PHASE EQUILIBRIA OF DRY AIR AT LOW PRESSURE.

Abstract

Phase equilibria for an oxygen-nitrogen mixture equivalent to dry air (21% oxygen and 79% nitrogen) were computed for the temperature range 65K to 35.61K. Dew-point and bubble-point pressures for the mixture were evaluated. Experimental measurements were made of the bubble-point vapor pressure of a dry air mixture in the temperature range 34K to 64K. Samples of the bubble-point equilibrium vapor of a dry air mixture were obtained in the temperature range 47K to 64K. These were analyzed to determine the mole composition of the vapor in terms of oxygen and nitrogen content. (Author)
