COMPOSITION FOR INHIBITING FORMATION OF GAS HYDRATES Russian patent published in 2020 - IPC C09K8/524 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to oil and gas industry and can be used in production, preparation and transportation of hydrocarbon raw material. Composition for inhibiting formation of gas hydrates, containing a thermodynamic inhibitor - methanol and ethylene glycol, kinetic inhibitor and water, as a kinetic inhibitor contains urotropin or neopentyl polyol - 2,2-dimethylolpropane, or trimethylolpropane, or 2,2-bis(hydroxymethyl)propane-1,3-diol, with the following ratio of components, wt. %: methanol 67.3–74.3, ethylene glycol 11.7–14.3, urotropin or neopentyl polyol 0.5–2.0, water is the balance.

EFFECT: technical result is higher inhibition of gas hydrates in hydrocarbon liquids and gases containing water and reduced environmental consequences of using the inhibitor.
