Simulation of the new combined process of Ca-method and Na-method to produce high purity calcium hypochlorite

In the chlor-alkali industries, the major products, including, chlorine and hydrogen gases, and also sodium hydroxide are produced by electrolysis of the saturated brine.One of the most important minor products in these industries is the calcium hypochlorite. The production process has a lot of problems such as environmental issues including the high wastewater volume which is the most significant one. This causes that the production reduces in our country despite the key role of this product in the water and wastewater industries.Based on the patented plan in Chloran Chemical Production Company, these problems are resolved by a new process method in which the calcium hypochlorite is produced by combination of the Ca-method and Na-method processes and whole the wastewater is used as the precipitating agent in the secondary purification of the saturated brine and as the raw material in the calcium chloride production unit. In this article, we are trying to approve the possibility of this new process by Aspen plus simulating software.[1,2]
