文摘

The thermodynamic and kinetic hydrates inhibition effects of addition of synergents poly(ethylene oxide) (PEO) and vinyl caprolactum (VCAP) with ionic liquids 1-methyl-1-propylpyrrolidinium chloride [PMPy][Cl] and 1-methyl-1-propylpyrrolidinium triflate [PMPy][triflate] were studied on a synthetic quaternary gas mixture (methane, C₁ = 84.20%; ethane, C₂ = 9.90%; n-hexane, C₆₊ = 0.015%; CO₂ = 2.46%; N₂ = 2.19%). The results show that the addition of synergents with ionic liquids helps to improve their thermodynamic and kinetic hydrate inhibition effectiveness simultaneously.
