Title:
熱利用型ガス精製システム
Document Type and Number:
Japanese Patent JP6994331
Kind Code:
B2
Abstract:
To provide a gas refining system utilizing heat of methanation reaction with improved efficiency.SOLUTION: The heat utilization type gas refining system comprises: a methane gas synthesizer that synthesizes methane gas using at least hydrogen and carbon dioxide as source gases, a source gas introduction passage for introducing the source gas into the methane gas synthesizer, a product gas delivery passage for delivering product gas generated by the methane gas synthesizer, a temperature swing adsorption type gas refining device provided through the source gas introduction passage and/or the product gas delivery passage for removing impurities in gas, and a regeneration gas introduction passage for introducing respectively a high temperature regeneration gas and a low temperature gas that drive a desorption process of the temperature swing adsorption type gas purification device into the temperature swing adsorption type gas purification device, wherein heat of a reaction of the methane gas synthesizer is applied to high temperature regeneration gas sent through the regeneration gas introduction passage.SELECTED DRAWING: Figure 1
