In one aspect, the filter 140 is an 80-micron particulate filter. The filter 140 can remove various contaminants, including but not limited to scale, mud, and debris.
Fuel from the filter 140 is then fed into a second filter 145. The second filter 145 removes a second amount and/or a second type of contaminants from the fuel. In one aspect, the second filter 145 is an organic filter. The second filter 145 can be configured to remove contaminants including but not limited to bacteria and mold.
One or more pumps P are positioned to move the fuel through the fuel system 11. The pumps P can be configured to provide a fuel flow rate as needed to move the fuel through the fuel system 11. The pumps P can be the same or different, and can provide for the same or different flow rates.
Filters 150 are configured to remove additional contaminants from the fuel that were not previously removed. In one aspect, the filters 150 are separating filters that separate water from the fuel. The filters 150 can include a coalescing filter element that removes the water from the fuel. The filters 150 can also be water absorbing filters that absorb the water in the fuel.
Fuel from the filters 150 moves through a Y-connector 160 and includes a single outlet that forms a single stream. The fuel can then be output through a dispensing end 170 equipped with a hose and nozzle. The fuel can also be directed by a valve 175 through a line 180 and back into the tank 20.
One or more sections of the fuel system 11 can include redundant components. In the event a section of the system 11 fails, fuel can still be processed through the remaining section.
The control system 100 as schematically illustrated in
The sensors 104 can be positioned at various locations throughout the fuel system 11. The sensors 104 can detect various aspects of the fuel and/or fuel system 11, including but not limited to the flow rate, amount of fuel in the tank 20, status of one or more of the filters 140, 145, 150, and contaminants in the fuel. Signals from the sensors 104 are received by the processing circuit 102 that calculates the various values. One or more of the sensors 104 can also detect environmental conditions of the environment and/or the fuel. This can be used by the processing circuit 102 to determine fuel status. Detected aspects include but are not limited to the temperature at the trailer 10, the temperature within the fuel tank 20, the temperature of the fuel at one or more locations along the fuel system 11, and the humidity at the trailer 10.
The processing circuit 102 can polish the fuel in the event the fuel has been stored within the tank 20 for an extended period of time. For example, this can occur when the trailer 10 is positioned at a remote location such as a remote outpost in which the demand for fuel is low. Another example is when the trailer 10 is filled with fuel and positioned in preparation for an event (but not yet in use), such as for emergency management scheduling. One specific example is a trailer 10 that stores fuel and is positioned in the field in anticipation of a possible hurricane strike. Another example is a trailer 10 with fuel that is housed at a relatively remote airport that does not see regular air traffic.
The trailer 10 can be configured to periodically move the fuel through the fuel system 11. This maintains the fuel in a usable state for when it is needed by a vehicle. The trailer 10 can move the fuel on a regular basis (e.g., every day, every week), after the fuel temperature has been elevated above a predetermined threshold, as well as immediately before a fueling event.
One or more sensors 104 detect the amount of fuel that is moved through the fuel system 11. The processing circuit 102 receives the signals and determines whether to continue moving the fuel through the fuel system 11. This can include moving a predetermined amount of fuel through the fuel system 11, or sensor readings that indicate the fuel being in at or above a predetermined threshold.
The processing circuit 102 controls the movement of the fuel. This can occur during dispensing of the fuel through the dispensing end 170 or returning the fuel to the tank 20 through the return line 180.
The trailer 10 can also process fuel from other sources.
The sensors 104 detect the fuel entered through the input line 190. This can include the amount of fuel entered into the fuel system 11 and/or contaminants that are in the fuel. Further, one or more sensors 104 can be positioned along the input line 190 to detect the fuel prior to entry into the fuel system 11. In one design, the processing circuit 102 receives the signals and determines the contaminants in this fuel. In the event the contaminants are above a threshold amount, the processing circuit 102 can stop the inputting and prevent additional fuel from being input into the fuel system 11. This can include shutting off the one or more pumps P.
In one design, the processing circuit 102 can determine that additional filtering is required of the fuel that is being input through the line 190. This can be based on readings from one or more sensors 104 positioned downstream from the input line 190. The fuel can be diverted at the valve 175 at the downstream end of the fuel system 11 and into the return line 180. Valve 177 located along the return line 180 can direct the fuel through the fuel system 11 downstream from the tank 20 for additional filtering. This further prevents the fuel that needs additional processing from being input into the fuel tank 20 and potentially contaminating the stored fuel.
The processing circuit 102 is configured to communicate with vehicles in need of fuel. This can include communications with incoming vehicles, such aircraft in the area in need of fuel or an approaching ground vehicle. When necessary, the processing circuit 102 can begin necessary prep work for the fuel to be ready for dispensing while the vehicle is approaching. The fuel is then ready for dispensing once the vehicle arrives at the trailer 10.
If the fuel is not ready for dispensing, the processing circuit 102 determines the amount of time necessary to prepare the fuel (block 355). This can include the amount of time necessary to move the fuel through the fuel system 11. The time when the fuel is available for dispensing is transmitted to the vehicle (block 356) who responds with confirmation that the fuel is needed or that the fuel is not needed (block 357). If the fuel is not needed, the trailer 10 stops (block 358). If the fuel is needed, the fuel is moved through the fuel system 11 (block 359). This can include moving the fuel through the fuel system 11 a predetermined number of times. This can also include processing the fuel until readings from one or more sensor 104 indicate that the fuel is in condition for dispensing.
The processing circuit 102 determines that the vehicle has arrived at the trailer 10 (block 360). This can include a person entering a passcode into the input device 208 of the control system 100, or activating the fuel system 11. The fuel is then dispensed through the dispensing end 170 (block 361).
The trailer 10 can be configured such that the fuel is maintained in a ready state. This includes the fuel being periodically moved through the fuel system 11. This movement can occur on a scheduled basis, such as every day, week, etc., or can occur when the processing circuit 102 determines this is necessary based on readings from one or more sensors 104. As the fuel is in a ready state, the processing circuit 102 can determine just whether the requested amount of fuel is available to a vehicle when a fuel request is received. It is not necessary for the processing circuit 102 to determine the state of the fuel.
The trailer 10 can be configured to receive fuel requests directly from vehicles. The trailer 10 can also be configured as part of a larger network of trailers 10 that extend over an enlarged area. A central controller 400 is configured to communicate with the trailer 10. The central controller 400 can simply monitor the trailer 10 or can schedule fuel activities of the trailer 10.
A communication interface 405 is configured to exchange signals with one or more vehicles and trailers 10. The communication interface 405 can comprise an electronic transmitter for transmitting radio, electrical, and/or optical signals, and can further comprise an electronic receiver for receiving radio, electrical, and/or optical signals. In some embodiments, the communication interface 405 is configured to support short-range wireless signaling via BLUETOOTH, RFID, ZIGBEE, and/or WIFI. The communication interface 405 can additionally or alternatively be configured to support long-range wireless communication via cellular- and/or satellite-based signaling. The communication interface 405 can additionally or alternatively be configured to support signaling over a wired connection, such as a serial, USB, micro USB, FIREWIRE, Lightning, and/or Thunderbolt connection. There can be more than one communications interface 405. In such embodiments that support radio communication, an antenna (not illustrated) can be configured for the transmitting and receiving of wireless signals to and from the remote sources. The controller 400 can also include a clock 406 to measure various timing aspects.
The communication interface 405 can include a web interface for users to access their account and obtain various information. The web interface can support a website through which the contents of the database 407 are accessible. In one or more embodiments the web interface provides browser-based access to the contents of the database 407. The different users can login to the browser-based interface and access the pertinent usage information as well as schedule fuel dispensing. The browser-based interface can support well-known browsers such as Internet Explorer and Mozilla Firefox, Safari, Chrome.
Alternatively, the different users can obtain information from the database 407 using one or more Application Programming Interfaces (APIs) through a user device. Also, in one or more embodiments the web interface supports access to the database 407 using web services in addition to, or as an alternative to, the browser-based interface.
The controller 400 can monitor the status of the one or more trailers 10. For each trailer 10, this can include monitoring the amount of fuel, the amount and times of dispensed fuel, and information about the fuel (e.g., recent fuel contamination results based on sensor readings, when the fuel has been moved through the fuel system 11, etc). The controller 400 can also track when fuel has been added to the trailer 10 during a refueling event.
The controller 400 can also control the coordinated activities of the network of trailers 10. The controller 400 can receive fuel requests from the vehicles and schedule the trailers 10 for fueling. This can include the controller 400 monitoring the status and the amount of fuel at the trailers 10. Based on this information, the controller 400 is able to direct the vehicles to one of the trailers 10 that is able to provide the fuel.
The controller 400 determines which trailer 10 to direct the vehicle to for dispensing of the fuel (block 551). This location can be based on the location of the vehicle when the request is received and the amount of fuel requested. The controller 400 can determine the closest trailer 10 to the vehicle at the time the request was received. The controller 400 can also determine a more distance trailer 10, such as one with a larger fuel capacity in the event additional fuel could be necessary. The location of the trailer 10 is then transmitted to the vehicle (block 552). This can include the geographic location as well as any particular instructions for reaching the vehicle. This can also include specific information to dispense the fuel, such as a passcode to activate the fueling system 11 to dispense the fuel.
After the fuel has been dispensed to the vehicle, the controller 400 receives dispensing information (block 554). This information can be received from the trailer 10 and/or the trailer that received the fuel. The information can include the amount of dispensed fuel, the time the fuel was dispensed, etc. The controller 400 receives the information and updates the fuel information about the trailer 10 for future purposes.
When the amount of fuel remaining in a trailer 10 falls below a predetermined amount, the controller 400 can schedule additional fuel to be delivered to the trailer 10. In this manner, the controller 400 is able to maintain the full network of usable trailers 10 that are available for fuel.
The controller 400 can also monitor the condition of the fuel system 11 within the trailer 10. This can include the length of time the various components have been in use in the trailer 10, and the amount of fuel that has been filtered by the fuel system 11. The controller 400 can also receive signals from one or more of the sensors 104. The controller 400 can use this information to schedule maintenance of the trailer 10 as necessary. In the event the controller 400 determines an issue, the controller 400 can place the trailer 10 out of service and prevent fuel dispensing until the issue has addressed by a technician.
The trailer 10 can include one or more control systems 100. One design includes a single control system 100 that oversees the functionality. Other designs include two or more separate control systems 100. Each control system 100 can be configured to control the functionality of a different aspect of the trailer 10. In one example, a first control system 100 oversees the polishing aspects of the fuel, and a second control system 100 communicates with the controller 400.
Different devices 10 can be used to store and transport fluid according to aspects of this disclosure. A trailer 10 is one example of a device 10. Another device 10 includes a skid device that includes rails or a platform on the bottom that contacts against and is pulled over the ground.
Spatially relative terms such as “under”, “below”, “lower”, “over”, “upper”, and the like, are used for ease of description to explain the positioning of one element relative to a second element. These terms are intended to encompass different orientations of the device in addition to different orientations than those depicted in the figures. Further, terms such as “first”, “second”, and the like, are also used to describe various elements, regions, sections, etc. and are also not intended to be limiting.
