METHOD OF INHIBITING FORMATION OF HYDRATES IN HYDROCARBON-CONTAINING RAW MATERIAL Russian patent published in 2016 - IPC E21B43/22 C09K8/524 

FIELD: technological processes.

SUBSTANCE: invention relates to methods of inhibiting formation of gas hydrates in different hydrocarbon-containing liquids and gases containing water and hydrate-forming agents, and can be used in processes of extraction, processing and transportation of hydrocarbon raw material to prevent formation of gas hydrates. Hydrocarbon-containing raw materials, including water and hydrate-forming components is treated with an inhibitor, in form of a composition containing a kinetic inhibitor, thermodynamic inhibitor and synergetic additive selected from a group comprising quaternary ammonium salts, ethylene glycol esters of general formula R₁OCH₂CH₂OR₂, where R₁ is a hydrogen atom or alkyl radical, R₂ is an alkyl radical, oxyethylated fatty alcohols, oxypropylated fatty alcohols, polyethylene oxide, polypropylene oxide, copolymers of ethylene oxide and propylene oxide or a mixture of said substances in following ratio of components, wt%: kinetic hydrate inhibitor 2.0-8.0; thermodynamic hydrate formation inhibitor 84.0-96.0; synergetic additive - balance, up to 100.

EFFECT: technical result is higher inhibiting capacity of described method compared to existing method.
