A process for removal of non-polar compounds from water, wherein the non-polar compounds exist in dissolved or dispersed form, wherein the water is led through a preparation tank wherein the temperature is adjusted and wherein possible solid particles are removed. The water is then led via pipe into a reactor tank and is mixed with a hydrate forming compound, wherein simultaneously hydrate seeds are added which have been recycled for continuous use in the process; whereby the drops or molecules of the non-polar compounds are attached or associated to hydrate particles being formed in the reactor tank. The hydrate particles are separated from the water and melted. The hydrate forming compound is recycled to the reactor tank and the non-polar compounds discharged. In addition, a device for use of the process as well as hydrates for removal of non-polar compounds in water.

Method for treatment of water comprising non-polar compounds

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.

Treatment of produced hydrocarbon fluid containing water

The present invention concerns a method for purification of contaminated water through hydrate formation and separation of hydrates from contaminated water enriched with contaminants, by supplying hydrate particles to the water during hydrate formation. The present invention also concerns a device for purification of water by using a method according to the invention, and water produced according to the invention. By using the process principles according to the present invention, all types of water can be purified for consumption or safe discharge, or desired resources can be recovered, and air can be purified if it first is bubbled through the water which then is purified by a method according to the invention.

Method for purification of contaminated water

A method and a system for transporting a flow of fluid hydrocarbons containing wax and/or asphaltenes or any other precipitating solids through a treatment and transportation system including a pipeline are disclosed. The flow of fluid hydrocarbons is introduced into a reactor (), where it is mixed with another fluid flow having a temperature below a crystallization temperature for the wax and/or asphaltenes or other solids and containing particles or crystals acting as nucleating and/or growth cores for the wax and/or asphaltenes or other solids, the mixing temperature providing precipitation of the wax and/or asphaltenes or other solids from the flow of fluid hydrocarbons, and the effluent flow of hydrocarbons and particles is conveyed from the reactor () to a pipeline () for transportation.

Method and system for transporting flows of fluid hydrocarbons containing wax, asphaltenes, and/or other precipitating solids

A method of transporting a flow of fluid hydrocarbons containing water through a treatment and transportation system including a pipeline, wherein the flow of fluid hydrocarbons is introduced into a reactor where it is mixed with particles of gas hydrates which are also introduced into the reactor. The effluent flow of hydrocarbons from the reactor is cooled in a heat exchanger to ensure that all water present therein is in the form of gas hydrates. The flow is then treated in a separator to be separated into a first flow and a second flow. The first flow has a content of gas hydrate and is recycled to the reactor to provide the particles of gas hydrates mentioned above. The second flow is conveyed to a pipeline to be transported to its destination.
