Abstract
The present invention relates to the use of a specific group of acylated nitrogen-containing compounds as anti-agglomerants for gas hydrates. The anti-agglomerants are surface active nitrogen-containing compounds with 1-7 nitrogen atoms, which compounds have at least two hydrophobic groups with 6-24 carbon atoms, and where the hydrophobic groups are connected to the remainder of the molecule by an amine moiety or an amide moiety, and which compounds have at least one C2-C5 acyl group; or a salt thereof. The invention also relates to a method for inhibiting the agglomeration of gas hydrates in a conduit, and compositions comprising the gas hydrate anti-agglomerant, a corrosion inhibitor and/or a paraffin deposition inhibitor.
