How should a hydrolysis reactor with a reaction time of four hours be considered?
Thread Content
The catalyst chosen was a heterogeneous catalyst; the catalyst literature provides a kinetic equation and a reaction time of 4 hours, for an ester hydrolysis reaction. The previous consideration was to use multiple consecutive stirred tanks in series, but how should the number of series connections be determined? Another idea is the batch reaction, with several reactors taking turns discharging their products.
Why use multiple mixing tanks in series? Do you need to react like this multiple times?
No need for multiple reactions; can one reactor achieve it? Is the reaction time four hours or is it continuous operation?
Do not connect in series; parallel connection should be better. Calculate the feeding time and discharging time properly
Well, based on the processing volume and residence time, with a loading rate of 0.5–0.6, we need to calculate the required volume. If the diameter is too large, it will definitely affect the mixing effect; by observing the changes in the reaction rate, we can determine the residence time for each of the four reactors
It is not recommended to use batch reactors for continuous production, as the design of batch reactors inherently leads to insufficient mixing and residence time of the reactants in such processes. This is especially true when feeding material at the final stage of production; as a result, either the yield is low or the reaction is incomplete. Therefore, my personal suggestion is that, since a batch reactor is chosen, it should be used in parallel and calculations should be based on batch reactions, to ensure that the material in each reactor is completely converted.
