Abstract
Saturated and unsaturated carboxylic fatty acids and alkylamine salts, alkyl esters and alkyl amide derivatives of these fatty acids are effective in improving the lubricity of hydrate inhibitor formulations, thereby effectively reducing the level of wear on moving parts of a pump under a load during pumping of the hydrate inhibitor formulation, for instance into an umbilical for a subsea hydrocarbon production operation.
