The method for producing a filled container of the present invention includes: providing a metal storage container, at least an inner surface of which is formed of a manganese steel and in which the inner surface has a surface roughness R.sub.max of 10 m or less; performing fluorination by bringing the inner surface of the storage container into contact with a gas containing at least one first fluorine-containing gas selected from the group consisting of ClF.sub.3, IF.sub.7, BrF.sub.5, F.sub.2, and WF.sub.6 at 50 C. or lower; purging the inside of the storage container with an inert gas; and filling the inside of the storage container with at least one second fluorine-containing gas selected from the group consisting of ClF.sub.3, IF.sub.7, BrF.sub.5, F.sub.2, and WF.sub.6.

A novel and improved inventive valve with a regulating function is provided that is capable of filling to higher fill pressures than previously attainable with conventional C-10 on-off valves. The valve contains a single flow passageway by which gas dispenses and enters the valve. A fill adapter is specially configured to engage the valve to allow filling at the higher pressures along the single flow passageway. The structure of the valve allows greater utilization of cylinder capacity; simplifies filling and dispensing with the single flow passageway; and allows for regulating gas pressure during delivery without increasing the overall size of the cylinder package.

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.

To provide a hydrogen sulfide mixture hardly corroding metals. The hydrogen sulfide mixture contains hydrogen sulfide and water. The hydrogen sulfide mixture is filled into a filling container so that at least one part of the hydrogen sulfide mixture is liquid and the moisture concentration of a gaseous phase is 0.001 mol ppm or more and less than 75 mol ppm.

Embodiments of systems and methods for transporting liquefied gas 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 an outer surface, an outer compartment within the outer shell configured to store liquefied gas, a bladder positioned within the outer compartment configured to store CO.sub.2, and insulation positioned between the outer shell and the outer compartment to provide temperature regulation for the liquefied gas when positioned in the outer compartment and CO.sub.2 in the bladder.

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.

A material at least partly coated with a passive film of fluoride formed by contact with a gas containing ClF.

A method supply equipment for supplying a fluorine gas-containing gas which includes a sealing step of introducing a second fluorine gas-containing gas having a fluorine gas concentration in a range of ?10% of that of a first fluorine gas-containing gas into a portion between a container valve (3) and a pressure regulator (7) of a pipe (4) such that a pressure is lower than the gas pressure in a filled container (2). After the sealing step, a buffer tank (9) is brought into an opened state, and then the first fluorine gas-containing gas is supplied from the filled container (2) to the portion between the container valve (3) and the pressure regulator (7) of the pipe (4). Thereafter, the pressure regulator (7) is brought into an opened state, and then the first fluorine gas-containing gas is supplied to consumption equipment (20) while regulating a pressure by the pressure regulator (7).
