Compressed Natural Gas Storage and Dispensing System

摘要

A compressed natural gas storage and dispensing system having descending pressure bulk storage banks in fluid communication with a supply source for CNG and high pressure storage banks in fluid communication with the descending pressure bulk storage bank, both banks being in fluid communication with fuel dispensers, wherein the delivery pressure of the CNG during simultaneous refueling of CNG powered vehicles is equalized.

1. A compressed natural gas (CNG) storage and dispensing system comprising:
a descending pressure bulk storage bank in fluid communication with a natural gas supply source; a high pressure storage bank in fluid communication with said descending pressure bulk storage bank; at least one dispenser adapted to refuel a CNG powered vehicle, each said at least one dispenser in fluid communication with said descending pressure bulk storage bank and with said high pressure storage bank; and a re-compressor in fluid communication with said descending pressure bulk storage bank and said high pressure storage bank, whereby CNG is delivered from said decreasing pressure bulk storage bank to said high pressure storage bank as needed to refill said high pressure storage bank.
