ENTHALPY-CONCENTRATION GRAPHS FOR A NITROGEN-METHANE MIXTURE

Kazimierz Brodowicz, Stefan Ermich

Abstract


Thermodynamic graphs for a methane-nitrogen mixture within the region of gas phase, of a two-phase mixture, and of a liquid phase, have been presented herein. The enthalpy of mixing has been taken into the consideration while plotting the graphs.

The enthalpy-concentration system of coordinates has been adopted. The scope of intensive parameters included: molar percentage of nitrogen content in the mixture 0÷100%, at the temperature of (70) 100÷200 K, pressure assumed as a discrete variable parameter equals respectively 0,1014, 1,0342, 2,0684, 3,1027, 4,1369, 4,8264 MN/(sq*m) in succession.
