Abstract
The present invention relates to a method for recovering methane gas by adding a gas mixture containing Nand COgases to natural gas hydrate and reacting them. The method for recovering methane gas from natural gas hydrate of the present invention comprises the step of replacing CHgas in natural gas hydrate with a gas mixture containing Nand COgases by adding the gas mixture to the natural gas hydrate. The method for recovering methane gas of the invention assures a recovery rate of CHgas much higher than prior art method without dissociating natural gas hydrate layer and utilization of flue gas as a gas mixture containing Nand COgases, which makes possible its practical application for the production of natural gas in terms of economy and environmental protection.
