AI Technical Summary

Technical Problem

In the existing α-pyrrolidone production process, the transfer of materials between different facilities consumes a lot of energy, and the heat of the high-temperature reaction materials is wasted. The electronic temperature control valve is expensive to set up, which increases the production cost.

Method used

An integrated system consisting of a static mixer, a synthesis reactor, a combined processing unit, and a product tower is adopted. The gasification temperature is controlled by the physical changes of the temperature-sensing liquid using a temperature-controlled gas valve, which avoids material transfer and heat waste. Heat transfer oil is used to absorb the heat of gasification and supply it to the external ammonia removal tower.

Benefits of technology

It enables seamless material handling, saves production costs and energy consumption, reduces heat waste, and lowers the energy demand of the production line.
