REMOVAL OF INERTS FROM NATURAL GAS USING HYDRATE FORMATION

摘要

A method for separating a gas stream comprising methane and a contaminate gas comprises the steps of contacting the gas stream with water under temperature and pressure suitable for the formation of methane hydrates so as to form a water/hydrate slurry, separating the contaminte gas from the water/hydrate slurry, and recovering methane from the water/hydrate slurry so as to generate a water stream.
