Abstract

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.
