The present disclosure provides a process for continuously producing clathrate hydrate. This process includes the step of: (a) pressurizing a hydrate-forming gas to an elevated pressure and cooling the hydrate-forming gas below the gas- water-hydrate equilibrium point at the elevated pressure; (b) cooling liquid water below the gas-water-hydrate equilibrium temperature for the elevated pressure; (c) charging hydrate-forming gas at the elevated pressure into a reaction zone which contains a movable surface; (d) atomizing water in the reaction zone in contact with the hydrate-forming gas to form gas hydrate in the reaction; (e) depositing the gas hydrates on the movable surface; and (f) collecting the gas hydrates from the movable surface.

La présente invention concerne un procédé de production continue d'hydrate de clathrate. Le procédé consiste à a) mettre en pression un gaz de formation d'hydrate à une pression élevée, puis refroidir le gaz de formation d'hydrate au-dessous du point d'équilibre gaz-eau-hydrate à la pression élevée; b) refroidir de l'eau liquide au-dessous de la température d'équilibre gaz-eau-hydrate pour la pression élevée; c) charger le gaz de formation d'hydrate à la pression élevée dans une zone de réaction contenant une surface mobile; d) pulvériser l'eau dans la zone de réaction en présence du gaz de formation d'hydrate pour former des hydrates de gaz dans le milieu de réaction; e) déposer les hydrates de gaz sur la surface mobile; et f) retirer les hydrates de gaz de la surface mobile.
