About this product
Product information from the supplier.
Product Overview
Our CNG Decompression Equipment is engineered to meet the evolving energy demands and environmental standards of modern natural gas distribution. By facilitating the secure storage and transport of high-pressure Compressed Natural Gas (CNG), this system enables efficient delivery to end-users through advanced multi-stage heat exchange and precise pressure regulation, ensuring a seamless transition from transport tankers to pipeline networks.
Designed for optimal economic efficiency, the system is ideal for supply ranges between 300km and 500km, serving 2,000 to 4,000 households with a flow capacity of 200-5,000Nm³/h. This modular solution offers a low investment threshold, short construction periods, and rapid ROI, while serving as a critical peak-load and emergency gas source for future long-distance pipeline expansions.

Frequently Asked Questions
Q: What is the primary difference between secondary and third-stage pressure regulation?
Secondary regulation reduces pressure in two steps (e.g., to 1.0-4.0MPa then 0.1-0.4MPa), while third-stage regulation adds an intermediate step (3.0-7.5MPa to 1.6-2.5MPa then 0.1-0.4MPa) for more precise control and stability in higher-capacity systems.
Q: Why is heat exchange necessary during CNG decompression?
Rapid decompression causes a significant drop in gas temperature (Joule-Thomson effect). Heat exchangers are used to preheat the gas to prevent equipment freezing and ensure the outlet temperature remains between 10-20°C.
Q: What is the ideal supply scale for these CNG stations?
The system is most economic when serving 2,000 to 4,000 households with an air supply range of 200-5,000Nm³/h, typically within 300-500km from the source.
Q: How is the system's safety ensured during high-pressure unloading?
Safety is maintained through high-pressure emergency cutoff valves, relief valves, and a central control console that manages interlocking controls for all key valves and pressure levels.
Q: Can this equipment be used as a temporary solution?
Yes, due to its low investment and quick installation, it is an excellent choice for temporary supply or as a peak-load and emergency gas source before a permanent long-distance pipeline is established.
Q: What components are included in the standard CNG station structure?
A standard station includes an unloading system, pressure regulating heat exchange system, flow metering system, central control system, and a heating system (boiler and pumps).
