Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with a multi-function nozzle assembly including an exhaust nozzle corresponding to a vehicle exhaust port and a fuel nozzle for supplying fuel to a vehicle fuel tank. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. An exhaust conduit may be configured to transport captured exhaust therethrough from the exhaust nozzle to an exhaust holding tank connected to and in fluid communication with the exhaust conduit.

The invention relates to a tank for storing a cryogenic mixture of liquid and gas, comprising a first casing, a draw-off pipe for drawing off fluid, which has an upstream end connected to said first casing, a filling circuit comprising a first filling pipe with an upstream end to be connected to a fluid source and a downstream end connected to the lower portion of the first casing, said filling circuit comprising a second filling pipe connected to the fluid source and a downstream end connected to the upper portion of the first casing, wherein the upstream ends of said first and second filling pipes are designed to be connected to the same fluid source simultaneously, and a distribution valve assembly which is configured to allow distribution of the fluid in said filling pipes, wherein the tank comprises a sensor assembly which measures the pressure in the first casing, said distribution valve assembly being configured to automatically adjust the pressure in the first casing, during filling, to a predetermined pressure setpoint (Pc) by means of the automatic distribution of the flow rate of fluid from the source in the filling pipes, depending on the pressure setpoint (Pc) and the pressure measured by the sensor assembly.

The present invention relates to a gas treatment system and a ship including the same. The gas treatment system treats liquefied gas as heavier hydrocarbons or ammonia. The gas treatment system includes: a fuel tank storing liquefied gas as a fuel to be supplied to a propulsion engine of a ship; a liquefied gas supply line supplying the liquefied gas of the fuel tank in a liquid phase to the propulsion engine, the liquefied gas supply line having a high pressure pump provided thereon; a reliquefaction apparatus liquefying boil-off gas generated in a cargo tank storing liquefied gas; and a liquefied gas collection line collecting the liquid liquefied gas discharged from the propulsion engine upstream of the high pressure pump. The reliquefaction apparatus transfers the liquefied boil-off gas to the fuel tank, thereby allowing the liquefied boil-off gas to be supplied to the propulsion engine by the high pressure pump.

The present invention provides a leak-proof fluid dispensing system with a pressure sensor and an adjustable dispensing regulator, comprising: a gas cylinder and a pressure dispensing control valve. The dispensing control valve is formed outside the bottle body opening and has an internal channel that communicates with an inlet port, an outlet port, a bottle port, and the joint portion. The internal of the dispensing body includes an inlet valve, an outlet valve, a pressure dispensing regulator, a filter, and a pressure sensor. The pressure at the outlet end of pressure dispensing regulator is lower than or equal to a preset opening pressure value, the fluid is allowed to flow out. With the implementation of the present invention, it may prevent accidental leakage of fluid in the gas cylinder and dynamically monitor the flow gas capacity in the gas cylinder.

A process for the reduction of flaring/venting gases during completions operations on an oil/gas well, said process comprising providing a well in need of completion; providing a system to capture oil and gas generated by the well; the system including a primary separator to separate an incoming well stream into a plurality of streams wherein a first stream is sent to a pipeline and a second stream is sent for further processing. The process further includes flowing and collecting a third stream of gas in a gas pressure vessel; compressing the collected gas in the vessel until parameters of compressed gas are compressed to provide a constant feed to the pipeline; and transferring the compressed gas to the gas pipeline wherein the process reduces the amount of gas flared and/or vented during operation by over 80%.

Disclosed is a method for automatically replacing high-pressure gas barrels, in which when loading a high-pressure gas barrel is loaded on the lift of a cabinet so as to supply gas to the wafer production line in the semiconductor fabrication FAB process facility, at the time point of replacement of the high-pressure gas barrel, a used high-pressure gas barrel is separated from a connector holder and then a new high-pressure gas barrel is connected to the connector holder.
