Method of gas analysis of component mixture

RU patent № 2206081

The invention relates to chemical industry and can be used, e.g., in the analysis of mixture composition after disintegration of liquid ammonia in a confined space. In implementation of the invention the method involves freezing out a component mixture, which is in the chamber, down to solid phase of one component which was in the vaporous-liquid state prior to freeze-out. A part of non-condensable gases is withdrawn into the second chamber which is preliminarily evacuated and chilled down to the temperature of freeze-out, then it is heated and the pressure of non-condensable gases is measured. The solid component, which is in the first chamber, is evacuated, heated and transferred to the evacuated vessel, whose volume provides transition of this component to the gaseous phase, after that the pressure of the gas obtained is measured. Then, using the equation of ideal gas state and the Boyle-Mariotte law, mass composition of mixture components is determined. Expansion of functional capabilities of the method is reached.
