The present invention is a system and method of storing various quantities of cryogenic material with lower cost than systems found in prior art. Novel feature of the system is the ability to use minimum amounts of different types of energy to maintain various quantities of cryogenic material. An additional novel feature is the use of common components and materials.

A method for generating an insulating vacuum in a container is provided. The method includes evacuating air from a space between double walls of the container for a first predetermined time period. The method also includes after the first predetermined time period, if a vacuum level within the space has not reached a first predetermined vacuum level, purging the space by supplying a gas into the space and subsequently evacuating the air from the space for a period of time equal to the first predetermined time period. The method also includes repeating the evacuating and purging until the vacuum level within the space reaches the first predetermined vacuum level. The method also includes when the vacuum level within the space reaches the first predetermined vacuum level, evacuating the air from the space for a second predetermined time period.

The subject matter described herein relates to a method for filling fluid containers, in particular fluid containers for fuel cells The method includes: providing a pressure chamber having a pressure chamber interior; positioning a fluid container within the pressure chamber interior in such a manner that a holding space of the fluid container is fluidically connected to the pressure chamber interior; evacuating the pressure chamber interior up to a target negative pressure in such a manner that, due to the fluid coupling, a negative pressure difference initially forms in the pressure chamber interior with respect to the holding space; and filling the fluid container by introducing a fluid into the holding space.

An LPG reclaim system for withdrawing and reclaiming liquefied petroleum gas (LPG) from an unspent LPG cylinder. The reclaim system has a reclaim station for reclaiming unspent LPG from LPG bottle containers, a compressor for applying a vacuum on the reclaim station and pressurizing LPG vapor from the reclaimed LPG fluid, and a receiving tanlc for receiving a stream of pressurized liquid LPG. The reclaim system has a pair of shell-and-tube heat exchangers include cold-side tubes and a hot side shell. The reclaimed LPG fluid is passed through the cold-side tubes, while the pressurizing LPG vapor is passed through the hot-side shell of the heat exchanger. The heat applied to the cold-side reclaimed LPG fluid promotes evaporation of the LPG fluid to LPG vapor for pressurizing, and the cooling applied to the hot-side pressurized LPG vapor promotes condensation of the LPG vapor to LPG liquid for the refill containers.

An installation for supplying gas provided with an insulating chamber including a rear wall and two side wall as well as a door that pivots about a vertical axis in order to allow opening and closing of the chamber, the installation including two multifunctional blocks that house a fluid circuit and are attached to the rear wall inside the chamber.

A fluid supply package comprising a pressure-regulated fluid storage and dispensing vessel, a valve head adapted for dispensing of fluid from the vessel, and an anti-pressure spike assembly adapted to combat pressure spiking in flow of fluid at inception of fluid dispensing.

A service device for a multi-component insulating gas for use during maintenance of electrical switchgear systems comprising a compressor with a downstream condenser, a storage container, the service device is connected to a system space, and the compressor compresses the insulating gas during removal from the system space, all components of the insulating gas remain in the compressor in a gaseous state, the condenser is controlled by a controller so a condensation of the insulating gas occurs first in the storage container, a storage heating device is provided for the storage container, during filling of the system space the storage heating device heats the insulating gas to a temperature above the critical temperature of the insulating gas, wherein, a line heating device is provided which at least partially heats the pipeline between the storage container and the system space and/or heats elements in the pipeline.

A method is provided for producing a tank, in particular a motor vehicle tank, for storing a fuel in a low-temperature state. The tank has an inner tank receiving the fuel, an outer skin surrounding the inner tank and an insulating layer arranged between the inner tank and the outer skin. The method i) introduces fuel into the inner tank, a temperature of 30 C. to 120 C., preferably of 70 C. to 85 C., being obtained by the fuel in the inner tank, and ii) generates negative pressure in an insulating layer arranged between the inner tank and the outer skin.

A system for both housing hydrocarbons in both liquid and gaseous forms has a body configured to withstand both storage related internal pressures as well as processing related vacuum pressures. A method includes receiving hydrocarbons into a body configured to withstand both storage related internal pressures as well as processing related vacuum pressures.
