METHOD FOR INHIBITING HYDRATE FORMATION |
摘要 |
A method for inhibiting the formation of gas hydrates within a fluid comprising a gaseous hydrocarbon phase, a liquid hydrocarbon phase and an aqueous phase which method comprises mixing a polymeric emulsifier and optionally a non-ionic non-polymeric co-emulsifier with the fluid prior to subjecting the fluid to conditions under which gas hydrates can be formed so as to generate a water-in-oil emulsion comprising a discontinuous aqueous phase, a continuous liquid hydrocarbon phase and a substantially gas impermeable interfacial layer comprising said polymeric emulsifier and optionally said non-ionic non-polymeric co-emulsifier wherein the aqueous phase is distributed in the continuous liquid hydrocarbon phase in the form of droplets and the substantially gas impermeable interfacial layer encapsulate s said droplets.
