Design a continuous stirred tank reactor (CSTR) for the exothermic reaction A + 2B -> C with the following conditions: - The reactor should produce a minimum of 5 moles of product C per hour- The feed ratio of A to B should be 1:2- The temperature of the reactor should not exceed 50°C- The volumetric flow rate of reactant feed is 10 L/hour- The reactor should have a residence time of at least 4 hours. Assuming all reactants are available in excess, determine:- The required volume of the CSTR- The heat generated by the reaction- The cooling rate required to maintain the reactor temperature below 50°C

Question

Design a continuous stirred tank reactor (CSTR) for the exothermic reaction A + 2B -> C with the following conditions: -

Answer 1

1. Required volume of the CSTR:The residence time    is given as 4 hours. The volumetric flow rate  Q  is given as 10 L/hour. The volume  V  of the CSTR can be calculated using the formula:V =  * QV = 4 hours * 10 L/hour = 40 LSo, the required volume of the CSTR is 40 liters.2. Heat generated by the reaction:To calculate the heat generated by the reaction, we need to know the heat of reaction  H  for the given reaction A + 2B -> C. Since this information is not provided, we cannot calculate the exact heat generated by the reaction. However, we can represent it as:Heat generated = moles of product C per hour * HHeat generated = 5 moles/hour * H3. Cooling rate required to maintain the reactor temperature below 50C:Again, without knowing the heat of reaction  H , we cannot calculate the exact cooling rate required. However, we can represent it in terms of H as:Cooling rate = Heat generatedCooling rate = 5 moles/hour * HIn summary, the required volume of the CSTR is 40 liters, and the heat generated by the reaction and the cooling rate required to maintain the reactor temperature below 50C are both dependent on the heat of reaction  H  for the given reaction A + 2B -> C.
