Abstract

A method of deploying a water intake device in a fuel storage tank involves providing a water intake device having an elongate flow structure including at least one flexible flow tube and an elongate substrate adjacent to the flow tube, wherein the substrate provides a semi-rigid characteristic that allows the elongate flow structure to be guided. Another step of the method involves providing a guide tube having a straight portion and an arcuate portion at a distal end of the guide tube. Another step of the method involves installing the guide tube generally vertically into a fuel storage tank with the arcuate portion directed toward a desired guidance direction. Another step of the method involves moving the elongate flow structure of the water intake device through the guide tube into a deployed position.

Abstract

A vacuum-actuated shear valve coupled between piping from a storage tank and piping internal to a fuel dispenser that automatically opens and closes in response to a vacuum level. A vacuum actuator is provided to control a fuel flow valve inside the shear valve. When a sufficient vacuum level is generated to the vacuum actuator, the actuator keeps the flow path valve inside the shear valve open. When the vacuum is lost, the vacuum actuator releases the flow path valve inside the shear valve, which closes it. The vacuum actuator is coupled to a secondary containment space of a fuel-handling component that is drawn under a vacuum level by a vacuum-generating source to monitor for leaks. Thus, if a leak occurs in the monitored secondarily contained space, the shear valve is automatically closed to prevent the flow of fuel from continuing to be supplied to the source of the leak.

Abstract

A system and method for automatically adjusting an ORVR-compatible Stage II vapor recovery system to maintain the air-to-liquid (A/L) ratio within desired tolerances or limits to meet regulatory and/or other requirements. An air flow sensor (AFS) or vapor flow meter measures the amount of recovered vapor for a dispensing point to calculate the recovery efficiency of the system in the form of the A/L ratio. Volume or flow rate measurements can be used. ORVR fueling transactions are either minimized or excluded from the A/L ratio, so that the A/L ratio is not artificially lowered due to a blocked or altered recovery. The A/L ratio is then compared to a desired or nominal A/L ratio. Adjustments to the recovery system are made within prescribed safety tolerances if the A/L ratio differs from the desired ratio.

Abstract

A carbon canister to adsorb hydrocarbons from a hydrocarbon air mixture in a UST system to prevent fugitive emissions due to overpressurization. The carbon canister has an inlet port at one end coupled to the UST system. An outlet port on the opposite end of the canister is connected to a flow-limiting orifice with a known calibrated flow rate that vents in a controlled fashion to the atmosphere. When UST pressure rises slightly above ambient pressure, fuel vapors and air from the UST system enters, via the inlet port, into the canister, where hydrocarbons are adsorbed onto the surface of the activated carbon. The cleansed air vents through the controlled flow outlet port to atmosphere, thereby preventing excessive positive pressure from occurring in the UST system. The activated carbon is purged of hydrocarbons by means of reverse air flow caused by negative UST pressures that occur during periods of ORVR vehicle refueling.

Abstract

A fuel quality monitoring system and method to automatically and/or continuously monitor quality of fuel dispensed and control the operation of the fuel dispenser. The control system monitors fuel quality to prevent unsafe refuelings when the fuel quality is unacceptable. In one embodiment, a combination of a differential pressure sensor, a water detector, and/or a particle monitor is employed inline the fuel flow path of a fuel dispenser, and in particular an aviation refueling truck, to monitor the quality of the fuel. If fuel quality is at an acceptable level although not ideal, the control system can allow fueling with the generation of reports and alarms. If the fuel quality is unacceptable, fuel flow can be stopped. If the differential pressure across the filter indicates a high degree of debris and/or water retention, the control system can automatically lower the flow rate to reduce the risk of filter breakdown without completely preventing fueling until the filter can be replaced.

Abstract

A redundant vacuum-generating source system and method for generating and/or maintaining a vacuum level in a secondarily contained fuel-handling component that is monitored for leaks. The vacuum-generating source is coupled to upstream fuel-handling components to draw a vacuum level in their interstitial spaces. Other downstream fuel-handling components are drawn under a vacuum by tapping off of the upstream fuel-handling component's interstitial spaces for convenience. A series of valves control which upstream fuel-handling component's interstitial spaces are coupled to a downstream fuel-handling component interstitial space. In the event that an upstream fuel-handling component contains a leak, a control system can control the valves to switch the vacuum generation of a downstream fuel-handling component to another upstream fuel-handling component that does not contain a leak so that a sufficient vacuum level can be generated in downstream fuel-handling component(s) to monitor it for leaks.

Abstract

An end-of-zone or line sensor placed at the end of a secondarily contained fuel piping(s) or network(s). The interstitial space of the piping network is coupled to a vacuum-generating source that draws a vacuum level in the interstitial space to monitor for leaks or breaches in the piping network. The end-of-zone sensors are coupled to the interstitial space at the far end of the piping network and vacuum-generating source. The end-of-zone sensors actuate when a sufficient vacuum level is detected. A control system monitors the status of the end-of-zone switches. If the vacuum-generating source is activated to draw a vacuum level, and the end-of-zone sensors react to indicate the vacuum level has reached the sensor, the control system knows that there is no blockage over the entire span of the piping network, and thus entire piping network can be properly monitored for leaks.

In general, the STP is comprised of a casing body comprising a check valve extraction housing and the hydraulics cavity. The check valve is located within the hydraulics cavity and is comprised of a check valve stem, an inlet side, and an outlet side. The check valve extraction housing comprises a lock-down screw adapted to attach to the check valve stem and apply a force to the check valve to open the check valve, thereby relieving the pressure differential between the inlet side and the outlet side.

Abstract

A system and method for calculating the flow rate of a dispensing point or flow capacity of a pump and fuel delivery system and determining if the dispensing point or fuel delivery system has a blockage and/or a performance problem if the calculated dispensing point flow rate is other than expected. The calculated dispensing flow rate is calculated by collecting fuel tank level data points for a dispensing point that fall within start and stop events of the dispensing event. The slope of a fitted line to the fuel tank level data points is used as the indication of the flow rate of the dispensing point. Different mathematical techniques may be used to improve the flow rate calculation to compensate for the minimum resolution of collecting fuel tank level data and the dead time included in the data of a dispensing transaction.
