FIELD: cleaning and separation of natural and oil gases.
SUBSTANCE: proposed method of cleaning natural gas from admixtures includes bringing the natural gas in contact with aqueous medium in reactor at initial thermobaric conditions characterized by pressure ensuring formation of hydrates of main component of natural gas - methane and compounded hydrates of natural gas enriched with mixture components, for example hydrogen sulfide, propane and butane. After settling of first hydrates, initial pressure in reactor is reduced to magnitude below equilibrium pressure of methane hydrate formation but above equilibrium pressure of hydrate formation for natural gas to be cleaned. Used as aqueous medium is aqueous solution of surfactants.
EFFECT: increased productivity; high degree of cleaning; reduced power requirements and capital outlays per unit of mass of gas to be cleaned.
