01
Jiangsu Shagang Group
Jiangsu Shagang Group, one of the largest private steel producers in China, required a reliable gas analysis solution to enhance the efficiency and safety of their converter gas recovery process. Their previous system suffered from delayed response times and unstable readings—posing challenges in process control and energy optimization.
Chang Ai Technology was selected to upgrade their system with in-situ laser gas analyzers capable of delivering real-time, interference-free data under harsh operating conditions.
02
Zhejiang Haichang Gas
Zhejiang Haichang Gas Co., Ltd., a key supplier in the industrial gas sector, required a high-precision solution to ensure the purity of cryogenic gases—specifically Argon and Nitrogen—stored in their bulk tanks. Given the critical nature of trace impurities in ultra-high-purity gas distribution, Haichang Gas sought to implement a robust, automated monitoring system capable of sub-ppm level detection.
