Abstract
Systems and methods are disclosed that may be configured for transferring a fluid. The fluid may be transferred from a fluid source by which the fluid is under a first differential pressure to a container via use of a pressurizer that can increase the pressurization of the fluid to a second differential pressure. A controller may be used to coordinate operations of various components to allow the pressure generated by the pressurizer to be used to augment the pressure generated by the first differential pressure. Additional embodiments may include use of a mobile fueling unit that may facilitate transfer of the fluid from the container to a vehicle.
Claims22
A fluid transfer system, comprising:
- a receiving location comprising a first processing means to receive a fluid from a sourcing location via a first differential pressure provided by the sourcing location;
- a container configured to receive the fluid from the receiving location via the first differential pressure until the fluid within the container reaches a first pressure and/or a first temperature;
- and,
- the first processing means further comprising a pressurizer to increase a pressure of the fluid so that a second differential pressure is generated between the receiving location and the container, the second differential pressure causing the fluid to transfer into the container until the fluid within the container reaches a second pressure and/or a second temperature.
1 more element
A mobile fueling unit, comprising:
- a container configured to receive and dispense a fuel gas, the container further configured to be transported by a vehicle;
- and,
- a compressor affixed to the container, the compressor configured to be driven by an engine operable by the fuel gas, the compressor in fluid transfer with the container to facilitate flow of the fuel gas from the container to a vehicle.
A method of fluid transfer, comprising:
- receiving, at a receiving location, a fluid from a sourcing location, the sourcing location providing a first differential pressure to cause the fluid to flow;
- receiving, at a container, the fluid from the receiving location by means of the first differential pressure until the fluid within the container reaches a first pressure and/or a first temperature;
- and,
- increasing the pressure of the fluid via a pressurizer so that a second differential pressure is generated between the receiving location and the container, the second differential pressure causing the fluid to transfer into the container until the fluid within the container reaches a second pressure and/or a second temperature.

A method of fluid transfer, comprising:
- receiving, at a filing station, natural gas from an interstate/intrastate transmission main via a processing means of the filing station, the processing means comprising a meter and regulation unit configured to receive the natural gas from the interstate/intrastate transmission main, a terminal unit comprising a first compressor configured to selectively transfer the natural gas to a fill post, and a pipeline configured to facilitate transfer of the natural gas from the meter and regulation unit to the terminal unit;
- controlling, via a programmable logic controller, the natural gas flow by allowing a first differential pressure of the interstate/intrastate transmission main to cause the natural gas to transfer from the interstate/intrastate transmission main to the meter and regulation unit;
- selectively controlling, via the programmable logic controller, the natural gas flow by first allowing the first differential pressure to cause the flow of the natural gas from the meter and regulation unit, through the pipeline, through the terminal unit, through the fill post, and into a container until the natural gas within the container reaches a first pressure and/or a first temperature, and then by causing the first compressor to increase the pressure of the natural gas so that a second differential pressure is generated between the first compressor and the container to cause more natural gas to flow from the terminal unit, through the fill post, and into the container until the natural gas within the container reaches a second pressure and/or a second temperature, the second differential pressure being greater than the first differential pressure, the second pressure and/or the second temperature being greater than the first pressure and/or first temperature;
- measuring, via the programmable logic controller, the pressure and/or temperature of the natural gas within the container;
- diverting, via the programmable logic controller, at least some of the natural gas to a natural gas generator to selectively generate augmented electrical power, the augmented electrical power being selectively transferred to the first compressor, the generator selectively generating the augmented electrical power and selectively transferring the augmented electrical power to the first compressor only when the first compressor is increasing the pressure of the natural gas;
- selectively transferring the natural gas from the fill post and into a vehicle;
- transporting the container via the vehicle from the filling station to a delivery site;
- transferring the natural gas from the container to a user, the transferring comprising depressurizing the natural gas to a third pressure, the third pressure being less than the second pressure;
- tracking at least one of the container and the vehicle via a computer system, the tracking comprising reading at least one RFID tag attached to the container and/or the vehicle via at least one RFID reader, the RFID reader being in electrical communication with the computer system;
- and
- configuring at least one container to have a second compressor and being in fluid communication therewith, driving the second compressor by an engine operable by the natural gas within the container to cause transfer of the natural gas from the container to a fleet vehicle.
