Cstr performance equation
WebContinuously Stirred Tank Reactor (CSTR) Arranged as one long reactor or many short reactors in a tube bank ; no radial variation in reaction rate (concentration); concentration changes with length down the reactor 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 ...
