A reactor is a device used for chemical reactions, which allows raw materials to react under specific temperatures and pressures to produce the desired products. Typically, a reactor consists of a cylindrical vessel with an internal agitator, equipped with feed and discharge ports as well as various control valves. The agitator's purpose is to thoroughly mix the raw materials and facilitate the reaction process. The operation of a reactor can be manual or automated, controlling and optimizing the reaction process through parameters such as temperature, pressure, and agitation speed. Reactors are widely used in industries such as chemicals, food, and environmental protection for various chemical reactions, including polymerization, condensation, addition, cracking, and hydrolysis, among others. The design of a reactor must consider the reaction process requirements, material properties, temperature, pressure, and factors such as the type and power of the agitator to ensure smooth operation and reliability.
