Phase Equilibrium in an Octadecane–Propane/n-Butane System

Results are presented from an experimental study of the phase equilibrium ( PTxy dependence) of an n- octadecane–propane/ n -butane system for three isotherms (403.15, 423.15, 443.15 K) in the 0.89–7.24 MPa range of pressures using a high-pressure optical cell. The PTxy data are used to determine cr...

Description
Summary:Results are presented from an experimental study of the phase equilibrium ( PTxy dependence) of an n- octadecane–propane/ n -butane system for three isotherms (403.15, 423.15, 443.15 K) in the 0.89–7.24 MPa range of pressures using a high-pressure optical cell. The PTxy data are used to determine critical parameters of a mixture with identical concentrations of the two phases ( x = y at fixed P and T ).
