Scale-up of batch reactor with BatchReactor
The BatchReactor software has demonstrated its usefulness for optimizing the operating conditions of discontinuous chemical reactors, for conducting safety studies on such reactors, while controlling temperature and pressure, and also for scale-up between laboratory equipment, pilot plant and the industrial unit.
In order to further facilitate these scale-up phases, new functionalities have been added and, in particular, the possibility of performing an extrapolation calculation for a mechanically stirred tank:
- Values of the characteristic variables (rotation speed, power …) as a function of the invariant retained (power density …).
- New geometry taking into account the extrapolation factor (geometric similarity).
- Extrapolation of gas supplies (surface velocity or constant vvm).
- Calculation of vortex depth (in the absence of baffles).
It is also now possible to define several identical agitators on the same shaft for a given number of the available mixing devices. The high-efficiency thin blade Chemineer HE3 propeller has also been added as well as the turbine with curved-blades at the turbine bottom (Pfaudler type).
These improvements were implemented in BatchReactor, and also in BatchColumn software (simulation of batch distillation columns) where the boiler can be a stirred tank
