Compounds comprising multiple hydrophilic heads and a lipophilic tail may be employed into fluids to inhibit agglomeration of hydrates, among other things. Suitable hydrophilic heads may include secondary, tertiary, and/or quaternary ammonium cation moieties, phosphonium cation moieties, and combinations thereof. Such LDHI compounds may provide enhanced interactivity with hydrate crystals and/or hydrate-forming molecules. These compounds may be employed in fluids in various environments, such as a conduit penetrating a subterranean formation, or a conduit carrying fluid in an industrial setting.

Multiple hydrophilic head hydrate inhibitors

A method of controlling corrosion in a subsea pipeline is disclosed which includes supplying a low dose inhibitor stream (LDHI) comprised of a quaternary amine and drying with a desiccant.

Water removal from anti-agglomerate LDHIs

A method of inhibiting gas hydrate formation in petroleum and natural gas production systems through the use of low dosage hydrate inhibitors which include reaction products of non-halide-containing inorganic acids, organic acids, and organic amines. The use of these non-halide-containing reaction products rather than chloride containing acids or alkylating agents avoids corrosion and stress cracking caused by residual inorganic chloride and other inorganic, halide-containing acids. The anti-agglomerate compositions can be administered continuously to effectively inhibit gas hydrate formation. In preferred embodiments, the anti-agglomerate compositions are mixtures of reaction products of non-halide-containing organic acids and organic amines.
