Abstract

AbstractA model is presented for the prediction of pressure and temperature profiles in a high pressure gas pipeline. Using the BWR equation of state to predict the properties of the gas, an analytical approach reduces the problem to two nonlinear equations which can be solved numerically. Rigorous thermodynamic treatment of the energy and flow equations results in a model which yields good agreement with published data for high pressure natural gas pipelines. The model is also shown to predict frictional heating during the adiabatic flow of dense phase hydrocarbons.
