Customer Case | Deep rooted in the Petroleum & Petrochemical Sector, HUILIN Nitrogen Generators Fully Support CNPC’s Global Projects

China National Petroleum Corporation (CNPC) is a world‑leading comprehensive energy enterprise whose business covers the full industrial chain including global oil exploration and development, refining and processing, oil‑gas storage, energy transportation and more, with overseas projects across the globe. It sets extremely stringent access standards for industrial nitrogen‑making equipment in terms of explosion‑proof performance, continuous operation capability, precise purity control as well as energy‑saving reliability.

Nitrogen serves as a core protective gas in petroleum and petrochemical production and operations. It is widely used in key processes such as oil extraction, crude oil processing, inert gas protection for oil‑gas storage tanks, pipeline purging, explosion prevention and flame retardancy, and nitrogen injection for production enhancement in low‑permeability oil reservoirs. It acts as critical supporting equipment to guarantee safe production of petroleum projects, boost extraction efficiency and mitigate safety risks.

Drawing on over ten years of R&D and manufacturing experience in air separation equipment, Guangzhou HUILIN Air Separation Equipment Co., Ltd. has forged deep expertise in the petroleum and petrochemical industry. Focusing on the R&D, production and on‑site service of customized industrial nitrogen generators, the company has been listed in CNPC’s qualified supplier directory thanks to stable equipment performance, rigorous quality control systems and customized solutions tailored to special working conditions of the industry. It has become a long‑term strategic supplier of nitrogen‑making equipment for multiple global oil processing, oil‑gas storage and overseas energy projects of CNPC.

To address complex working conditions and large‑scale production demands of CNPC’s oil bases, refineries and oil‑gas storage stations worldwide, HUILIN delivers complete solution sets of industrial‑grade high‑stability PSA Pressure Swing Adsorption nitrogen generators. Equipment has been deployed in batches at domestic and international sites of CNPC for oil processing, oil‑gas storage and oilfield exploitation, fully meeting nitrogen gas requirements across all petroleum and petrochemical application scenarios.

• Stable continuous operation: Equipped with premium core components such as carbon molecular sieves, the equipment features dust and moisture resistance to adapt to harsh outdoor conditions. It supports stable gas production 7×24 hours a day, perfectly matching the round‑the‑clock continuous production needs of petroleum projects and avoiding production disruptions caused by shutdown or gas cut‑off.
• Precise high‑purity gas output: Nitrogen purity can be accurately adjusted according to the requirements of different processes, stably delivering high‑purity nitrogen ranging from 99.5% to 99.99%. It satisfies high‑standard gas demands for multiple scenarios including inert protection for oil and gas, explosion & flame prevention, and nitrogen injection to boost oil reservoir output.
• Explosion‑proof safety adaptation: The complete machine adopts special explosion‑proof design for petroleum and petrochemical applications. Its electrical and control systems comply with industry safety specifications to eliminate potential hazards, making it suitable for flammable and explosive oil‑gas production environments and underpinning safe project operation.
• Energy‑saving, low‑consumption and easy maintenance: Optimized air separation process brings high gas‑production efficiency and low energy consumption, greatly cutting long‑term operating costs for enterprises. Featuring high automation, intelligent one‑key start‑stop and real‑time gas‑production data monitoring, the equipment requires simple maintenance with low failure rates, suitable for large‑scale management of multiple global bases.

HUILIN nitrogen generators have been put into service in batches for CNPC’s major oil processing, oil‑gas storage and oilfield development projects over the years. All units operate stably with qualified gas‑production indicators and reliable safety performance. They effectively safeguard safe production of CNPC projects, help improve oil‑gas extraction efficiency, reduce production energy consumption and avert risks from flammable and explosive substances.

With superior product quality, professional customized solutions and comprehensive global after‑sales support system, HUILIN Air Separation Equipment has won high recognition and long‑term trust from CNPC, and the scale of cooperation between both parties keeps expanding.
