Hot Off the Press: Daqing Oilfield's Landmark 200 MMSCFD TEG Unit Nears Completion in Sichuan

The 200 MMSCFD TEG dehydration unit for Daqing Oilfield’s LNG liquefaction plant in Wusheng County, Guang’an, Sichuan, is now in final installation stages. Slated for July delivery after March production commencement, this project—one of China’s largest onshore gas hubs—leverages triethylene glycol (TEG) absorption technology to strip moisture from natural gas, ensuring pipeline integrity and meeting LNG feedstock specs. The timing aligns with Daqing’s recent breakthrough in heavy oil dehydration (costs slashed by 80% via thermo-electrochemical processes)5, spotlighting its dual focus on conventional and unconventional resource optimization.

Why TEG Dominates:

• Efficiency & Scalability: TEG units achieve dew points below -40°C, critical for liquefaction.
• Market Surge: Global TEG dehydration sales hit $874M in 2024, projected to reach $1.3B by 2031 (6.2% CAGR). China leads APAC demand, driven by shale gas and LNG expansions.

Industry Outlook:

With SLB, CECO, and Sichuan Goldstar dominating supply chains, Daqing’s Wusheng project sets a precedent for modular, high-capacity deployments. As operators prioritize OPEX reduction—emulating Daqing’s “*3-year maintenance, 20-year lifespan*” TEG design—the tech’s adaptability to offshore and remote sites will accelerate adoption.

The Bottom Line:

Daqing’s Sichuan triumph isn’t just a project milestone—it’s a blueprint for China’s gas infrastructure sovereignty. Watch for TEG innovations (e.g., sub-25mg/Nm³ glycol loss systems) to dominate next-gen decarbonization hubs.
