Problem 4 1500 kg of reactant A (MW = 200 kg/kmol) is added to 5500 kg of a mixture of organic solvent (MW = 300 kg/kmol) containing 60% excess of a second reactant B (MW = 125 kg/kmol) in a jacketed reaction vessel (R-301), the reactor is sealed, and the mixture is stirred and heated (using steam in the jacket) until the temperature has risen to 95 C. The density of the reacting mixture is 900 kg/m (time taken = 1.5 h). a) Find the size of reactor required. b) Find the time to heat the vessel contents from ambient to 95 C.
