Sažetak

This work summarizes the current understanding of formation and stability of natural gas hydrates - clathrates of methane encaged in crystalline lattice of water - with emphasis on their role as a hazard in natural gas pipelines. A novel method of hydrate formation inhibition is proposed that is based on creation of a metastable state between structure I and II clathrates by changing partial pressures of methane and ethane in natural gas flow. The work encourages future experiments that would look at the range of partial pressures of ethane added to methane gas that would lead to clathrate formation suppression.
