    Abstract: Controlling the formation of crystalline hydrates in various fluid systems, most notably, gas and oil transmission pipeline systems by contacting the systems with certain polymers or polymers associated with solid particles. The polymers useful are chelating polymers capable of interacting with charged gaseous molecules such as carbon dioxide, by removing the carbon dioxide, or more practically by scavenging for the carbon dioxide, to prevent the methane or ethane hydrate structures from forming since they require carbon dioxide to stabilize their structures.

    Abstract: The present invention provides improved methods of drying pipelines containing water which are to transport hydrate forming gaseous fluids. The methods basically comprise flowing a liquid which forms an azeotrope mixture with water into contact with water in a pipeline, the amount of the azeotropic liquid being sufficient to form an azeotrope mixture with the water whereby as the mixture is evaporated in the pipeline, the water concentration in the remaining mixture does not reach that concentration which will form hydrates with the hydrate forming gaseous fluid.

    Abstract: A process for transporting a fluid in a pipe under conditions where hydrates may form. In the process, the pipe fluid contains at least one of a gaseous hydrocarbon or liquid hydrocarbon and water and the water content is less than the liquid hydrocarbon content. The process includes the steps of 1) adding a dispersive additive in a hydrocarbon solution to the fluid to be transported, so as to form an emulsion, 2) transporting the liquid and gaseous hydrocarbons in the presence of water and the hydrates, 3) separating the gas phase, the hydrocarbon liquid in excess and a liquid hydrocarbon phase comprising the hydrates and the dispersing additive, and 4) separating the liquid hydrocarbon phase comprising the hydrates and the dispersing additives. The liquid hydrocarbon phase comprising the hydrates is separated by dissociating the hydrates to form a water-in-oil emulsion, the additives being solved in the oil or liquid hydrocarbon, and breaking the water-in-oil emulsion so as to obtain an aqueous phase and a liquid hydrocarbon comprising the additives. Finally the liquid hydrocarbon phase containing at least part of the dispersing additive from step 4, is recycled to a point in the pipe.

    Abstract: A natural gas compression heating process for regulating the operating temperature of the natural gas flowing through long pipelines in continuous permafrost and discontinuous permafrost regions. The heat obtained through compression of the natural gas, instead of actually heating as performed conventionally, is utilized to raise the temperature of the natural gas to only the desired operating temperature. Consequently, the locations of the natural gas compression heating process and compression stations along the pipeline in a permafrost region are determined by the flowing temperature profile of the pipeline instead of the conventional standard compression cost versus pipeline diameter analysis.
