    Abstract

    In this communication, experimental measurements and thermodynamic modeling of solubilities of methane and a hydrocarbon gas mixture (94% methane + 4% ethane + 2% n-butane) in water at low temperature conditions are reported. Methane solubility measurements have been conducted at a temperature range of 275.11-313.11 K and pressures up to 18 MPa. The solubility of the individual components in the gas mixture was measured from 278.14 to 313.12 K and pressures up to 14.407 MPa. A static-analytic apparatus, taking advantage of a pneumatic capillary sampler is used for fluid sampling. The Valderrama modification of the Patel-Teja equation of state combining with non-density dependent mixing rules were used for modeling gas solubilities in water. The data generated in this work are compared with the literature data and the predictions of the thermodynamic model, demonstrating the reliability of the techniques used in this work. © 2004 Elsevier B.V.
