Abstract: The invention provides a method of treatment of hydrocarbon fluid flowing through a pipeline comprising an in-field flowline and downstream thereof a larger internal cross-sectional area trunkline, said method comprising introducing a gas hydrate formation inhibitor into hydrocarbon gas at a site in said pipeline and downstream thereof cooling the gas in said pipeline to a temperature close to or below the water dew point thereof whereby to condense water from the gas such that the water dew point of the gas entering said trunkline is close to or lower than the ambient temperature.

Abstract: The present invention provides a method of inhibiting formation of solid hydrates in a conduit (10) used to contain a flowing, water-containing hydrocarbon, which method comprises introducing into said hydrocarbon in said conduit a gas (4, 5, 6) which raises the pressure threshold for hydrate formation for said water-containing hydrocarbon, said gas being introduced in a manner which causes it to travel along at least part of said conduit in the direction of hydrocarbon flow.
