The fugacity coefficients of hydrogen in binary mixtures with ethane were measured using a physical equilibrium technique. This technique involves the use of an experimental chamber which is divided into two regions by a semipermeable membrane through which hydrogen, but not ethane, can penetrate. Measurement of the gas pressures inside and outside of the membrane allows a direct measurement of the hydrogen component fugacity coefficient at a given temperature and binary-mixture mole fraction. In this paper, results are reported at 101, 116, 141, 151, 160, and 190/sup 0/C. In each case the total pressure of the mixture was maintained at 3.41 MPa. The qualitative features of the measurements are discussed and comparisons are made with predictions obtained from the Redlich-Kwong, Peng-Robinson, and extended corresponding-states models.
