An exothermic reaction is carried out by controlled addition of reactant B in to a batch reactor system contained reactant A with solvent medium.
Reaction heat removal is taking in place by boil up the solvent (reaction temperature here is BP of the solvent)
Reaction temperature is being controlled by 1) limiting reagent B addition rate to the reactor 2) self reflux solvent sent back to the reactor.
Solvent is Hexane and the reaction temperature is 64-67 deg C.
Exotherm evolves per hour is 77000 Kcal/hr. calculated based on calorimetry study and Hexane Boil up rate is 960 Kg/ hr. Boiled Hexane condensed and cooled to 25 deg C and send back to the reactor.
Questions: 960 Kg/Hr of Hexane at 25 deg C, sent back to reactor. so how it will effect on slow down the reaction rate and what is the resultant temp of the reactor? (total mass A=100 Kg, B = 500 kg addition at 2 Kg/min. total solvent in the reactor is 1500 Kg?).
To maintain the reaction temp at 65 deg C and continue the same reaction rate, how much increase addtion rate from current rate 2 Kg/hr?
