An underground sensing arrangement for use in a fueling environment comprises at least one sensor located under a ground surface and a power supply. The sensor is operative to detect a condition in the fueling environment. A wireless transceiver is in electrical communication with the at least one sensor and the power supply. The wireless transceiver has an environmental housing and electrical circuitry contained within the environmental housing. The electrical circuitry includes control circuitry, radio circuitry, and an antenna. The environmental housing is substantially transparent to electromagnetic frequencies at which the wireless transceiver operates and is potted substantially flush with the ground surface.

A system configured to replace a top portion of an under-dispenser containment unit embedded within a concrete island under a fuel dispenser. The system includes a mounting structure configured to be coupled to the top portion of the under-dispenser containment unit, and a dispenser sump top configured to be coupled to the mounting structure and the fuel dispenser. The mounting structure includes a series of angles and the dispenser sump top includes a frame having a pair of opposing end walls and a pair of opposing sidewalls, a central opening defined by the frame, a splash lip extending outward from a lower portion of each of the pair of opposing ends walls and the pair of opposing sidewalls, and a series of dispenser support flanges extending outward from an upper portion of the pair of opposing ends walls and the pair of opposing sidewalls.

A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline includes an upstream portion of the pipeline supplying a flow of fluid material, a crossing portion of the pipeline receiving the flow of fluid material from the upstream portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline, the downstream portion, a pipeline pressure activated valve selectively capable of blocking the flow of fluid material from entering the crossing portion based upon a change in pressure within the crossing portion, and a fluid capacitor connected to the upstream portion configured to filter out a pressure spike in the upstream portion associated with the valve blocking the flow of fluid material.

Improvements in a portable vehicle fueling kiosk is disclosed. The kiosk is constructed on a pallet or a skid that allows the kiosk to be placed, located or moved to a location where the fuel dispensing is desired. A fuel tanker that would normally dispense fuel to a storage tank of a gas station is connected to one side of the kiosk. The kiosk accepts payment by nearly any form of money, credit card or token to measure, dispense and bill or invoice the user. The kiosk can have a Wi-Fi or cellular communication to communicate with a user at a distance and can monitor, use, status and remaining fuel in the tanker. If a fuel tanker has been depleted additional tankers can be connected to the kiosk, and when the kiosk is no longer needed it can be transported to another location.

This disclosure presents a deployable spill containment system and method. In one embodiment, the spill containment device forms a shallow container covering a large area. The coverage area and depth may vary. The spill containment device may have deformable walls that allow vehicles to drive over and into the protection area during deployment. Furthermore, the spill containment device may be rolled, folded, or both, for storage and transportation, such as fitting in a bed of a pickup truck. The spill containment system includes replaceable components for easy repair, exchange, and modification when needed.

The present invention provides a smart and automated system that is used for refueling of frac truck tanks during fracturing operations. The system is used to refuel the frac truck tanks which are constantly working in the high pressure and high-temperature zone for the fracturing of the wellbore to extract oil and gas. For safety, the system is equipped with explosion/fire free wiring system. The system incorporates inventive fuel valve to avoid the fuel clogging that increases the frac truck performance. The system employs artificial intelligence (AI) and cloud-based software for ease of operation and to maximize economic performance. The system is equipped with artificial intelligence and Programmable Logic Controller (PLC) software and incorporates charge pump and loop systems which maintain a predetermined pressure (in Pounds per Square Inch (PSI) unit) in each loop so as to maximize the performance and control function in the refueling system.

A method of delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. A first tank is filled with the fluid and is fluidically coupled to a second tank which may be pressurized by a compressor. The second tank is fluidically coupled to a manifold which is in turn coupled to a fluid transporting mechanism. The fluid transporting mechanism is fluidically coupled to a hydraulic connector of a fill cap which is coupled to an opening of the fluid tank. The fluid is directed from the first tank to the second tank, the manifold, the fluid transporting mechanism, the hydraulic connector and into the fluid tank through an outlet of a probe of the fill cap.

An automated machine is provided for mixing and dispensing liquid detergents remotely controlled by a control software connected to a server which updates product databases, which is executed, together with other software for dispensing and delivering liquid content and surfactant detergent with anionic and cationic tensio-active chemical compounds as the basis of its selected formulation of Genapol, sodium phenyl sulfonate and the sodium lauryl sulfonate with preservatives such as formaldehyde and bactericides such as glutaraldehyde in a mixture of concentrated detergent with water in a proportion between 30% and 40%; where said machine is manipulated with a touch screen that drives two types of injectors that send product, to make the liquid mixture, to a static mixer or to a dynamic mixer and said machine conducts said mixed liquid to a tank of finished product to be dispensed by a filling spout placed on the front of a container-shaped casing.

An improved fill cap for delivering a fluid from a fluid transporting mechanism to a fluid tank is disclosed. A connection plate is coupled to an opening of the fluid tank and a probe is disposed within the fluid tank and coupled to the connection plate at a first distal end. The fluid flows into the fluid tank through an outlet at a second distal end of the probe. A valve is disposed at the second distal end of the probe and is movable between an open position and a closed position to control fluid flow out of the probe outlet. An arm is coupled to the valve and moves the valve between the open and closed positions and a float is coupled to the arm that moves the arm depending on the level of fluid in the fluid tank.

An expanded flow rate receiver valve assembly attaches to a first fluid container and is in fluid communication with the first fluid container. The expanded flow rate receiver valve assembly includes a coupling section that selectively receives a closure valve attached to a second fluid container that selectively releases and restricts fluid contained in the second fluid container. The expanded flow rate receiver valve assembly also includes a valve chamber in fluid communication with the coupling section and located adjacent a coupling section opening. The valve chamber is in fluid communication with the first fluid container.
