Caprolactam polymerization training equipment

Caprolactam polymerization training equipmentIt is a reaction in which one or several small molecule compounds become large molecule compounds (also known as polymer compounds or polymers, usually with a molecular weight of 1 × 104-1 × 107), and the process involving polymerization reaction is called polymerization process. There are many kinds of polymerization processes, which can be divided into bulk polymerization, suspension polymerization, lotion polymerization, solution polymerization, etc.

The process hazards are as follows:

1. Aggregated raw materials have self aggregation and explosion hazards;

If the heat cannot be removed in a timely manner during the reaction process, cracking and polymerization will occur as the material temperature rises, and the generated heat will further intensify the cracking and polymerization process, leading to a reactor explosion;

3. Some polymerization additives are highly hazardous.

control scheme

The pre polymerization reaction of caprolactam polymerization process is an endothermic reaction, while the post polymerization reaction is an exothermic reaction. It is necessary to focus on monitoring the pre polymerization reactor, post polymerization reactor, and feed flow rate. The monitored process parameters include reactor temperature, pressure, and raw materialsABC tank feed flow rate.

Key monitoring process parameters:raw materialABC tank feed flow rate; Pre polymerization reactor temperature and pressure; Temperature and pressure of the post polymerization reactor.

Basic requirements for safety control:Reactor temperature and pressure alarm interlock; Emergency shut-off valve for accidents; Local exhaust facilities.

Control method:Once an abnormal phenomenon or leakage accident occurs in the system, an emergency stop should be initiated through the automatic interlocking device.
