A continuous stirred tank reactor (CSTR) is preferred for kinetic studies, especially when a complex kinetic model needs to be developed. Stirred tank reactors operating in batch and semi-batch mode are found to be the most commonly used to perform slurry-phase experiments. This chapter deals with the experimentation in CSTR …

Summary. Stirred tank reactors are widely used in the chemical and allied industries. They offer excellent flexibility in meeting varying demands of a reaction. The most common version of the tank or vessel is a vertical cylindrical tank with a dish end at the bottom. Impellers commonly used in stirred tank reactors are divided into radial …

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.
