A procedure for the calculation of the natural gas molar heat capacity, the isentropic exponent, and the Joule–Thomson coefficient

A numerical procedure for the computation of a natural gas molar heat capacity, the isentropic exponent, and the Joule–Thomson coefficient has been derived using fundamental thermodynamic equations, DIPPR AIChE generic ideal heat capacity equations, and AGA-8 extended virial-type equations of state. The procedure is implemented using the Object-Oriented Programming (OOP) approach. The results calculated are compared with the corresponding measurement data. The flow-rate through the orifice plate with corner taps is simulated and the corresponding error due to adiabatic expansion is calculated. The results are graphically illustrated and discussed.
