On Calculation of Some Properties of Natural Gas Using a Limited Number of Experimental Parameters

Abstract

Some calculation aspects of natural gas properties based on limited numbers of initial experimental parameters, namely temperature, pressure, and speed of sound, were considered. The application possibilities for a wide range of compositions, temperatures, and gas mixtures pressure, simulating natural gases of various fields using the previously proposed Farzaneh-Gord method were discussed. It has been shown, that this method, in reality, yields fairly accurate results, calculating molecular weight of natural gas and its density. We note that good calculation results of mass flow rate make it possible to recommend this method for practical express calculations.
