CNG  - Natural Gas Fast-Fill Station 

Below are the components that make up a CNG fueling station and what a typical fast-fill station would include.

CNG Fast Fill  fueling station Components

The basic quick fill station will take pipeline quality gas delivered at 5 psig and pump it up to 5,000 psig for ground storage. The major components of the station include, from gas company connection to the vehicle, the following:   

Fast Fill Natural Gas  Refueling Stations include the following basic components:

1. Inlet Gas Line (from your local utility)

2. Inlet Dryer -used to reduce the moisture content of the gas. Pipeline quality gas typically has a moisture content of 7#mmscf. This must be reduced in order to meet the Society of Automotive Engineers fuel spec J1616.

3. Inlet Filtration - used to filter out any dirt or pipe scale.

4. Natural Gas Compressor - This is really the heart of the system. An Ingersoll Rand compressor package includes the compressor, an electric motor, motor starter, cooler and controls. The compressor package will increase the inlet pressure from 5 psig up to 5,000 psig.

5. Priority/Sequence Panel -   A valve panel that directs the gas flow to either high pressure storage or directly to the vehicle. This panel also insures temperature compensated fills.as well as directs gas flow to storage or to vehicle.

6. ASME Storage - typically ASME vessels rated to hold natural gas at 5,000 psi where it is held until a vehicle is connected to the station.

7. Gas Dispenser - dispenses gas into the vehicles and measures the amount transferred.
