(d) The quantity of crystals formed In the recovery of glycerine from spent soap lye, 10000 kg/h of lye containing 10.5% glycerine and 11.5% salt (NaCl) is concentrated by evaporation. The concentrated solution leaving the evaporator contained 80% glycerine and 5% salt. Entrainment loss is estimated to be 2% of the glycerine in the charge. Calculate the quantity of (a) The water evaporated per hour (b) The salt crystallised per hour
