Do You Know About Pressure Reducers?
CNG, also known as Compressed Natural Gas, is the most ideal energy source, and its application technology has become increasingly mature after decades of development. It has the characteristics of low cost, high efficiency, no pollution, and safe and convenient use. Widely used in urban gas, transportation, and industrial production fields. CNG pressure reducing station refers to a place where compressed natural gas (CNG) is used to provide fuel to urban gas pipelines, natural gas vehicles, and large CNG sub station vehicles. Generally, natural gas is first pre purified to remove sulfur and moisture from the gas, and then the pressure is reduced from 25MPa to 0.1MPa~1.0MPa by a regulator to achieve gas transmission function.
The secondary pressure regulating station is suitable for battlefields with a flow rate of 2000Nm3/h and below.
Three stage pressure regulation process: Firstly, high-pressure rubber hoses and quick couplings are used to connect with the pry tank truck. Compressed natural gas enters the first stage heat exchanger through high-pressure ball valves and high-pressure cut-off valves, where it is heated and then depressurized to 3.0MPa-7.5MPa through the first stage pressure regulator. It is then heated and regulated to 1.6MPa-2.5MPa through the second stage heat exchanger and pressure regulator. After three-stage pressure regulation to 0.1MPa-0.4MPa, it enters the flow meter for flow measurement, and finally odorizes the gas before entering the medium pressure pipeline network. The control of various levels of gas pressure, temperature, flow rate, water temperature, key valves, and switching between the two channels in the pressure regulating station are all interlocked and controlled by the central console.
The three-level pressure regulating station is suitable for battlefields with a flow rate of 2000Nm3/h and above. The central console is used for real-time monitoring and control of equipment operation. The pressure regulation process of compressed natural gas is much more complex compared to ordinary pipeline pressure regulation, and it is necessary to use a control panel to monitor the entire pressure regulation process.
