In the process sketched in Figure, Na2CO3 is produced by the reaction Na2S + CaCO3 → Na2CO3 + CaS. The reaction is 90% complete on one pass through the reactor, and the amount of CaCO3 entering the reactor is 50% in excess of that needed. Calculate on the basis of 1000 lb/hr of fresh feed (a) the pounds of Na2S recycled, and (b) the pounds of Na2CO3 solution formed per hour. 1000 lb/hr 45% Na S 55% H₂O 30% CaCO₂ 70% H₂O 1923 lb hr Fresh Feed 30% CaCO, soln Pure Na $ REACTOR 60 lb/hr CaCO, CaCO, Soln H₂O 20% CaS soln $0% NaCO₂ 20% H₂O In the process sketched in Figure, Na2CO3 is produced by the reaction Na2S + CaCO3 → Na2CO3 + CaS.
