Abstract:
A gas specimen mixture analysis system includes at least one sensor for measuring the concentrations of inert components in the gas specimen mixture, a pressure sensor for measuring the pressure of the gas specimen mixture, and a temperature sensor for measuring the temperature of the gas specimen mixture. A subsystem measures the speed of sound in the gas specimen mixture, and a processing subsystem, responsive to the at least one inert component sensor, the pressure sensor, the temperature sensor, and the subsystem for measuring the speed of sound, is configured to generate a number of sample gas mixtures with varying percentages of hydrocarbon gases, each including the measured inert component concentrations. The processing subsystem is also configured to calculate, for each generated sample gas mixture, the speed of sound therein based on the measured pressure and temperature and the particular percentages of hydrocarbon gases therein, and iteratively compare the measured speed of sound with the calculated speed of sound in different sample gas mixtures until convergence for a particular sample gas mixture. The processing subsystem is further configured to calculate the molecular weight of the particular sample gas mixture and set the molecular weight of the gas specimen mixture to the calculated molecular weight.
