An apparatus, system, and method for temporary fluid commodity transfer stations. A fluid commodity transfer structure can include a base member, a casing, and a fluid commodity transfer system. The fluid commodity transfer system can be configured to dispense a commodity for transloading from opposite sides of the fluid commodity transfer structure. A modular fueling station system can include one or more receptacles operably coupled to a fluid commodity transfer structure to allow a fluid commodity transfer system to utilize each receptacle as a fuel reservoir. The fluid commodity transfer structure can be loaded onto an intermodal transport vehicle, unloaded at a location, deposited at the location, and be operably coupled with one or more receptacles and/or other fluid commodity transfer structures to provide fueling infrastructure for fleet vehicles or allow for the commercial transfer of fluid from one receptable to another as a mobile fluid transfer system.

The filling station (1) for means of transport (4) comprises: a supply (2) of a methane pipeline transporting gaseous methane; a liquefaction assembly (A) connected in a fluid-operated manner to the supply (2) and adapted to liquefy the gaseous methane conveyed by the methane pipeline to obtain liquid methane; at least one dispenser (3) of the liquid methane, which is connected in a fluid-operated manner to the liquefaction assembly (A) and is connectable in a removable manner to a means of transport (4) to supply the means of transport (4) with the liquid methane.

A method of determining an optimum value of at least one first parameter of execution of a process for cooling an internal space of a tank, including testing a plurality of different values of the first parameter, each phase of testing one of the values of the first parameter including cooling the internal space of the tank, the cooling power P.sub.f or the setpoint final temperature T.sub.c being representative of the tested value of the first parameter. The steps include loading liquefied gas into the internal space of the tank after cooling, measuring a variable P1 representative of the pressure inside the thermal insulation barrier and comparing it to at least one particular threshold, and detecting a fault if the variable P1 crosses the at least one particular threshold, and choosing, among the plurality of values tested, the optimum value of the first parameter during the corresponding test phase.

In a gas supply system of one embodiment, if first detection information of a high-pressure sensor exceeds a first threshold value, a gas control ECU causes a pressure adjustment range to overlap a second error range of second detection information of a mid-pressure sensor, the second error range being defined with a second threshold value as a reference point. If the first detection information is less than or equal to the first threshold value, the gas control ECU offsets the pressure adjustment range relative to the second error range defined with the second threshold value as the reference point.

Some embodiments are directed to a module for depressurisation and storage of a portion of a gas layer coming from at least one cryogenic tank. Some other embodiments are directed to a system using such a module.

A method for automatically dispensing and vending carbon dioxide (CO2) snow block is disclosed. The automatic dispensing system contains multiple containers of different volumes. A user can input the volume of CO2 snow block into a controller, such as a programmable logic controller (PLC). The controller uses the inputted volume and process information to determine which container to utilize for the automated filling process. The controller can configure the selected container into a filling orientation into which liquid CO2 can flow to generate CO2 snow block. Upon detection of the completion of the fill, the container is configured into a dispensing orientation from which the CO2 snow block is released into an access region from which the user can retrieve the CO2 snow block. The control methodology may also be used to auto charge a single container located within a charging station as disclosed herein.

A fluid transfer apparatus transfers fluid from a first bulk storage vessel at a gas pressure equal to or greater than a first gas pressure. The fluid transfers to a first or second supply vessel; each having a gas pressure equal to or less than a second pressure. The second pressure less than the first pressure. The fluid transfer continues until the fluid in the first or second supply vessel reaches a predetermined weight inside the first or second supply vessel. The fluid in the filled first or second supply vessel, at the predetermined weight, under a pressure equal to or less than the second pressure; and the fluid in a liquefied and gas state. The apparatus heats the fluid in the first or second supply vessel, filled to the predetermined weight, to bring the fluid in the first or second supply vessel to a third gas pressure. The third gas pressure higher than the first gas pressure and the second gas pressure. The fluid in the first or second supply vessel having the third gas pressure can include fluid in the liquefied gas state and gas state or super critical state.
