ABSTRACT:
Systems for determining the gas compression exponent, k, and the compressibility factor, Z, include a chamber which may be reduced in volume while the pressure, temperature and volume changes are recorded. The system for determining compressibility factor includes a temperature controller and heat exchanger which varies the temperature in the chamber after a compression process or while holding the volume of the chamber constant during multiple temperature changes. Values of pressure, temperature and volume are measured at all conditions. The compression exponent is measured by extrapolating a curve of pressure versus time while allowing the temperature of the gas to decay from heat exchange with the structure forming the chamber. The compressibility factor is determined by comparing the ratios of compressibility factors at three separate conditions of pressure, volume and temperature using an iterative technique based on an equation which utilizes a curve fitted form of the Standing Katz diagram having variables which include a pseudo-reduced temperature.
