CNG mother station compressors are built where natural gas pipelines pass through, drawing gas directly from the pipelines. Natural gas undergoes desulfurization, pressure regulation, metering, filtration, and dehydration processes before entering the compressor unit. It is then compressed, cooled, and purified to a pressure of 25 MPa, and finally dispensed to high-pressure trailers via refueling columns and to vehicles via vending machines. Our company provides turnkey projects.
Equipment Components: Inlet air filtration, pressure regulation, and metering device; desulfurization tower; low-pressure dehydration device; reciprocating compressor; sequential control panel; gas cylinder group; refueling machine; refueling column; CNG trailer; gas alarm device, etc.
This series of equipment occupies approximately 2000~4000 m², with an optimal transportation radius of 150 km and a suitable scale ≥40000 Nm³/d. Installation takes approximately 30 days.
