to the residual sulfate content reduces the sulfate concentration to 0.001%.
