Compressed Natural Gas CNG Compressor CNG Gas Fueling Station Skit-mounted 300Nm3/h to 6000Nm3/h

Quick Detail:

1.CNG Compressor/Natural Gas Compressor/Fueling Station Compressor/CNG gas fueling station

2.CNG gas fueling station,CNG is a transportation fuel made by compressing natural gas or biogas to less than 1% of its volume. Natural gas pipelines transport natural gas to CNG stations where it passes through a gas dryer and is compressed through two to five stages of compression until it reaches a pressure of up to 4,500 psig.

Once compressed, CNG is stored and distributed at a significantly lower cost than gasoline or diesel. The compressed natural gas reaches a priority panel that directs into the on-site, above-ground storage vessels. Customers fill their vehicles from the dispenser, much like a conventional fueling station.

Description:

The CNG compressor is a series of products specifically developed for CNG vehicle refueling stations. The units utilize a reciprocating piston structure and modular design. By combining variations in the unit body and cylinders, multiple models can be derived, covering a wide range of intake pressures (0.1~20 MPa) and gas supply capacities from 300 Nm³/h to 6000 Nm³/h.

All series of CNG compressor units are fully assembled and tested at the manufacturing facility, presenting complete sets that are compact, highly integrated, and equipped with aesthetically pleasing dedicated soundproof enclosures. They can be installed outdoors, featuring a small footprint, simple foundation requirements, easy installation, cost-effectiveness, and quick commissioning.

Cooling options include air-cooling, water-cooling, and hybrid cooling, catering to various types of CNG vehicle refueling stations, conventional stations, mother stations, and substations.

Applications:

CNG compressors play a crucial role in various applications where compressed natural gas (CNG) is used as a fuel or needs to be transported efficiently. Here are some common applications:

1. **CNG Vehicle Refueling Stations:**

- CNG compressors are extensively used at CNG refueling stations to compress natural gas before it is dispensed into vehicles. These stations can be located along highways, in urban areas, or at commercial facilities.

2. **Public Transportation:**

- Many public transportation fleets, such as buses and taxis, use CNG as a fuel source. CNG compressors are employed to provide a reliable and continuous supply of compressed natural gas for these vehicles.

3. **Industrial Applications:**

- Industries may use CNG as a clean and cost-effective fuel for various processes. CNG compressors are used in industrial settings where a compressed natural gas supply is required for manufacturing or power generation.

4. **Commercial Fleets:**

- Some companies operate fleets of CNG-powered vehicles for their transportation needs. CNG compressors enable the efficient refueling of these commercial vehicle fleets, reducing dependence on traditional fuels.

5. **Utilities and Power Generation:**

- CNG can be used as a fuel for power generation in certain situations. CNG compressors are employed to ensure a steady and pressurized supply of natural gas for power plants.

6. **Residential and Commercial Heating:**

- In some regions, CNG is used for residential and commercial heating applications. CNG compressors may be used to provide a compressed gas supply for these heating systems.

7. **Gas Pipeline Maintenance:**

- CNG can be transported through pipelines for distribution. CNG compressors play a role in maintaining the pressure within these pipelines to ensure the efficient and safe transport of natural gas.

8. **Backup Power Systems:**

- CNG can be used as a backup fuel for power generation during emergencies. CNG compressors may be utilized to maintain a pressurized storage of natural gas for these backup power systems.

9. **Mobile CNG Stations:**

- In areas without fixed CNG infrastructure, mobile CNG stations equipped with compressors can be deployed temporarily to provide a convenient refueling option.

CNG compressors contribute to the wider adoption of natural gas as a cleaner and more environmentally friendly alternative to traditional fuels in various sectors.
