The Effect of Methanol on 512 Methane Hydrate Cage Cluster ¬– A Molecular Dynamics Study

Pal S, Kundu T. K

Abstract


Molecular dynamic simulation study of methane hydrate cluster having 27 methane encapsulated pentagonal dodecahedron (512) hydrate cage with and without presence of eight methanol molecules in supercell has been performed to evalute the effect of methanol on the stability and formation of methane hydrate cluster. Methanol is found to act as an effective methane hydrate inhibitor below 30 atm pressure for 240 K and below 90 atm pressure for 250 K. The prediction by this molecular dynamics simulation study is found to be well corresponds with reported experimental results.

 

Keywords: Methane hydrate, Pentagonal dodecahedron, Gas hydrate inhibitor
