Abstract:
     Combine production method of salt and pure soda belongs to a comprehensive utilization of brine, sea water and waste soda solution. Production of an ammonia-soda plant is combined with the production of a saltworks. The same saltworks is used both for production and for sale. Crude salt is melted into water and the solution is supplied directly to the soda plant. In this case, the steady supply can be insured, and the cost of soda production will be reduced owing to economy of transportation and process. Waste solution from the soda plant can be transfered to saltworks for evaporating brine in the sun to make salt. This makes output of salt increased and quality of product improved. Plaster magnesium chloride, bromine, calcium chloride, potassium chloride will be the by-products. The qualities of all of these by-products are improved because of the adding of waste solution. The cost of production is decreased relevantly. It is very benificial to use this technology in both ammonia soda
