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.
Claims16
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 tank, whereby CNG vaporized from LNG retained within said LNG storage tank is delivered to said CNG storage bank.
A method of refilling CNG adapted motor vehicles comprising the steps of:
- providing a CNG storage and dispensing system adapted to deliver CNG to motor vehicles, the system comprising a plurality of bulk storage tanks in fluid communication with a natural gas supply source;
- a plurality of dispensing storage tanks in fluid communication with said bulk storage tanks and in fluid communication with fuel dispensers;
- at least one secondary compressor receiving said natural gas from said bulk storage tanks, compressing the natural gas to a desired pressure to produce CNG, and delivering said CNG to said dispensing storage tanks;
- providing a LNG storage tank in fluid communication with said bulk storage tanks, storing LNG in said LNG storage tank, and allowing said LNG to vaporize within said LNG storage tank to produce vaporized CNG;
- transferring said vaporized CNG to said bulk storage tanks;
- and
- delivering CNG from said dispensing tanks to said fuel dispensers and refilling the motor vehicles.
