| 摘要 |
A method of treatment of hydrocarbon fluid flowing through a pipeline comprises 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 flowline and downstream thereof cooling the gas in said pipeline to a temperature close to or below the water dew point thereof thereby condensing 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. Water condensed in this manner may be removed by a water separator and inhibitor trapped in such water can be recovered and reused. |
