A Continuous Stirred Tank Reactor (CSTR) is an agitated vessel used in flow chemistry, that has a continuous feed of reactants and a continuous discharge of the reaction mixture (product). The feed and discharge rates are controlled to maintain constant reaction conditions (concentration, temperature and reaction rate) ensuring a consistent ...

The case of a single non-isothermal continuous stirred tank reactor [69, 90, 111] is studied in this chapter.The reactor is the one presented in various works by Perez et al. [98, 99] in which the exothermic reaction 𝒜→ℬ is assumed to take place.The heat of reaction is removed via the cooling jacket that surrounds the reactor.

A Continuous-Stirred Tank Reactor (CSTR) is a well-mixed vessel that operates at steady-state (Qin=Qout=Q). The main assumption in this case is that the concentration of the incoming fluid will become instantaneously equal to the outgoing upon entering the vessel. Fig. 2 explains visually this concept.
