Highlights：
1.LifenGas rapidly mobilized during the Spring Festival to deliver critical on-site technical support for an overseas ASU project in Texas.
2.The joint team successfully resolved complex system issues and achieved the first successful commissioning of the ASU.
3.The project highlights LifenGas’s global service capabilities and its strong partnership with the client.
On the eve of the 2026 Chinese Lunar New Year, LifenGas received an urgent request for technical support from Texas, USA. A 10,000 Nm³/h oxygen-nitrogen air separation unit (ASU), for which LifenGas supplied the cold box, encountered critical technical challenges during operation, requiring immediate on-site assistance.
In rapid response, LifenGas promptly activated its emergency support mechanism and assembled a multidisciplinary team of experts specializing in electrical, instrumentation, and control systems. Despite the Spring Festival holiday, the team mobilized without hesitation and traveled to the United States. Although flights were delayed due to a severe Texas blizzard and other travel challenges, the team arrived on site and quickly collaborated with the client’s local experts to initiate troubleshooting efforts.
Upon arrival, the team found the situation to be more complex than expected. Through close collaboration, the joint team systematically identified and resolved multiple underlying issues, including signal distortions in key instruments, sensor irregularities, probe channel failures, and abnormal readings from the cooling tower level gauge caused by extreme weather conditions. The most critical challenge—a system-wide startup failure of the liquid pumps—was successfully resolved through detailed analysis and coordinated effort. All rectification work was completed efficiently, culminating in a successful first-time commissioning. In addition, the ASU’s control logic and operational strategies were comprehensively optimized, ensuring stable integration and reliable performance of the entire electromechanical system.
Following the successful startup, the teams transitioned into the operational support phase. Engineers continuously monitored DCS data, optimized molecular sieve cooling and heating cycles in line with local climate conditions, recalibrated alarm parameters, and enhanced the DCS interface for improved usability. Comprehensive on-site training was also provided to local operators, covering system operation, early fault detection, and emergency response procedures.
The ASU has since been operating steadily, delivering a continuous supply of high-purity oxygen and nitrogen, and serving as a critical support for a major glass manufacturing production line in the United States. The project has received strong recognition and positive feedback from the end customer.
This mission in Texas not only demonstrates LifenGas’s strong technical expertise and global service capabilities, but also highlights the effective collaboration and complementary strengths between LifenGas and the client. Looking ahead, LifenGas remains committed to partnering with customers worldwide, leveraging advanced technologies and professional services to ensure safe, stable, and efficient industrial operations.
