In one preferred embodiment, the present invention splits off some of the excess capacity gas flow from a gas concentrator (11) which is then stored (14) via liquefaction. The stored gas can then be used as a portable supply. A portion of the oxygen gas flow generated by the oxygen concentrator is channeled to a condenser (13) which receives and liquefies the oxygen gas using cryocooler (12). A storage dewar (14) is used for storing the oxygen liquefied by the condenser. Liquid is then selectively transferred to a smaller portable dewar (23). A controller can be used for monitoring the parameters of liquefaction, including oxygen concentration, the amount of liquid oxygen in the dewar, and for controlling the parameters of liquid oxygen generation and transfer.

En la presente invención es la mejora de un dispositivo para la separación gas, basado en separadores flash. La función principal es lograr una dispersión homogénea sobre el intercambiador de calor con los separadores flash con el fin de lograr un mejor intercambio de calor de las gotas del condesnado del gas y las paredes del mismo intercambiador. Con la ayuda del enfriador criogénico el gas no condensado, en condensado obteniendo así un volumen del líquido. El cual posteriormente será tratado en una torre de destilación para la separación de los componentes.
摘要:
A cryogenic gas is liquefied using a refrigeration system [101] thermally coupled at an evaporator [125] to a cold end of a gas supply system [103] within a dewar [116]. The refrigerator has a minimum temperature at an evaporator [125] above the boiling point of the gas at atmospheric pressure but below the boiling point of the gas at a high pressure. Thus, the gas is compressed [128] to high pressure so it condenses when cooled by the evaporator [125]. As it expands at a flow restrictor [148], a portion evaporates and cools a fraction to the temperature of the boiling point of the gas at atmospheric pressure, producing liquefied gas. Opening a purge valve [142] sends warm gas upward through heat exchange section [146] and out through a three-way valve [138] for defrosting. To reduce clogging, the gas supply valve [138] is controlled by a gas purity sensor [158].
摘要:
A method and an arrangement (100) for phase conversion. The arrangement has a space (30) including a working gas (33) and is arranged to include a generated standing sound wave, whereby said sound wave is generated such that the sum of added and consumed wave energy is greater than or equal to zero. Furthermore, the arrangement has a valve mechanism (10, 20) for provision and outflow of a quantity of a working gas or composition, consisting of at least one substance, in the space (30) and is arranged to work synchronously with the generated sound wave. The generated sound wave exposes the working gas or composition to pressure and temperature changes, whereby a gas compression creates an elevated temperature and a gas decompression creates a reduced temperature; and whereby a phase conversion, caused by the pressure and temperature changes, is obtained.
