Abstract
Method and apparatus for separating gases having different partial pressures at a given temperature includes introducing a multi-component gas mixture into a chamber, reducing the temperature therein to solidify and liquefy all components. At least one component remains liquid which is evaporated, thereby separating such component from the solidified components which may then be liquefied and recovered. The process is especially useful in recovering radioactive krypton and xenon from the off gas streams of nuclear processes such as nuclear fuel reprocessing.
