Abstract

The present invention relates to a system and method for improving the liquefaction rate in cryocooler-based cryogen gas liquefiers. The present invention relates to a cryogen-gas liquefaction system(1) and method comprising: a storage container (2) comprising a liquid storage portion (3) and a neck portion (4) with a liquefaction region (8) above said bath (7); a coldhead (9) arranged at the neck portion (4) comprising one or more refrigeration stages (10, 11); a gas intake module (12) containing an amount of gas-phase cryogen for its introduction into the storage container (2); and a pressure control mechanism (13) for controlling the cryogen gas pressure within the liquefaction region (8) of the storage container (2).

Description

technical field [0001] The present invention relates generally to systems and methods for liquefying gases, and more particularly to such systems and methods adapted to obtain increased liquefaction and performance efficiencies. The main field of application of the present invention is helium liquefaction technology, eg small scale liquefiers with liquefaction rates <100 liters / day, based on closed cycle refrigerators. Background technique [0002] Helium is a rare element on Earth and its various scientific and industrial applications continue to drive growing demand. For example, common uses of gas-phase helium include welding, lifting (balloons), and semiconductor or fiber optic manufacturing. In the liquid phase, common uses include refrigeration in certain medical and scientific equipment, cleaning fuel tanks, and basic research in solid-state physics, magnetism, and various other research topics. Due to its widespread use and limited availability of helium, it is ...
