Abstract
A compressed natural gas storage and dispensing system having bulk storage tanks in fluid communication with a natural gas supply source; a compressor to produce compressed natural gas; dispensing storage tanks in fluid communication with the bulk storage tanks and in fluid communication with fuel dispensers; a liquified natural gas storage tank in fluid communication with the bulk storage tanks, wherein compressed natural gas resulting from vaporization of the liquified natural gas within the liquified natural gas storage tank is transferred to the bulk storage tanks as a supplemental source of compressed natural gas, or wherein liquified natural gas is vaporized in an ambient vaporizer and delivered to the bulk or dispensing storage tanks.
Claims6
A compressed natural gas storage and dispensing system comprising:
- a CNG bulk storage bank in fluid communication with a natural gas supply source and in fluid communication with CNG fuel dispensers;
- a LNG storage tank in fluid communication with said CNG bulk storage bank, whereby CNG vaporized from LNG retained within said LNG storage tank is delivered to said CNG bulk storage bank;
- a pump in fluid communication with said LNG storage tank, and a vaporizer in fluid communication with said pump and with said CNG bulk storage bank, whereby LNG is pumped from said LNG storage tank to said vaporizer for conversion to CNG and delivery to said CNG bulk storage bank;
- LNG fuel dispensers in fluid communication with said pump, whereby LNG is pumped from said LNG storage tank to said LNG fuel dispensers;
- a heat exchanger in fluid communication with said vaporizer and said CNG bulk storage bank;
- and
- a CNG dispensing storage bank disposed in fluid communication between said CNG bulk storage bank and said CNG fuel dispensers, wherein said vaporizer is also in fluid communication with said CNG dispensing storage bank, whereby CNG from said vaporizer may also be delivered to said CNG dispensing storage bank without passing through said CNG bulk storage bank.
