Subject of the current case:
application of the mixing tank for a batch organic synthesis process that includes two parallel homogeneous reactions.
The main product is obtained as a result of a second order reaction between reactant A and B as A + B > C, the specific reaction rate is estimated as 0.12 l/(mol.s). Along with the main product, some quantity of a by-product is formed as a result of the parallel reaction: B+B>D with specific reaction rate 0.006 l/(mol.s).
Before start of the process the reactor is filled with solution of reactant A (concentration is 0.8 g-mol/l).
The equimolecular quantity (B/A = 1) of the reactant B is added instantly on the surface of liquid, on some distance – about 300 mm – from the tank wall. Sensor is placed at bottom of the tank.
Tank Elliptical bottom:
Baffle (Flat, at a distance to the tank wall):
