Abstract. The pH control problem in a continuous stirred tank reactor is studied from both atheoretical and application point of view. A reaction invariant model for an acid-base system, which is one of the most complete descriptions for the pH control problem, is utilized. The new controller obtained for the pH control problem is based on a ...

A continuous stirred tank reactor (CSTR) is a container used for chemical reactions. It allows the substances needed for the reaction to flow in, while the products flow out at the same time. This makes it a great tool for making chemicals continuously. The CSTR reactor mixes the substances well and works consistently under steady conditions.
