Nitrogen Recovery System Cuts Liquid Nitrogen Use by 50% at Changzhou Copper Tube Plant

A copper tube manufacturer in Changzhou has successfully operated our 400 Nm³/h, 99.9% purity nitrogen recovery system for one month. By recovering nitrogen tail gas from the heat treatment process, the plant has reduced its liquid nitrogen consumption by over 50%.

The customer originally relied heavily on purchased liquid nitrogen and was facing increasing costs and stricter energy-saving requirements. After evaluating their heat-treatment process, Kerong Gas delivered a compact, low-energy system that provides stable, high-purity nitrogen suitable for copper tube production.

After one month of continuous operation, the system has proven reliable, significantly lowering nitrogen costs while improving environmental performance. This project showcases an effective solution for energy reduction in copper processing and other heat-treatment industries.
