AI Technical Summary

Technical Problem

The existing polyester final polymerization reactor has a problem of uneven heating during the heating process, which leads to equipment damage.

Method used

A combination of vacuum pump and isolation valve is used to control the temperature of gaseous heat transfer medium vapor by reducing the system pressure, avoiding excessively high temperatures in the initial stage. Subsequently, the absolute pressure of the vacuum pump is gradually increased to control the heating rate and ensure uniform heating.

Benefits of technology

This achieves uniformity in the heating process of the polyester final polymerization reactor, avoids equipment damage, and improves heating stability and safety.
