Vapor-Liquid Equilibrium for the Mixture Methane (CH4) + Ethane (C2H6) over the Temperature Range (126.01 to 140.01) K

摘要

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 (MHVl) + 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.
