A safety vacuum supply gas cylinder includes a cylinder body, a pipeline structure, first and second check valves (respectively having first and second check valve opening pressures P.sub.c1, P.sub.c2, wherein P.sub.c1 is greater than an atmospheric pressure P.sub.0). The cylinder body has an opening and an internal space configured to store a gas, wherein the gas forms an internal pressure P.sub.2 smaller than P.sub.0. The pipeline structure, communicated with the opening, has first and second pipelines where the first and second check valves are respectively arranged. An external filling gas enters the cylinder body when a pressure of the external filling gas is greater than P.sub.c1 and P.sub.2. The gas flows out when P.sub.2 is greater than P.sub.c2 and an external environmental pressure.

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.

A gas cylinder transfer apparatus and a gas cylinder logistics system including the same are disclosed. The gas cylinder transfer apparatus includes a transfer vehicle for transferring a gas cylinder and a transfer robot disposed on the transfer vehicle. The transfer robot includes a robot hand for supporting a lower surface portion of the gas cylinder and a hand drive unit for moving the robot hand in horizontal and vertical directions.

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).

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.

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.
