An automatic cover-opening and connector-replacing device for chemical container is disclosed. The device solves the problems of toxic substance leakage and even industrial safety accidents like gas explosions due to aging equipment during the maintenance by operating personnel in high-risk operation areas. The automatic cover-opening and connector-replacing device for chemical container mainly includes a machine, a lifting device provided inside the machine, a cover-opening device connected with the lifting device and a liquid-pumping device connected with the lifting device. The cover-opening device is provided for assembling and disassembling the internal cover of a chemical container and the liquid-pumping device is provided for pumping the content of the chemical container where the lifting device is provided for adjusting the distance between the cover-opening device, liquid-pumping device and chemical container.

Devices, methods, and systems are provided for detection of various leaks within fuel dispensers, such as through visualization within a fuel dispenser. An exemplary fuel dispenser can include a housing having fuel dispensing components disposed therein, a control system in the housing for controlling the dispensing of fuel, and a leak detection assembly for detecting a fluid leak within the housing, and for visually confirming the presence of a leak using an imaging device.

A fuel dispenser sump conduit support. The fuel dispenser sump conduit support includes a conduit attachment structure, a bracket, and a sump interface. The bracket is connected to the conduit attachment structure at a bracket interface. The sump interface is disposed on the bracket distally from the from the bracket interface. The sump interface includes a surface connectable to a fuel dispenser sump.

A volatile liquid refueling apparatus, which includes a probe, and a receiver including a dual locking mechanism whereby said apparatus can be locked in either an open position or a closed position, and a safety lock which disables or enables access to the dual locking mechanism when manually.

A hydrocarbon dispensation line pressure sensor adapted to work without requirement of a separate closed valve. The system closes the dispensation line upstream via an isolation valve. The pressure can be sensed from the dispensation line through the valve to provide dispensation line pressure. A channel in fluid communication with the dispensation line may be provided to allow pressure measurement apart from the main dispensation line. Further, a method for measuring the pressure drop profile of a dispensation line and various methods to determine the pressure loss due to leaks in dispensation line.

A dispensing unit having a circulation system for circulating a fluid in the dispensing unit is provided. The circulation system comprises, a circulation circuit, and a mechanism configured to circulate the fluid in the circulation circuit. By circulating the fluid, the fluid is counteracted from crystallizing. A method for circulating a fluid in a dispensing unit is also provided.

The present invention relates to a coupling for a connecting a LNG nozzles to a LNG vehicle tank receptacle and their connection apparatus to a LNG vehicle tank for fueling. The invention comprises a double connection system to provides additional safety to a LNG Nozzle Locking Mechanism for being locked into a LNG receptacle on a vehicle tank, by combining two different locking mechanisms: one the so-called collet type locking mechanism with the locking handles, and two the valved receptacle and valved nozzle approach with the rotating handle.

The spilled fuel collection system is configured for use with the fuel vent of a vessel. The fuel vent is designed to release gas and fuel during an event selected from the group consisting of: a) a build-up of gas pressure within the fuel tank; and, b) overfilling the fuel tank with fuel. The spilled fuel collection system is an accessory that captures fuel and fuel vapors that escape through the fuel vent of a vessel during the fueling process. The spilled fuel collection system comprises a transportable fuel container, a hose, and a quick connect fitting. The transportable fuel container captures the fuel and vapor that escape through the fuel vent. The hose transports the escaped fuel and vapor from the fuel vent into the transportable fuel container. The quick connect fitting secures the hose to the fuel vent.

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.

A product delivery system includes a product transport vehicle having at least a plurality of tank compartments, internal valves, control valves, fluid property sensors, temperature sensors, overfill sensors, pressure sensors, a system controller, and a memory module. The product delivery system may be operable to communicatively connect with the loading system at a loading station, a fleet management system, or a cloud system to obtain information, such as the amount of liquid product to be loaded into a tank compartment. The product delivery system may be operable to compare the volumes of the tank compartments with the amounts of liquid product to be loaded at a loading station and maintain the internal valve or control valve in a locked state or transition the internal valve or control valve to an unlocked state based on the comparison. Other comparisons based on liquid type or distribution tank volume can also be made.
