On June 10, with the final section of the steel inner cylinder precisely installed, the chimney steel inner cylinder for Xinjiang Tianchi Energy Co., Ltd. 's Zhundong 2 billion cubic meters/year coal-to-natural gas project was successfully topped out, marking the successful completion of the core construction task for the project's chimney and laying a solid foundation for subsequent boiler ignition and timely commissioning of the project.

This project is a key coal chemical engineering initiative of the autonomous region and a critical gas supply project for the national West-East Gas Pipeline, with a total investment exceeding 17 billion yuan. It is located in the Zhundong National Coal, Coal Power, and Coal Chemical Industry Base. Upon completion, it will produce 2 billion cubic meters of clean natural gas annually, promoting the clean and efficient utilization of Xinjiang's coal resources and contributing to national energy security as well as the implementation of the "dual carbon" strategy. The chimney, serving as the core environmental protection structure for emissions, involves high-altitude and high-risk construction work for its steel inner cylinder. Situated in a desert environment characterized by persistent winds and significant day-night temperature fluctuations, coupled with stringent welding precision requirements and complex coordination challenges, the project poses substantial difficulties for on-site construction organization.

Since the commencement of construction on the steel inner cylinder, under the comprehensive planning and precise coordination of company leadership at all levels, the project team scientifically optimized the construction plan, adopted a mature and reliable hydraulic lifting technique, strictly implemented safety measures for high-altitude work and full-process quality control for special welding operations, conducted non-destructive testing on every weld seam, and rigorously adhered to the three critical requirements of safety, quality, and schedule. All participating personnel overcame the harsh conditions of the Gobi Desert through round-the-clock efforts and close collaboration, efficiently coordinated personnel, equipment, and material supplies, actively coordinated with supervisory agencies, construction teams, equipment suppliers, and other stakeholders to work in concert, successfully addressed numerous challenges including construction under high-temperature and strong wind conditions as well as precise alignment of the cylinder body, and achieved this major milestone—the successful elevation of the steel inner cylinder to its final position—with high standards.

The successful completion of this milestone would not have been possible without the strong support and close collaboration of the company's leadership and all departments. From the initial plan review and on-site resource allocation to process safety supervision and coordinated support measures, every step involved demonstrated collective dedication and hard work.

Next, the project team will leverage the successful completion of the steel inner cylinder as an opportunity to maintain strict safety and quality standards, steadily advance subsequent tasks such as chimney anti-corrosion and insulation work as well as installation of auxiliary facilities, and fully accelerate subsequent construction activities. By demonstrating concrete commitment, we aim to seize the critical construction period and ensure the project is completed and commissioned on schedule, thereby contributing to the green transformation of the regional energy structure and high-quality development of the local economy.
