It is described a method for treating a flow of fluid hydrocarbons containing water wherein the flow of fluid hydrocarbons is introduced into a first separator 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 comprising gas hydrates, said first fluid flow is recycled into the first separator, and wherein the second fluid flow having a content of dry gas and/or condensate/oil. The invention also provides a system for treatment of a flow of fluid hydrocarbon fluid containing water, said system including the following elements listed in the flow direction and connected with each other: connection to a hydrocarbon production source (1), a first separator (3) operative to separate at least free water from said fluid flow, a converting system (5) for converting free/condensed water to gas hydrate, a pipeline (6, 18) for transporting a dry gas or condensate/oil; and in addition a line (7) which leads from the converting system (5) to the first separator (3) providing a first recycling flow comprising gas hydrates. |
