Technology Transfer for Complete Sets of Soda Ash Production via the Combined Soda ProcessThe combined soda ash process co-produces soda ash and ammonium chloride, featuring high utilization rates of raw salt and zero solid waste discharge, making it one of the mainstream soda manufacturing processes in China. Decades of engineering practice have been accumulated in this technical direction, completing the design of multiple combined soda projects with capacities ranging from 450,000 to 1.2 million tons per year, covering various types such as new construction, expansion, and relocation renovation. Related projects have repeatedly won national and provincial-level awards for excellent engineering design.
Core technical highlights include optimization of the carbonation system, improvement of mother liquor circulation efficiency, and enhancement of ammonium chloride drying and granulation processes. The transfer content covers the complete process technology package, basic design, operating procedures, and personnel training, suitable for enterprises with synthetic ammonia facilities or conditions for purchasing liquid ammonia.
