LNG Skid Loading Station

Wellhead EPF and Skid‑Mounted LNG Units

Technical Process

Natural gas decarbonization → desulfurization → dehydration → heavy hydrocarbon removal → MRC refrigeration liquefaction process

Technical Advantages

Remote wellheads often face challenges such as geographic isolation and low single‑well gas volumes, making utilization difficult. Direct liquefaction and transportation at the wellhead is one of the most efficient solutions. To address this, YILONG has developed a series of skid‑mounted wellhead gas recovery and liquefaction units that are fast, efficient, and easy to transport.
