A method of recovering energy produced by the change of phase of dry ice using a device having an enclosure (2) containing dry ice at an infra-atmospheric pressure and at a solidification temperature corresponding to the infra-atmospheric pressure; and a primary energy recovery circuit (3), in which a heat transfer fluid circulates, passing through the enclosure. The method involves passage of the heat transfer fluid into the primary circuit (3), this step causing the heating of the dry ice and its change of phase into CO2 and the cooling of the heat transfer fluid; extraction of the CO2 contained in the enclosure (2); and substantially continuous lowering of the pressure of the enclosure (2) to an infra-atmospheric pressure.

A set (10) for dispensing liquefied gas from a vessel (100) comprises a supporting structure (1), a pump (2) and a conditioning system (4). The supporting structure is designed for maintaining both the pump and the conditioning system inside the vessel when the set is in operation condition for dispensing a flow of liquefied gas. The set allows easy handling, simple fitting to the vessel and easy removal from the vessel because a main part of said set can be handled as a one-block element.

The invention relates to a transport container (1) for helium (He), comprising an inner container (6) for receiving the helium (He); a coolant container (14) for receiving a cryogenic fluid (N2); an outer container (2) in which the inner container (6) and the coolant container (14) are received; a thermal shield (21) in which the inner container (6) is received and which can be actively cooled using the cryogenic fluid (N2), said thermal shield (21) having at least one cooling line (26) which is fluidically connected to the coolant container (14) and in which the cryogenic fluid (N2) can be received in order to actively cool the thermal shield (21); and at least one return line (34, 35), by means of which the at least one cooling line (26) is fluidically connected to the coolant container (14) in order to return the cryogenic fluid (N2) back to the coolant container (14).

A sterilized-liquefied gas apparatus of the invention includes: a liquefied gas reservoir; a source-gas supplier that supplies a source gas to the liquefied gas reservoir; a cooler that cools down an inside of the liquefied gas reservoir and thereby liquefies the source gas; a supply pipe that connects the source gas supplier and the liquefied gas reservoir; a sterilization filter provided in the supply pipe; a sterilizer that sterilizes, by a sterilizing gas, a sterilization region that is located further downstream than the sterilization filter; and a sterilizing-gas remover that removes the sterilizing gas after sterilization.

The present invention is embodied in a carbon dioxide compression and delivery device that uses a plurality of reversible thermoelectric devices and to a method to operate such carbon dioxide compression and delivery device.

A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel.
