A method is disclosed for transport of hydrocarbons in a pipeline flow across large distances, from a first location at an offshore hydrocarbon reservoir to a second location. At said first location a liquid absorbent is provided in the form of a gas-poor hydrocarbon liquid flow. A flow of gas saturated hydrocarbon liquid and released associated hydrocarbon gas is supplied to the gas-poor liquid flow at first location, the volume of gas-poor hydrocarbon liquid being selected so as to be sufficient for all released associated hydrocarbon gas to be absorbed by the gas-poor hydrocarbon liquid. Then the hydrocarbon liquid with absorbed hydrocarbon gas is transported to said second location. A plant for transport of hydrocarbons in a pipeline flow is also disclosed. The plant comprises an absorption chamber (6) at a first location. Absorption chamber (6) is connected to a well pipe (3). At a second location a separator plant (9) is provided. A first pipeline extends from the liquid portion of separator plant (9) to absorption chamber (6). A second pipeline (7) connects absorption chamber (6) with separator plant (9). In said first pipeline (10) the flowing medium can be pressurized by the aid of a high pressure pump (11).
A method for transporting hydrocarbons in a pipeline over long distances, from a first location at an offshore hydrocarbon source to a second location, comprising the steps of providing, at the first location, an absorbent including a gas-poor hydrocarbon liquid, supplying a flow of gas saturated hydrocarbon liquid and released associated hydrocarbon gas from the hydrocarbon source to said gas poor hydrocarbon liquid adjacent said first location, the volume of gas-poor hydrocarbon liquid being selected to be large enough to permit all released associated hydrocarbon gas to be absorbed by said gas-poor hydrocarbon liquid, flowing said hydrocarbon liquid with absorbed hydrocarbon gas to said second location, separating the hydrocarbon gas from said hydrocarbon liquid with absorbed hydrocarbon gas at said second location to provide said gas-poor hydrocarbon liquid flow that is supplied at said first location.
A plant for use in transporting hydrocarbons in a pipeline flow across long distances, from a first location at an offshore hydrocarbon source to a second location, comprising an absorption chamber at said first location and connected to the hydrocarbon source, a separator plant at said second location for separating hydrocarbon gas from hydrocarbon liquid to produce a gas-poor hydrocarbon liquid, a first pipeline for flowing at least part of the gas-poor hydrocarbon liquid from said separator plant to said absorption chamber, and a second pipeline for flowing the hydrocarbon liquid with absorbed hydrocarbon gas from said absorption chamber to the separator plant, and means for pressurizing the gas-poor hydrocarbon liquid in said first pipeline.
