Continuous Stirred Tank Reactors (CSTRs)

Plug Flow: In addition to excellent radial mixing, continuous reactors require plug flow conditions. Plug flow conditions means that all the material processed through the reactor must have the same residence time so that the chemicals exiting the reactor have witnessed the same reaction conditions of reactive species contact-time aging-temperature history. Completely Mixed Flow Reactor Complete mix flow regimes can be approximated quite closely in practice. In the case of CMF reactors, there is not an analytical solution to the advective dispersion equation Dd entrance Dd reactor Ddexit Reactor Figure 5-2 Schematic of a reactor with closed

Flow Reactors: There are two types of flow reactors in common use in the chemical industry. They are the continuous stirred tank reactor (CSTR) and the tubular reactors. CSTR or Mixed flow reactor(MFR) is configured much like a batch reactor except reactants and products continuously flow in and out of the reactor. The Coflore ACR is a 100 mL laboratory-scale flow reactor based on the principle of ten stirred tanks in series, employing a series of ten dynamically-mixed cells. The ACR delivers efficient mixing under excellent plug-flow conditions for reaction times ranging from seconds up to many hours.
