• Reaction stoichiometry: In batch production this is defined by the concentration of chemical reagents and their volumetric ratio. In flow this is defined by the concentration of reagents and the ratio of their flow rate. • Residence time: In batch production this is determined by how long a vessel is held at a given temperature. In flow the volumetric residence time is given by the ratio of the volume of the reactor and the overall flow rate, as most often, plug flow reactors are used. WebSep 21, 2024 · 2 Aug 2024, By Dr Samuel Adams. The mean residence time is the reactor volume divided by the volumetric flow rate. We can change the residence time by either changing the volume of the reactor or the flow rate. Molecules do not spend this exact time in the reactor.
