Virtual Gas Pipeline Architecture: Setting Up High-Efficiency Mother-Daughter CNG Networks
1. What is a Virtual Gas Pipeline?
Physical pipeline infrastructure is capital-intensive, slow to build, and often economically unviable for remote industrial zones, isolated power plants, or emerging city gas distribution networks. A Virtual Gas Pipeline replaces buried steel pipelines with an agile road-transport network using high-capacity mobile cascades filled with Compressed Natural Gas (CNG) at 250 bar.
2. The Mother Station: Gas Compression & Dispatch Hub
Located directly adjacent to a high-pressure natural gas trunkline, the Mother Station serves as the compression and fleet loading terminal. Key engineering elements include:
-
Inlet Gas Treatment: Coalescing filter-separators remove liquid condensates, followed by molecular sieve desiccant dehydration to achieve dew points below -65°C.
-
High-Throughput Compressors: Heavy-duty reciprocating compressor skids (1,000 - 3,500 Nm³/hr) elevating gas from pipeline pressure (1.5 - 30 bar) to 250 bar.
-
Multi-Bay Loading Gantry: Fast-filling loading arms equipped with dry-break emergency release couplings and automated mass-flow custody metering.
3. The Daughter Booster Station: Gas Extraction & Utilization
A common operational issue in early virtual pipelines was stranded gas—when a cascade trailer drops to 150-180 bar, natural flow into 200 bar vehicle cylinders ceases, leaving 30% to 40% of cargo trapped.
The Hydraulic Booster Solution:
JASA Energies integrates intelligent hydraulic booster compressors at Daughter Stations. As mobile cascade pressure drops, the booster draws suction pressure down to 20 bar and recompresses it to 250 bar, extracting over 95% of total trailer capacity before return dispatch.
