Crafting excellence with匠心, overcoming countless challenges through实干 — A record of the completion of the Host Yanting Natural Gas Processing Plant project

The PetroChina Southwest Oil and Gas Field Yanting Natural Gas Processing Plant project is a strategic-level engineering initiative for 2025, spearheaded by Host Oil and Gas Technology Co., Ltd. It plays a critical role in ensuring the stable supply of natural gas to the Sichuan-Chongqing region by providing core equipment for vital commissioning tasks. From February 24 to May 18—spanning 83 grueling days—the team tackled eight major operational modules under some of the most extreme environmental and operational conditions: freezing cold temperatures (with the lowest site temperature dipping as low as 0°C in February), scorching heat (peaking at 35°C from late April through the project’s conclusion), and high-pressure challenges (including XAI helium gas area leak-testing pressures reaching up to 25 MPa). Key tasks included successfully commissioning the thermal oil circulation system, drying eight specialized gas-handling units, and pre-cooling and filling storage tanks of various sizes—all while maintaining precision and efficiency under these demanding circumstances.
