CNG fueling station Components
Fast Fill NGV Refueling Stations include the following basic components:1. Inlet Gas Line (from your local utility) 2. Inlet Dryer - used to reduce water content in the gas 3. Inlet Filtration - filters gas before compression 4. Gas Compressor - elevates inlet gas pressure
from the gas utility to 5,000 psig. 5. Priority/Sequence Panel - allows for temperature compensation of the gas as well as directs gas flow to storage or to vehicle. 6. ASME Storage - stores high pressure gas to be dispensed into vehicles. 7. Gas Dispenser - dispenses gas into the vehicles and measures the amount transferred. 
Some codes to consider: NFPA - 52 and SAE Fuel Specification J1616 |
