Treatment of produced hydrocarbon fluid containing water

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. A system for treatment of a flow of fluid hydrocarbon fluid containing water includes the following elements listed in the flow direction and connected with each other: connection to a hydrocarbon production source (), a first separator () operative to separate at least free water from said fluid flow, a converting system () for converting free/condensed water to gas hydrate, a pipeline () for transporting a dry gas or condensate/oil; and in addition a line (') which leads from the converting system () to the first separator () providing a first recycling flow including gas hydrates.
