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. Fig. 2. Continuous-Stirred Tank Reactor

In continuous reactors, reactants continuously pass the reactor where the chemical reaction takes place and the end product is received at other point. Continuous reactors are installed in industries where large quantities of chemical is being produced. The two main types of continuous reactors are:- Continuous Stirred- Tank Reactor (CSTR)

Continuous stirred-tank reactors (CSTRs) are frequently used plants in the chemical and food industries. Control of CSTRs is a challenging problem due to the non-linear behaviour, multiple steady-states, heat effect of the chemical reactions, time delay, and effect of various time-varying uncertainties, see ( Luyben, 2007, chap. 1 ).

Batch reactors contain ports for injecting reactants and removing products, and can be outfitted with a heat exchanger or a stirring system. While batch reactors are generally of constant volume, some are designed to maintain a constant pressure by varying the reactor volume. The picture below shows the top of a batch reactor.
