Reactor diameter to height ratio
WebCalculate the volume from the reaction kinetics. Fix a diameter in order to fix the fluid velocity. Calculate the length of the reactor to match the volume previously calculated. If the fluid is liquid, the max velocity is around 2-3m/s, if it is gas, the velocity is higher, but I cant remember now.

The center of any chemical process is the reactor, where chemical reactions are carried out to transform feeds into products. Reactor design is a vital step in the overall design of a process. It is important to ensure that the equipment specified will be capable of achieving the desired yields and selectivity. See more The design of the reactor should not be carried out separately from the overall process design due to the significant impact on capital and operating costs on other parts of the process (Towler and Sinnott, 2013). See more Mixing plays an important role in many processing stages, including reactor performance. It is critical to select the appropriate method of mixing in order to ensure the process … See more Exothermic and endothermic reactions will require reactors with heat control systems to prevent operating conditions from falling out of the desired range.
