- W4387237079 abstract "Experimental data on the dissociation of propane hydrate samples obtained from the bulk samples of ice and frozen aqueous solutions of polyvinylpyrrolidone are presented. It was revealed that propane hydrate exhibits a self-preservation effect, with a meager dissociation rate when subjected to a sudden drop in pressure in the presence of polyvinylpyrrolidone . This phenomenon occursat temperatures below 271 K. The results of the experiments made it possible to establish the range of polyvinylpyrrolidone concentration in frozen aqueous solutions, as well as estimate the thickness of the ice crust formed on the gas hydrate surface during dissociation,at which the self-preservation effect of propane hydrate is realized. It has been experimentally established that the shielding effect of the ice crust of preserved propane hydrate is retained up to a temperature of 272 K and completely disappears near 273 K." @default.
