Some Features of the Formation of Polycrystalline Conglomerates of Methane Hydrate at the Interface Foam—Solution of Surfactants

The paper presents an experimental study of the process of methane hydrate formation from stabilized water foam. In all cases, the hydrate formation front started from the region inside the foam. Upon reaching the foam-solution boundary, it initiated the formation of polycrystalline conical conglomerates at this boundary - hydrate needles oriented deep into the solution. A mechanism for their formation and subsequent spontaneous shortening of some of them is proposed.
