Introduction
Deep in the heart of the Sichuan Basin, a decisive battle over national energy security is quietly intensifying — the Southwest Oil & Gas Field’s “50 bcm production target” has entered its final sprint. Ziyang Natural Gas Purification Plant, a subsidiary of PetroChina Southwest Oil & Gasfield Company, plays a critical role in achieving this production goal. Here, Vertiv has equipped the plant’s vital power systems with an “uninterruptible heart” using its safe and reliable industrial solutions. When national energy security meets cutting-edge industrial technology, how is this “hardcore” collaboration redefining industry benchmarks?
Natural Gas Purification: A Key Link in the “Race to 50 bcm”
With China’s natural gas external dependence exceeding 40%, “the energy饭碗 must be held firmly in our own hands” — this is not just a slogan, but the ultimate mission behind Southwest Oil & Gas Field’s “50 bcm production target.” Over the past decade, the field has accelerated gas production at an unprecedented pace — exceeding 30 billion cubic meters in 2020 and 40 billion cubic meters in 2023. Now, the “50 bcm target” is set to rewrite the speed record once again, reducing the time to add another 10 billion cubic meters to just two years.
As a key infrastructure pillar, the Ziyang Natural Gas Purification Plant holds several winning strategies in the “decisive battle for 50 bcm”:
The largest single-train sour gas purification plant in China, built with the highest level of modularization
Strengthening the foundation for high-quality production increases and supporting the clean energy supply system in the Sichuan-Chongqing region
Undertaking the critical task of delivering purified gas — connecting the surging output of the gas fields on one end and the daily needs of millions of households on the other
The success of the Ziyang Natural Gas Purification Plant directly impacts Southwest Oil & Gas Field’s goal of increasing natural gas production by 2025.
The “Race to 50 bcm” Demands Both Reliability and Speed
The Ziyang Natural Gas Purification Plant processes 4 billion cubic meters of feed gas annually, with each single train treating 7.2 million cubic meters of sour gas per day. The plant deploys a large number of automated and intelligent devices.
During the purification and transmission process, even one second of power interruption can cause significant losses — reliability is paramount.
A power outage in the purification unit would instantly deactivate high-value catalysts
A loss of power could cause pressure loss in the transmission pipeline, potentially triggering major safety incidents
The demanding application environment requires UPS performance that approaches “military-grade” standards in the industrial sector
At the same time, the countdown to the “50 bcm target” is underway, putting immense pressure on project construction schedules and leaving an extremely narrow time window. The construction timeline has been significantly compressed, with strict delivery milestones. The project must ensure the continuous and stable operation of existing production systems while seamlessly integrating new production capacity. In addition, a large number of UPS-powered control and instrumentation devices must be commissioned simultaneously. Whether the UPS system can be started and provide stable power on schedule has become a critical factor influencing overall project progress and successful production launch.
Dynamic Response & Static Protection: Vertiv’s Dual-Dimensional Reliability Design for Industrial UPS
Faced with the harsh conditions of natural gas purification and transmission, Vertiv’s high-reliability industrial UPS delivers outstanding performance that fully meets the extreme requirements of the Ziyang plant.
Proven power technology platform
Excellent industrial adaptability and superior dynamic parameters
Independent air duct design to prevent high dust ingress
High protection rating suitable for the plant’s high-temperature, high-humidity, and corrosive environment
Rapid Response & Ultimate Delivery: Setting a New Industry Standard in 7 Days
Leveraging its highly efficient supply chain, Vertiv delivered equipment to the project site rapidly. Despite the absence of commercial power on site and the extreme challenge of “commissioning while constructing,” Vertiv completed the installation of all UPS main units, power distribution cabinets, and batteries within just seven days. The system was started using battery power alone, providing electricity for the commissioning of downstream control and instrumentation equipment. This perfectly met the customer’s stringent requirement for fast delivery and set a new industry benchmark for delivery speed.
Battery cold start facilitated the commissioning of downstream automation systems, laying the foundation for schedule compression
Equipment commissioning and power‑up completed in one day
Successful first‑time startup, ensuring schedule reliability
Graphical human‑machine interface for easy and quick product operation mastery
As the clarion call for “50 bcm production” resounds across the Bashu region, Vertiv, with its hardcore technology and exceptional service, has added a brilliant chapter to China’s energy security strategy. Vertiv’s high‑reliability industrial UPS acts as an “energy guardian,” injecting a “super‑strong power gene” into the natural gas purification and transmission operations of Southwest Oil & Gas Field with its high reliability and high protection rating.
