Abstract

This invention is directed toward a method for inhibiting the formation (nucleation, growth and agglomeration) of clathrate hydrates. The method comprises adding into a mixture of hydrate forming substituents and water, an effective amount of a hydrate anti-agglomerate selected from the group consisting of anionic, cationic, non-ionic and zwitterionic hydrate anti-agglomerate. The hydrate anti-agglomerant has a polar head group and a nonpolar tail group said nonpolar tail group not exceeding 11 carbon atoms in the longest carbon chain.
