Dual Effect of Low‐Dosage Poly(Ethylene Oxides) on Methane Hydrate Formation
Abstract Time‐dependent isochoric formation of methane hydrate was investigated in the presence of low‐dose poly(ethylene oxides) (PEOs). The effect of different molecular weights of PEO on methane hydrate nucleation time and storage capacity was studied and compared. Kinetic measurements revealed a...
