Variation of Temperature and Concentration versus Residence Time in Adiabatic Reactors
A first-order chemical reaction taking place either in an adiabatic CSTR (continuous stirred tank reactor) or an adiabatic PFTR (plug-flow tubular reactor). This simulation plots concentration CA and temperature T versus the residence time for both types of reactors. Sliders are used to set the initial concentration, CA0, and the value of parameter J = -ΔHRCAo/rcp, where ΔHR is the heat of reaction, r is the fluid density, and cp is the fluid heat capacity. For a range of the residence time values, up to three solutions can exist for the CSTR. A stability analysis can show that only two of the solutions are stable.
