Dataset for the new insights into methane hydrate inhibition with blends of vinyl lactam polymer and methanol, monoethylene glycol, or diethylene glycol as hybrid inhibitors
Three-phase equilibrium conditions of vapor–aqueous solution–gas hydrate coexistence for the systems of CH(4)–H(2)O–organic thermodynamic inhibitor (THI) were experimentally determined. Hydrate equilibrium measurements for systems with methanol (MeOH), monoethylene glycol (MEG), and diethylene glyco...
