Abstract

In this chapter, several methods will be discussed which can be used to predict the water content of gases. Most of these methods are based on equations of state and rigorous thermodynamic models. Different methods of predicting water content of acid gas systems are evaluated based on the literature experimental data. In addition, the water content diagrams compatible with the experimental data for pure CO2, H2S, CH4 and their mixture are presented. These charts use for facility type calculations and trouble shooting. In another section, the gas solubility concepts will be reviewed. This section contains hydrocarbon gas solubility in water, non-hydrocarbon gas solubility in water, the calculation of gas solubility in water using Henry’s law constant and the effect of salinity on gas solubility. At the end of this chapter, a brief review has been conducted on the activity models.
