Abstract

The volumetric behavior of the methane - n butane - decane system was experimentally investigated at seven temperatures in the interval 100° to 4600°F. at pressures up to 10,000 pounds per square inch absolute. The apparatus and methods employed in the investigation are discussed.

The experimental data, which were taken at random pressures and arbitrarily chosen compositions of the system, were graphically interpolated to a uniform series of pressures and a systematic distribution of compositions. The results are presented in tabular form expressing the molal volume as a function of temperature, pressure, and composition for 1225 states of the system.

The partial molal volume of each component of the system was computed by graphical methods. The results are presented in tabular form in which the partial molal volumes of methane, n butane, and decane are expressed as functions of temperature, pressure, and composition for the same 1225 states of the system employed in the tabulation of molal volume.

A discussion of some applications of partial volumes in the thermodynamic treatment of multicomponent systems is given.
