Claim:
1. A method of pumping a hydrate inhibitor composition, the method comprising: adding to the hydrate inhibitor composition an effective amount to increase lubricity of at least one lubricity agent selected from the group consisting of a C1-C36 carboxylic fatty acid, an alkylamine salt of a C1-C36 fatty acid, an alkyl ester of a C1-C36 fatty acid, an alkylphenol ester of a C1-C36 fatty acid, an alkanolamine salt of a C1-C36 fatty acid, an imidazoline salt of a C1-C36 fatty acid, an anhydride salt of a C1-C36 fatty acid, an alkanol amide of a C1-C36 fatty acid, an alkyl amide of a C1-C36 fatty acid, a polyetheramine salt of a C1-C36 fatty acid, and combinations thereof; and pumping the hydrate inhibitor composition containing the lubricity agent; where the hydrate inhibitor composition consists essentially of: an alcohol hydrate inhibitor selected from the group consisting of methanol, ethanol, monoethylene glycol, triethylene glycol and combinations thereof; and about 25 ppm to about 20,000 ppm of the lubricity agent; where the method has an absence of composition vaporization.
