Part 4 RSmC Manufacturing sodium carbonate by the Solvay process
Manufacturing sodium carbonate by the Solvay process Sodium carbonate is used by many different industries as a raw material and about one million tonnes is produced each year in the UK all of it by the Brunner Mond Company in Northwich Cheshire. Also produced in smaller quantities is sodium hydrogencarbonate as well as calcium chloride as a by product a little of which can
water treatment the calciumcarbonate balance Degremont®
Carbonate calcium potential precipitation (CCPP) is an interesting parameter for quantifying what may be scaleforming or may have dissolving properties (pipes made from concrete) knowing that the CCPP is a level of concentration expressed in CaCO 3 (positive if water can cause scaling or negative if water is aggressive). Figure 99.
