The Structure and Formation of Gas Hydrates

Part of the Green Energy and Technology book series (GREEN)


The third chapter explains to the reader how and why gas hydrates form from water (or ice) and small gas molecules, such as methane, carbon dioxide, and many other gases. The hydrate crystal structures are described as well as the conditions (mainly pressure and temperature) at which they are stable. This includes the most common hydrate phase equilibrium behavior, detailed in phase diagrams. Methods are also described for preventing hydrate formation by adding inhibitors, which shift the hydrate stability conditions, taking into account developments that have emerged in recent times.
