Production of Methane Hydrate Inhibitor: Study on N-Methyl-2-Pyrrolidone as Kinetic Hydrate Inhibitor

This paper discuss on effectiveness of N-Methyl-2-Pyrrolidone (NMP) as kinetic hydrate inhibitor compared to Polyvinylpyrrolidone (PVP). Through the experiment, hydrate phase equilibrium of pure methane, NMP and PVP are determined. This will help in understanding the phase equilibrium behavior and effect on the phase equilibrium line using different inhibitor; NMP and PVP.
Due to insufficient experimental data for this study in open literature and methane hydrate plugging with regard to pipeline flow assurance matter, it has made production of hydrate inhibitor study is important in order to deal with hydrate formation in pipeline. The experiment is carried out by using HYDREVAL equipment in high pressure and low temperature to obtain the phase equilibrium of NMP and PVP.
The findings of this study will give better design of industrial operation in such a way that prevention of gas hydrate formation can be achieved by understanding the behavior of gas hydrate and inhibitor.
