A composition is provided herein for preventing or retarding the formation of gas hydrates or for reducing the tendency of gas hydrates to agglomerate, during the transport of a fluid comprising water and a hydrocarbon, through a conduit. The composition is a homopolymer of an N-alkyl(meth)acrylamide, N,N-dialkyl(meth)acrylamide or copolymers thereof with N-vinyl-N-methylacetamide, in a defined solvent, which homopolymers and copolymers are made and applied in the defined solvent, which, most preferably, is a low molecular weight glycol ether such as 2-butoxyethanol.

Method for preventing or retarding the formation of gas hydrates

A composition for preventing or retarding the formation of gas hydrates during the transport of a fluid comprising water and a hydrocarbon through a conduit. The composition is a homopolymer of vinyl caprolactam, or copolymers thereof, having a low molecular weight in the range of 500 to 2500, which is made in a polymerization solvent, preferably a glycol ether, most preferably 2-butoxyethanol and also including a carrier solvent, preferably monoethylene glycol.

Described herein is a process of corrosion inhibition of a steel pipeline during transport of water and gas, or water and an oil, or mixtures thereof, therethrough, including introducing a copolymer of vinyl caprolactam and vinylpyridine into said pipeline.

Corrosion inhibition during transport of water and a hydrocarbon through a pipeline

A gas hydrate inhibitor includes, by weight, a copolymer including about 80 to about 95% of polyvinyl caprolactam (VCL) and about 5 to about 20% of N,N-dialkylaminoethyl(meth)acrylate or N-(3-dimethylaminopropyl) methacrylamide.

Gas hydrate inhibitor

A composition for preventing or retarding the formation of gas hydrates during the transport of a fluid comprising water and a hydrocarbon through a conduit. The composition is a copolymer of vinyl caprolactam and vinyl pyridine, and terpolymers thereof, with vinyl pyrrolidone, preferably including 70-97% by weight vinyl caprolactam. Suitably such polymers have a molecular weight in the range of 500 to 2500, and are made in a polymerization solvent, preferably a glycol ether, most preferably, 2-butoxyethanol; and also including a carrier solvent, preferably monoethylene glycol.

A composition for preventing or retarding the formation of gas hydrates during the transport of a fluid comprising water and a hydrocarbon through a conduit. The composition is a homopolymer of vinyl caprolactam, or copolymers thereof, having a low molecular weight in the range of 500 to 4000, which is made by polymerization of the monomer or monomers in a polymerization solvent which is a mixture of a glycol ether and water, preferably 2-butoxyethanol and water, at a pH of about 8-12.

Method for preventing or retarding the formulation of gas hydrates

A composition is provided herein for preventing or retarding the formation of gas hydrates or for reducing the tendency of gas hydrates to agglomerate, during the transport of a fluid comprising water and a hydrocarbon, through a conduit. The composition is a homopolymer of vinyl caprolactam having the low molecular weight in the range of 500 to 2500, or copolymers or terpolymers thereof, and a polyoxyalkylenediamine or a polyoxyarylenediamine. Such homopolymers, copolymers and terpolymers, preferably are made and applied in the defined solvent, which, most preferably, is a glycol ether such as 2-butoxyethanol.

Blend for preventing or retarding the formation of gas hydrates

A composition is provided herein for preventing or retarding the formation of gas hydrates or for reducing the tendency of gas hydrates to agglomerate, during the transport of a fluid comprising water and a hydrocarbon, through a conduit. The composition is a homopolymer of vinyl caprolactam having the low molecular weight in the range of 500 to 2500, or copolymers thereof, in a defined solvent. Such homopolymers and copolymers preferably are made and applied in the defined solvent, which, most preferably, is a glycol ether such as 2-butoxyethanol.
