Abstract

In modern technologies or manufacturing or clearing of low-temperature gases are realized the processes with phase transitions liquid-gas. Development of the reliable ways based on use of uniform equations of state is necessary for their description. Evolution of fugacity-composition-gross structure diagrams is investigated for cases of solubility of gases in liquids. For calculation of diagrams the three-parametrical cubic equation of state is chosen. Areas of binary system unstable conditions are analysed and new qualitative kinds of dependences of components volatility from structure of binary system are revealed. Use of features of volatility-composition diagrams allows to find initial approximation the decision of tasks of solubility of gases in liquids.
