CNG Daughter Station Compressor

The CNG sub-station is built in a place where no natural gas pipeline passes through. The gas is transferred from the parent station to the station through a CNG trailer. The gas is unloaded through the gas unloading column, and the gas vending machine is used to refill the car.
Equipment composition: gas unloading column, sub-station compressor, sequence control panel, gas storage bottle group, gas dispenser, gas alarm device, CNG trailer and other equipment.
Working method: After natural balance, direct air intake compression and boosting, the average working capacity is more than 1,000 cubic meters
Compressor displacement range changes with trailer pressure drop: 1800-400Nm3/h

A CNG (Compressed Natural Gas) Daughter Station Compressor is a key component found at daughter stations within the CNG supply chain. Daughter stations are smaller facilities that receive compressed natural gas from a central or mother station and further distribute it to end-users or smaller satellite stations. The compressor at a CNG Daughter Station is responsible for maintaining the appropriate pressure levels for local distribution and refueling purposes.

Here are key features and functions associated with a CNG Daughter Station Compressor:

  1. Gas Decompression: The CNG received from the mother station is often at a higher pressure to facilitate long-distance transportation. The compressor at the daughter station may decompress the gas to levels suitable for local distribution and vehicle refueling.
  2. Pressure Regulation: The compressor regulates the pressure of the natural gas, ensuring that it meets the requirements for safe and efficient use in vehicles. This is a crucial step to match the needs of the local distribution network.
  3. Distribution to Dispensers: The compressed natural gas is distributed to dispensers at the daughter station through the compressor. These dispensers are where vehicles connect to refuel with CNG.
  4. Safety Measures: As with any compressed gas facility, safety is a top priority. The compressor at a CNG Daughter Station incorporates safety features to prevent over-pressurization, leaks, and other potential hazards.
  5. Monitoring Systems: Advanced compressors may include monitoring systems to track and control various parameters, such as pressure levels, temperature, and operational status. This ensures the efficient and safe operation of the compressor.
  6. Integration with Station Infrastructure: The compressor is integrated into the overall infrastructure of the daughter station, working seamlessly with other components to provide a reliable and continuous supply of compressed natural gas.

CNG Daughter Station Compressors play a vital role in the decentralized distribution of compressed natural gas, allowing for efficient and convenient access to this clean and sustainable fuel source in various localities. Their proper functioning contributes to the accessibility and reliability of CNG for end-users and various applications.
