2. The process given in the figure is used to increase the concentration of CaCl, solution. Fresh feed contains 5% CaCl, (wt/wt), after mixing with the recycle stream, the CaCl ratio increases to 10% (wt/wt). After the process, there is 0.1% Cacl, in the stream D. Concentrated solution with a flow rate 100 kg/h contains 15% CaCl, by mass taken from the system. According to this; a) Label the flowchart of the process and do the degree-of-freedom analysis. b) Find the rate of fresh feed. c) Determine inlet and outlet mass flow rates of unit process (W,M) d) The fraction of the CaCl; leaving the unit process that recycled. e) Find the ratio of mass flow rate of recycle stream to fresh feed. Recycle, R 10.0 % CalCl Fresh Feed, F Linit process 5.0 % CalCl; 15 % CalCla 100 kg/h Stream, D 0.1% CalClz
