CNG gas supply overall solution


CNG减压站


CNG is a process where natural gas from pipeline transportation or gas Wells is filtered, desulfurized, and dehydrated, and then compressed (at 20Mpa) into CNG high-pressure transport skids. The skids then transport the compressed natural gas to gas-consuming units where the gas pipeline network cannot be temporarily laid. Through processes such as unloading, filtration, heat exchange (above the second stage), pressure regulation, metering, and deodorization, natural gas of appropriate pressure is delivered to gas users. The process of reducing the pressure of high-pressure natural gas is an endothermic process. If the heat exchange is insufficient, frost or ice blockage will occur in the pipeline, seriously affecting the safety of the pressure reduction equipment and the pressure reduction process. Therefore, heat exchange must be carried out before pressure reduction. Depending on the on-site conditions, options such as hot water heat exchange, electric heating heat exchange, and steam heating heat exchange can be selected.

Core advantages: Dual-path gas supply redundancy design, large-flow pressure reducing equipment, multi-level pressure stabilizing system, combined with large-capacity gas storage facilities, eliminating pressure fluctuations and gas interruption issues, suitable for industrial high-load and uninterrupted gas usage scenarios.

Equipped with a fully automatic intelligent PLC control system.

- Real-time monitoring of station pressure, temperature, flow rate, and equipment operation status, with real-time data display, automatic storage, and traceable query;

- Automatic alarms for overpressure, underpressure, leakage, low temperature, and equipment failures, and simultaneous triggering of emergency shut-off valves, automatic gas cut-off for safety precautions;

- Automatic switching of dual equipment, intelligent start-stop, automatic adjustment of supply gas flow according to gas usage load, energy saving and consumption reduction;

- Support for remote monitoring, remote parameter debugging, data upload, and compatibility with smart energy management platforms;

- Features include power-off protection, fault memory, and automatic reset functions to ensure stable system operation.
