Kinetics of Methane Hydrate Formation in Pure Water and Inhibitor Containing Systems

Abstract

Abstract: Kinetic data of methane hydrate formation in the presence of pure water, brines with single
salt and mixed salts, and aqueous solutions of ethylene glycol(EG) and salt+EG were
measured. A new kinetic model of hydrate formation for the methane-Fwater systems was
developed based on a four-step formation mechanism and reaction kinetics approach. The
proposed kinetic model predicts the kinetic behavior of methane hydrate formation in pure
water with good accuracy. The feasibility of extending the kinetic model to salt(s) and EG
containing systems was explored.

Key words: kinetics, hydrate formation, inhibitors, methane, brine
