The Natural Gas Composition is Key in Hydrate Formation

Jerome Rajnauth


This analysis will evaluate the effects of the natural gas composition on the formation of hydrate for the purpose of storage and transporting natural gas.
Results show that the composition of the natural gas can affect the temperature and pressure required for formation of the hydrate. Carbon dioxide, hydrogen sulfide and nitrogen impurities in natural gas affect the hydrate formation and may result in additional processing of the gas is required hydrate formation.
The composition of the sample also affects the water to gas mole ratio and hence the amount of water required for hydrate formation.
