MODELING OF INFLUENCE OF COMPONENT COMPOSITION AND HUMIDITY OF NATURAL GAS ON ITS THERMOPHYSYCAL CHARACTERISTICS

Abstract

The influence of natural gas humidity and component composition on its thermophysical characteristics has been studied. The analysis of the last researches of qualitative characteristics of natural gas in the field of thermoanemometry was given. The physical meaning of the main studied thermophysical characteristics of natural gas - thermal conductivity and heat capacity was explored in the operation of the thermoanemometric sensor. Based on computer simulations, a qualitative and quantitative relationship between the thermophysical characteristics of natural gas and its component composition and humidity has been established. The influence of changes in humidity and composition of natural gas (methane, ethane, propane, butane, pentane, nitrogen, carbon dioxide) on its thermophysical characteristics was modeled and the quantitative analysis of such influence was carried out.
