TREATMENT OF PRODUCED HYDROCARBON FLUID CONTAINING WATER

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...

Zusammenfassung:	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. L'invention porte sur un procédé pour le traitement d'un flux d'hydrocarbures liquides contenant de l'eau, le flux d'hydrocarbures liquides étant introduit dans un premier séparateur séparant au moins l'eau libre dudit flux d'hydrocarbures liquides, le reste dudit flux d'hydrocarbures liquides étant introduit dans un système convertissant l'eau libre/condensée présente dans le flux d'hydrocarbures liquides dans ledit système en hydrates de gaz, et produisant au moins un premier flux de liquides et un second flux de liquides, ledit premier flux de liquides étant une phase liquide comportant des hydrates de gaz, ledit premier flux de liquides étant recyclé dans le premier séparateur, et le second flux de liquides ayant une teneur en gaz sec et/ou en condensat/huile. L'invention porte également sur un système de traitement d'un flux d'hydrocarbures liquides contenant de l'eau, ledit système comprenant les éléments suivants énumérés dans le sens de la circulation et reliés les uns aux autres : un raccordement à une source de production d'hydrocarbures (1), un premier séparateur (3) pouvant fonctionner pour séparer au moins l'eau libre dudit flux de liquid
