Continuous stirred-tank reactor
A continuous stirred-tank reactor (CSTR) develops a reaction vessel in which the filled reactants are continuously added as the products are continuously removed. The vessel is stirred continuously to maintain a homogeneous concentration of the reactants in it, and the exiting stream has the equivalent composition. Such a system is considered to be an open system. The reactants are freely introduced into the system while products are continuously removed. The vessel, also related to the tank or the reactor with its contents, collectively called the system. The system is kept in steady conditions with time. This state of constant conditions is referred to as the steady-state. Regularly, a continuous stirred-tank reactor can be represented, as shown in the figure below.
