In this work we present experimental results of P, T, x, y, for the vapor-liquid equilibrium of the ternary system: nitrogen in an equimolar hexane + decane mixture at 258, 273, and 298 K in the range 1.5-20 MPa. The solubility of nitrogen in the liquid mixture of hexane+decane is increased when the pressure is increased; however, a considerable change in the solubility values is not observed as a function of temperature in the range studied. We have correlated the experimental results using the Peng-Robinson equation of state. The standard deviation of the fit shows that the data are well correlated (within the experimental error) in the ranges of pressure and temperature studied. (C) 2004 Elsevier B.V. All rights reserved.
