Influence of low dosage hydrate inhibitors on gas hydrate formation condition is important for developments and chooses of combined hydrate inhibitors. By using polyvinylpyrrolidone aqueous solutions, Eexperimental data on the equilibrium conditions for methane hydrate in the presence of polyvinylpyrrolidone aqueous solutions with different concentrations within the temperature range from 282.6 K to 290.3 K in the temperature range of 282.6 K ~ 290.3 K were reported in this work. Measurements were made using an isochoric pressure-search method. The results show polyvinylpyrrolidone with the concentration from 0.5wt% to 15wt% has a little promoting effect on methane hydrate formation equilibrium conditions, and it is thought that addition of the polymer of polyvinylpyrrolidone can decrease the solution activity, but can increase the solubility of methane in this polymer solution.
