- •
This work illustrates the inhibition and decomposition mechanism of gas hydrate in presence of polyvinylpyrrolidone at molecular level.
- •
Free energy of binding of polyvinylpyrrolidone with hydrate surface was calculated.
- •
Higher molecular weight of polyvinylpyrrolidone has greater binding affinity with gas hydrate surface.
- •
Enhanced decomposition kinetics was observed in the presence of polyvinylpyrrolidone polymer.
