Abstract
A process for removing water from a natural gas in an underwater environment is described. The process comprises dehydrating a natural gas feed stream in an apparatus arranged to exchange heat with the underwater environment, preferably including the step of forming hydrates in a hydrate forming zone of a hydrate vessel. The step of forming hydrates in the hydrate zone may comprise the step of introducing the natural gas feed stream into the hydrate vessel through an expansion device with the expansion device is located at and defines a gas inlet to the hydrate vessel. Heat exchange with the hydrate vessel itself need not occur as in one embodiment, heat exchange with the underwater environment takes place through an arrangement of pipes upstream of the hydrate vessel.
