The objective of this section is to determine how multiple steady-states might arise. Also, we show how to generate steady-state input-output curves that show, for example, how the ... WebCSTR Model. The adiabatic continuous stirred tank reactor (CSTR) is a common chemical system in the process industry, and it is described extensively in [1]. A single first-order exothermic and irreversible reaction, A → B, takes place in the vessel, which is assumed to be always perfectly mixed. The inlet stream of reagent A enters the tank ...

"WebA unique feature of a biological CSTR is the washout point. When the flow rate is increased so that the microbes can no longer reproduce fast enough to maintain a population, the microbes wash out of the tank, and the reaction ceases. This washout point represents the limits of maximum flow rate for operation. IV.D.2 Classification " - Cstr washout curve
