This invention relates to a novel method and system for dispensing CO2 vapor without over pressurization from a system having multiple containers. The system includes one or more liquid containers and one or more vapor containers. The system is designed to operate in a specific manner whereby a restricted amount of CO2 liquid is permitted into the vapor container through a restrictive pathway that is created and maintained by a shuttle valve during the filling operation so that equalization of container pressures is achieved, thereby allowing shuttle valve to reseat when filling has stopped. During use, a pressure differential device is designed to specifically isolate the vapor container from the liquid container so as to preferentially deplete liquid CO2 from the vapor container and avoid over pressurization of the system until the vapor container becomes liquid dry. The system can be operated so that at least 50% of the CO2 vapor product is dispensed from the vapor container.

A cryogenic tank assembly includes a cryogenic tank having an internal volume that is configured to contain liquefied natural gas (LNG). The cryogenic tank includes an inlet and an outlet that are each fluidly connected to the internal volume. The assembly includes a recirculation conduit coupled in fluid communication between the inlet and the outlet. The recirculation conduit extends along a path between the inlet and outlet external to the internal volume of the cryogenic tank such that the path is configured to be exposed to an ambient environment of the cryogenic tank. The recirculation conduit is configured to: receive a flow of LNG from the internal volume through the outlet; transfer heat from the ambient environment to the LNG flow to change the LNG flow to a flow of natural gas; and inject the natural gas flow into the internal volume of the cryogenic tank through the inlet.

The invention discloses a new embodiment concept and components for drying articles in an energy-efficient and effective way. The embodiment has a stationary drum accommodating a grid with several underneath nozzles at the bottom for blowing compressed hot air into articles and moving them within the space. A magnetron generates microwaves inside the drum for evaporating articles' moisture. A reciprocating compressor vacuums out the hot vapor and compresses it again in a high-pressure three-layer multifunctional tank after passing through a set of moisture separators to be reused by the nozzles in a closed cycle. Several low-maintenance and durable Membrane Dryers are used in parallel as a moisture separator unit before the compressor. Condensed and separated liquid is used in a heat exchanger to warm the makeup air needed for membranes. Nozzles' on/off states, the magnetron and compressor are controlled by a closed-loop digital controller for achieving an optimized drying process.

Methods and systems for reducing a pressure of compressed natural gas and for delivering natural gas are disclosed. A regulator comprising a vortex tube may be used to reduce the pressure of compressed natural gas while a temperature thereof is also reduced. The temperature reduction associated with a pressure drop in the compressed natural gas is achieved by throttling the gas at constant enthalpy from 3,000 psig to 150 psig through the regulator. At least one heat exchanger may be utilized to increase the temperature of the compressed natural gas to a temperature suitable for injection delivery. A pressure-reducing regulator may be used to further reduce a pressure of the gas to about 45 psig for delivery to an end-user.

A high pressure media storage vessel including a wall made of at least one layer with barrier and piezoelectric properties.

An adapter for a pressure vessel comprising a first connection for coupling to a device for filling and/or withdrawing a fluid, in particular a gas, a second connection for a fluid-tight connection with the pressure vessel, and a line section. The line section extends along a longitudinal axis and connects the first connection with the second connection and thereby a gas-permeable connection between the first connection and the second connection exists or can be established via an interior space. At least one sensing unit s set up to detect at least one physical quantity and to convert it into at least one measurement signal. An evaluation unit is connected to the sensing unit and the evaluation unit is set up to process and/or evaluate the measurement signal and to make it available as an output signal via the communication interface.

The multi-stage home refueling appliance includes a first compressing stage having a first stage inlet fluidly coupled to the supply of natural gas and a first stage outlet, a second compressing stage having a second stage inlet fluidly coupled to the first stage outlet and a second stage outlet and a vehicle refueling dispenser fluidly coupled to the second stage outlet and configured to be selectively fluidly coupled to a storage tank of a vehicle.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.
