One of the important activities in chemical engineering is designing and simulating different processes in order to optimize the unit economically and operationally. Thermodynamic and transmissivity properties of fluid in this process are required to be available carefully. In this article, thermodynamic equations operation in PR, SRK, LKP, UNIQUAC in expecting thermodynamic properties and phase operation of binary system of Dinitrogen monoxide and Propane have been studied in order to select the best equations of state (EOS) for simulation. According to the results it is obvious that equation of state PR in expecting Bubble point ( P ) have mean absolute error equals to 4.98 and mean absolute error in specifying the value of mole fraction of Dinitrogen monoxide in steam phase ( Y1 ) equals to 0.002338 . It is the minimum error among other models. As a result, alternatively PR, UNIQUAC equations are the best and the weakest models for expecting phase operation and simulating binary system of Dinitrogen monoxide and propane (among considered equations).
