Abstract
Systems and methods are provided for a combined defuel and priority panel for a fueling station. The defuel and priority panel is configured to defuel a compressed natural gas (CNG) vehicle and direct the defueled gas to fuel other CNG vehicles at the panel fueling and defueling site. The defuel and priority panel is also configured to store defueled gas in defuel storage tanks, which can then be used to later fuel CNG vehicles.
Claims25
A defueling system comprising
- a compressor inlet;
- a defuel inlet for connecting to and defueling a pressurized fuel source having a pressure;
- a heat exchange system connected to the defuel inlet, wherein the heat exchange system is configured to prevent freezing during defueling;
- a pressure regulator;
- a defueling storage tank having a pressure Spsi for storing defueled fuel from the pressurized fuel source,
- wherein the pressure regulator is configured to depressurize a compressed gas being defueled from the pressurized fuel source, and
- wherein the defueling system comprises either a refueling outlet configured to refuel a fuel demand source with defueled fuel, a defuel storage for storing defueled fuel, or both.
The defueling system claim of 19, wherein the defueling system is configured to vent some or all of the gas from the fuel source via a defuel vent valve.
The defueling system claim of 21, wherein the defueling system is configured to allow a user to select automatically or manually venting the via the defuel vent valve.
The defuel system claim of 1, further comprising a control system configured with control logic that, when executed by a control system, allows for automated and manual operation of the system.
The defuel system claim of 24, wherein the control system comprises control logic configured to, when executed by a processor of the control system, allow the fuel to free flow to available fuel demand sources before commanding a compressor to run.
