Quantitative understanding of the water content of pipeline fluids in equilibrium with hydrates is critically important to ensure pipeline flow without hindrance from solid precipitation. This paper focuses on pipelines with CO<inf>2</inf>-rich fluids in cold environments (such as those in Alaska) and generally in CO<inf>2</inf> capture. Since there is considerable question about the available data for the water solubility in CO<inf>2</inf> at these conditions, a round-robin testing program was structured by Fluor/Worley Parsons Arctic Solutions to quantitatively establish the water solubility. The goal of the data program was to determine the water solubility in CO<inf>2</inf>-rich mixtures to estimated uncertainty. This paper presents the data program and evaluates its results through thermodynamic analysis and comparison to available literature data.
