AI Technical Summary

Technical Problem

The existing combination of alcohol-ammonia process and melamine unit in production is unstable in terms of high-pressure nitrogen supply, which leads to instability in the safety and operation of the gasification unit and fails to meet production needs.

Method used

Design a high-pressure nitrogen device that combines an alcohol-ammonia process with a melamine plant, including a liquid nitrogen storage tank, a liquid nitrogen storage vessel, a water bath vaporizer, and a vaporization emergency nitrogen compressor. Through optimized connection of liquid nitrogen pipelines and pumps, combined with the use of valves and instruments, a stable high-pressure nitrogen supply can be achieved.

Benefits of technology

It provides a safe and stable supply of high-pressure nitrogen, ensuring the safe and stable operation of the alcohol-ammonia process and melamine unit, and improving the operating cycle and pressure stability of the equipment.
