Natural gas must be transported from a gas field to areas of demand, therefore accurate and reliable thermophysical properties of natural gas, which are difficult to obtain by experimental methods, are required in the design of natural gas pipelines. The aim of this study is to calculate PVT properties of natural gas in the conditions of transportation in pipelines by Monte Carlo (MC) molecular simulation. In this paper the accuracy of calculated values and the choice of potential models are discussed. For multicomponent systems like natural gases composed of methane, ethane, propane, carbon dioxide and nitrogen, uncertinty of the calculated PVT values by the MC method is estimated to be less than ±1.5% in pressure. Features of PVT properties of natural gases produced in several areas are predicted.
