A solution of CH3COONa at a concentration of 0.3kg/kg solution is cooled from 348K to 290.7K in a Swenson-Walker crystallizer at a flow rate of 0.38kg/s. The concentration of the solution is 0.28kg/kg water at 290.7K. Cooling water is fed counter-current at a temperature of 280K and exits at 293K. Crystals of CH3COONa.3H2O are produced from the process and 2% of water is evaporated during cooling. Determine: i) yield of crystals, ii) amount of heat to be removed, neglecting heat to be removed for the vessel, and iii) length of the crystallizer, using a material with specific area of 2m2/m
