Yibai Natural Gas Dehydration System Collaboration Case with CNPC North China Oilfield

Project Background:

A gas gathering station operated by CNPC North China Oilfield faced challenges including high natural gas water content (saturated state) and excessive solid particle impurities, compromising downstream pipeline transportation and compressor unit operational safety. Yipai developed a customized integrated intelligent dehydration and filtration solution for the facility.

Technical Solution Highlights:

Three-stage treatment process:

Cyclone separation → High-efficiency coalescing filtration → Molecular sieve deep dehydration

Integrated AI control system automatically adjusts processing parameters

Key Performance Indicators:

Processing capacity: 200,000 m³/day

Exit water dew point: ≤-40°C (original condition: -15°C)

Solid particle filtration precision: 0.1μm

Pressure Drop Control: <0.05MPa

Implementation Outcomes:

Dehydration efficiency increased by 300%, reducing annual pipeline corrosion maintenance costs by 2.8 million yuan

Filter system lifespan extended to 5 years (previous equipment required replacement every 2 years)

Achieved unmanned remote monitoring, reducing manual inspection frequency by 80%

Industry Demonstration Value:

This case has become a benchmark project for CNPC’s “Smart Gas Field” initiative, subsequently replicated across six gas gathering stations in North China Oilfield. Yibai’s proprietary “Dehydration-Filtration-Smart Monitoring” modular design has now set a new industry standard.
