Abstract

This disclosure relates to anti-agglomerant low dosage hydrate inhibitors that can inhibit the formation of hydrate agglomerants and/or plugs. The anti-agglomerant low dosage hydrate inhibitors may be surfactants. The hydrate inhibitors may be used for inhibiting, retarding, mitigating, reducing, controlling and/or delaying formation of hydrocarbon hydrates, agglomerants of hydrates, and/or plugs. The hydrate inhibitors may be applied to prevent, reduce, and/or mitigate plugging of conduits, pipes, transfer lines, valves, and other places or equipment where hydrocarbon hydrate solids may form. The hydrate inhibitors may be cationic ammonium surfactants having an ionizable secondary amine.
