AI Article Synopsis

  • Water bound to kinetic inhibitors in tetrahydrofuran and natural gas hydrates relaxes in less than a millisecond.
  • The quantity of this water is linked to how long the inhibitors prevent rapid crystallization of hydrates.
  • The hydrophobic hydration effect of these inhibitors plays a role in this process.

Article Abstract

Water tightly bound to the kinetic inhibitors of tetrahydrofuran hydrate and natural gas hydrate has a relaxation time scale of sub-milliseconds. The amounts of such water are related to the inhibition time before rapid growth of the hydrate crystals and the hydrophobic hydration effect of the inhibitors.
