Hoja1Calculate Water Content of Natural Gas with ExcelThis Excel
spreadsheet calculates the equilibrium water content of natural
gas. It uses a correlation derived from the McKetta-Wehe chart.
Originally published in 1958, the McKetta-Wehe chart is widely
accepted in the natural gas industry.There are several restrictions
inherent to the McKetta-Wehe chart.This chart is suitable for sweet
natural gas with a mole fraction of methane of more than 70%, and a
relatively small fraction of heavy hydrocarbons.Water content is
overestimated at pressures of 70 bar absolute and over.The
correlation is not suitable for natural gas in equilibrium with gas
hydrates. The water content of these is a complex function of their
composition and time. Thus few reliable correlations exist, and
thermodynamic models are usually used.The McKetta-Wehe chart should
only be used at temperatures below which hydrate would form.
