Reactors, also known as batch reactors or chemical reactors, are primarily utilized in chemical production processes to facilitate the reaction of two or more substances, resulting in the formation of a new compound. They find widespread application in the chemical, petrochemical, and pharmaceutical industries. Typically, reactors comprise a cylindrical vessel with dished ends, housing a top-mounted agitator equipped with one or more impellers driven by an electric drive and motor. Internal baffles and a jacket or internal coil are also incorporated, depending on the specific reaction requirements. These reactors can operate under pressure or vacuum conditions and at varying temperatures. Construction materials vary based on the corrosive nature of the process, commonly including stainless steel, mild steel with glass lining, and exotic alloys like hastelloy or incolloy. Reactors are available in a range of sizes, from laboratory-scale models to large industrial reactors, catering to the desired production volume of the user.
