Whistler Supports PetroChina North China Oilfield Associated Gas NGL Recovery Project in Efficient Commissioning
2025-08-22
On August 16, 2025, the NGL recovery project for associated gas from PetroChina's North China Oilfield, constructed by our company, was successfully put into operation in Xiong'an New Area, Hebei Province. The project employs a modular design, a dual-process coupling technology integrating "DHX + mixed refrigerant cooling," and a one-stop service solution, enabling efficient construction and stable operation.
Modular design enables rapid delivery
The project’s core processing units all adopt a skid-mounted modular structure, including the feed gas separation module, molecular sieve dehydration module, refrigeration separation module, deethanization tower module, and heavy absorption + liquefied gas tower module, among others. These are integrated with utility systems such as the heat transfer oil system, air-nitrogen station, and closed-loop cooling water system. This design significantly shortens the construction timeline, reduces on-site installation complexity, and ensures efficient project progress and rapid delivery.
Dual-process coupling enhances resource recovery rate
Our company's technical team has delved deeply into process optimization, leveraging the unique characteristics of the feed gas composition. We've innovatively adopted a dual-process coupling recovery technology—combining "DHX + mixed refrigerant cooling"—achieving an industry-leading C3+ component recovery rate of up to 95%. This cutting-edge technology not only efficiently produces high-value-added products such as LPG and stable light hydrocarbons but also ensures low energy consumption and environmentally friendly operations, delivering remarkable economic benefits alongside exceptional eco-performance.
One-stop service, comprehensive support from start to operation
From process package development and equipment procurement & manufacturing to on-site installation, commissioning, and startup, our company provides a comprehensive, one-stop solution for this project. Throughout project execution, our team meticulously managed technical details and construction milestones, ensuring high-quality delivery and safe production launch—results that have earned us high praise from both the client and the owner.
The successful commissioning of this project once again highlights Westech's technological expertise and comprehensive service capabilities in the fields of natural gas processing and NGL recovery. Moving forward, our company will continue to drive process innovation and technological upgrades, delivering more efficient, cost-effective, and environmentally friendly energy solutions to our customers.
