Activity 2: Which reactor is best for batch-to-continuous processing? The same Client has undertaken kinetic studies corresponding to the hydrolysis of aqueous acetic anhydride (to yield acetic acid) at 40C. They have found that this is a first-order, irreversible reaction, with a rate constant of 0.38min1. The Client is interested in scaling-up their acetic anhydride process, and have proposed the following two alternatives (written in red). Notes from Client - A CSTR thermostatted at 40C, of 1.8L volume, with an input stream of aqueous acetic anhydride at a concentration of 0.187M. - This has actually been tested in our labs - for an entry volume flow rate of 0.5Lmin1, we observed that 58.3% of the acetic anhydride was converted. - A plug-flow reactor thermostatted at 40C, of the same volume as the CSTR, with the same volume flow rate. Notes from Team Leader - How do the Client's experimental results with the CSTR compare with their batch reactor findings? - In terms of productivity, which of the two options do you recommend? - If the two alternatives were to have the same conversion, how would the flow rates differ? Does this change your recommendation
