  • Patent number: 9068451
    Abstract: A method for treating a flow of fluid hydrocarbons containing water includes introducing the flow of fluid hydrocarbons into a first separator and separating at least free water from said flow of fluid hydrocarbons, wherein a remainder of said fluid hydrocarbon flow is introduced into a system converting free/condensed water in the fluid hydrocarbon flow in said system to gas hydrates, and providing at least a first fluid flow and a second fluid flow, wherein said first fluid flow is a liquid phase including gas hydrates, said first fluid flow is recycled into the first separator, and wherein the second fluid flow has a content of dry gas and/or condensate/oil.
