A CSTR is used in the production of vinyl chloride by reacting chlorine with ethylene C2H4 + Cl2 → C2H4Cl2. Both reactants enter the reactor at a molar flow rate of 10 mol/s. The feed stream is at a temperature of 75oC. The heat capacity for both reactants is 22 J/mol/k and for the product it is 44 J/mol/k, the heat of reaction (which is independent of temperature) is equal to -22,000 J/mol. Answer the following questions.  1. What will the steady-state temperature in the reactor be if you want to achieve a steady-state conversion of 80% in the presence of a heat exchanger with UA = 50 J/s/K, the coolant in the heat exchanger is at a temperature of 300K.2. You propose a new design where you want to completely remove theheat exchanger from the system. What is the new inlet feed temperatureif you want to keep the conversion at 80% and the temperature within the reactor the same as part a?

Question

A CSTR is used in the production of vinyl chloride by reacting chlorine with ethylene C2H4 + Cl2 → C2H4Cl2. Both reactants enter the reactor at a molar flow rate of 10 mol/s. The feed stream is at a temperature of 75oC. The heat capacity for both reactants is 22 J/mol/k and for the product it is 44 J/mol/k, the heat of reaction (which is independent of 
temperature) is equal to -22,000 J/mol. Answer the following questions. 

1. What will the steady-state temperature in the reactor be if you want to achieve a steady-state conversion of 80% in the presence of a heat exchanger with UA = 50 J/s/K, the coolant in the heat exchanger is at a 
temperature of 300K.
2. You propose a new design where you want to completely remove theheat exchanger from the system. What is the new inlet feed temperatureif you want to keep the conversion at 80% and the temperature within the reactor the same as part a?
