Method and system for transporting a flow of fluid hydrocarbons containing water

A method for transporting a flow of fluid hydrocarbons containing water through a treatment and transportation system including a pipeline, the method comprising:

• introducing the flow of fluid hydrocarbons into a reactor, wherein the flow of fluid hydrocarbons contains water;
• introducing a cold fluid flow of hydrocarbons, containing particles of gas hydrates acting as a hydrophilic agent, into the reactor where it is mixed with the flow of fluid hydrocarbons containing water;
• cooling an effluent flow of hydrocarbons from the reactor in a heat exchanger to ensure that free water present therein attains the form of gas hydrates;
• treating the cooled effluent flow in a separator to separate the flow into a first flow and a second flow, wherein the first flow has a content of gas hydrate;
• recycling the first flow to the reactor to provide the particles of gas hydrate;
• and
• conveying the second flow to a pipeline to be transported to a destination.
