Production neutralizating salt solution and salt isolation by means of polytethermic crystallization is studing. That settles utilization waste materials end lowerling energy expenditure work out. When for absorption make use 21% natrium carbon solution it is necessary evaporate 4,6 ton water on one ton good salt. On composition diagram it is illustrated necessity production salt in condition with little water crystal without evaporation salt solution. Circulating technology salts of render harmless gas is offer. This technology in clude stage: absorption component from harmless gas; neutralization absorptive solution; crystallization salts; educe of suspended particles salts. Circulating number 1-1,2. Experimental results productious sodium sulfite and ummonium chloride show highly effetiveness offer principle economy of energy. It is illustrated cutting of production energy loss was decreased in 3-5. Сirculating number total mother liquor or on acid solution neutralization makes up 1-1,2 . Productivity in neutralization stage increase 1,6-1,8 time. Productivity techologycal sistem increase in 1,25.
