Sep 20, 2015· Dual Process Difference compared to Solvay''s process • In the dual process, NH3 is not recovered; hence no NH3 recovery tower (distillation equipment)t is required. • Also, lime kilns are not required if other sources of CO2 are available. • As the mother liquor is recycled, special attention must be paid to the water balance of the system.
Sodium carbonate (Na 2 CO 3) is found naturally or is manufactured from natural salt, sodium chloride (common salt).It has many uses but, one of the major notable applications is in making of glass. Soda ash is a key chemical for producing soap, paper making, baking soda production, and bleaching fabrics and paper.
A soda ash slurry system will allow the storage of approximately 250 dry tons of soda ash (30% solution) in a 158,000gallon tank (30'' high x 30'' in diameter). A tank of the same size would hold approximately 500 dry tons of 50% liquid caustic soda.

we try to make any process calculations it is good to have an understanding of the process flowsheet of a typical recausticizing plant as shown in Figure 1. From a control stand point recausticizing plant operation generally starts at the inlet of the green liquor clarifier or green liquor stabilization tank if one is installed. Operation
The Solvay process or ammoniasoda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammoniasoda process was developed into its modern form by Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from quarries).
Soda ash, or sodium carbonate (Na 2 CO 3), is a versatile alkali material, critical in the production of a litany of products and detergents and chemicals, to consumer products and water softeners, this material can be found in many of the products we interact with throughout our daily lives.
