Abstract

Accurate estimation of natural gas water content is very important and crucial for proper handling of many natural gas production and processing operations. In this paper, a new mathematical expression is developed for accurate estimation of the water content of sweet natural gas in equilibrium with liquid water for temperatures from 298.15 to 413.15 K as well as pressures between 3 to 80 MPa. The average absolute deviation percent is 0.86% and it proves the excellent agreement of predicted values using new correlation in comparison with reported data in the literature. The precision of new correlation to predict the water content of natural gas could not be provided by any of the other investigated methods. The excellent performance of the proposed correlation along with its simplicity and uncomplicatedness enable accurate and fast estimation of natural gas water content for any natural gas industrial applications.
