Where are reaction kettles used in chemical production?

Where are reaction vessels used in chemical production? Kettle type equipment (or tanks) with agitators is one of the widely used reactors in the chemical industry. This reactor can be used for liquid-liquid homogeneous or heterogeneous reactions. For example, liquid solid and gas-liquid solid are equal; It is widely used in petrochemical industry, essence and spice, medicine, pesticide and other industries. Used to complete processes such as polymerization, hydrogenation, and nitrification, as well as other processes such as organic dyes and pharmaceutical intermediates.

The most common polymerization reaction is 90% carried out in a stirred tank reactor, such as PVC. Most domestic PVC manufacturers use polymerization reactors made of stainless steel or composite steel plates, as well as partial polymerization processes using enamel reactors. For example, the production of polyester resin uses bulk melt polycondensation, and polymerization also uses a kettle reactor. In the production of Fine chemical such as dyes, medicines and spices, almost all Almost all can be carried out in reactors.

　　Kettle reactors are widely used in industry due to their simple structure, convenient processing, high mass transfer efficiency, uniform temperature distribution, and wide controllable range of operating conditions (such as temperature, concentration, residence time, etc.) Flexible operation and convenient replacement. Secondly, with the development of the human chemical industry to this day, the process design of kettle type devices has become more mature, and talent reserves and training are also quite sufficient. Therefore, the application of kettle type devices is the first choice for many process engineers.
