✦ Synopsis

A system of one or more stirred tank reactors in series can be subjected to changes in working volume and throughput while maintaining a stationary residence time distribution. This in turn will ensure constant product quality-with arbitrary reaction kinetics-over a broad range of operating conditions. The results are directly applicable to demand changes and shutdown operations. They can be used to generate a controlled cycle in the discharge flow rate while maintaining constant product composition. If product quality depends on the exact form of the residence time distribution, there is no way to achieve uniform quality throughout a start-up. However, the total amount of substandard material can be held to an arbitrarily small limit.
