摘要
权利要求	1. IN THE LOW TEMPERATURE PHYSICAL SEPARATION OF ONE COMPONENT FROM A MIXTURE OF GASES, WHICH MIXTURE IS CHARACTERIZED BY A PHASE DIAGRAM HVING A GAS-SOLID REGION, THE SOLID BEING PROVIDED BY THE COMPONENT DESIRED TO BE SEPARATED, IN WHICH GAS-SOLID REGION THE TEMPERATUREPRESSURE RELATIONSHIP, AT A CONSTANT COMPOSITION OF GAS PHASE, DEFINES A GAS-SOLID LINE HAVING A POSITIVE SLOPE OVER AT LEAST A PORTION OF ITS LENGTH AND A NEGATIVE SLOPE OVER ANOTHER PORTION ABOVE THE POSITIVE SLOPE, AND ALSO CHARACTERIZED BY THE EXISTENCE OF A SUBREGION WITHIN SAID GASSOLID REGION WITHIN WHICH SUBREGION SAID LINE, AT THE CONSTANT COMPOSITION OF THE GAS PHASE, HAS ONLY THE POSITIVE SLOPE, WHERE THE TEMPERATURE AND PRESSURE OF SAID GAS MIXTURE ARE CONTROLLED TO BRING SAID GAS MIXTURE WITHIN SAID GAS-SOLID REGION AND THE GAS PHASE IS SEPARATED FROM THE SOLID PHASE, THE SAID POSITIVE AND NEGATIVE SLOPES OF
