Diluted streams A and B are continuously fed into a CSTR(Continous Stirred Tank Reactor) where they react rapidly, releasing 280kCal of heat per kg of solution A. The reaction is 100% complete and therefore the heat released is independent of the reaction temperature. Inside the cooling coil placed in the reactor, cooling water circulates at a high flow rate and therefore the temperature rise in the cooling water is negligible. (a) Draw the physical diagram and calculate the temperature of the output current under steady state conditions. (b) The cooling water temperature suddenly drops to 15C. What is the temperature of the output current after 5 minutes due to the effect of this drop? Given: Feed flow rate of solution A to the reactor MA=500kg/h Feed flow rate of solution B to reactor MB=500kg/h The CP heat capacity of the solution streams and the output current is the same and is 1.0kCal/(kgK) The constant amount of liquid in the reactor (liquid filling, hold-up) is 2500kg. The temperature of both input currents is 25C Cooling water inlet-outlet temperature 20C The heat conduction area of the cooling coil is 3m2 and the overall heat conduction coefficient is 2900kCal/(hm2K)
