C124 Experimental Study on Gas Hydrate Formation with Methane, Ethane and Propane Gas Mixture

Abstract

Hydrate formation behavior of mixed gases of methane, ethane and propane has been studied as a model examination of NGH (Natural Gas Hydrate) production, because it is expected to be a novel transportation medium of natural gas. A batch-wise experiments were carried out with the initial gas phase composition corresponding to the equilibrium state which is calculated by using CSMHYD program. It has been found that the effect of the pressure on the amount of hydrate gas was small and the production rate of the mixed gases was nearly equal to that of methane.
