ABSTRACT
A single-cycle apparatus was used to measure vapor liquid equilibrium (VLE) data for the binary system (CH4 + C2H6) over low temperatures of (126.01 to 140.01) K and pressures up to 0.64 MPa. The Peng Robinson (PR) + modified Huron Vidal mixing rule (MHV1) + Wilson model was used to correlate the experimental data for the binary system (CH4 + C2H6), and the interactive parameters of the Wilson model were given. The model gave satisfactory results over the range of experimental temperatures and pressure.
