摘要

Equipment to increase safety in gas liquefaction or gas or oxygen in the gas storage lu00ecquido or gas of oxygen lu00ecquido and reduction in the rate of leakage of oxygen lu00ecquido in the event of inclination.Apparatus and methods for improving safety and efficiency and reduce the production cost of gas, liquid, such as liquid oxygen, with a device for liquefaction of use on a small scale, according to various methods of this invention.In one form, may be added as a barrier to liquid oxygen (118) at the interface between a crioarrefecedor (102) and a Dewar (120) to control a speed of leakage of liquid oxygen, after an inclination of the dewar (120).A pot of boiling (560) in fluid communication with the dewar (120) allows the gas in the expansion from a Dewar (120) inclined exhaust, while allowing the liquid in the vessel based surely boiling (560).A temperature sensor (299, 297), in the vicinity of a heat sink or cold finger of the crioarrefecedor (102), is operable to disconnect a circuit of electric power of the crioarrefecedor or cooling fan, when the temperature exceeds a temperature predeter sensoriada Mined. The purity of oxygen in a flow of gas supply can be sensoriada and / or displayed.
