ABSTRACT:
The compressibility coefficient of liquid compositions in a liquid mixture are measured with a system comprising a separator vessel and a vessel forming a closable variable volume chamber. A quantity of liquid mixture is trapped in the chamber and the volume is reduced while measuring the pressure increase to determine the compressibility coefficient of a quantity of the liquid mixture. An incremental volume of one of the liquid component compositions is added to the liquid mixture in the chamber and the compressibility coefficient of the new liquid mixture is measured to determine the compressibility coefficient of the liquid component of the incremental volume. The compressibility factor of gas in the liquid mixture may also be determined by compressing a quantity of the gas and fitting a polynomial equation to the pressure-volume relationship.
