Abstract
Abstract Methods and apparatus for gasification of liquid nitrogen and other cryogenic liquids are provided. The apparatus includes a gasification unit capable of refrigerating at least one cryoelectronics energy converter and utilizing the heat generated thereby to gasify a cryogenic fluid. Refrigeration is provided by the cryogenic fluid in the gasification unit. The gasification unit is preferably capable of gasifying at least 1 liter/hour of cryogenic fluid. The gasification unit can be coupled to a chemical processing unit such that gasified cryogenic fluid produced in the gasification unit can be introduced into the chemical processing unit for use therein. A secondary heat recovery unit can be provided upstream of the chemical processing unit to separate entrained liquid particles from the gasified cryogenic fluid produced by the gasification unit. Cryogenic fluid can be supplied to the gasification unit from an air liquefaction plant, a storage tank, a truck or the like. The gasification unit can be used to gasify nitrogen, liquefied natural gas, carbon dioxide, oxygen, hydrogen, argon, neon or other cryogenic fluids.
