Methane is a greenhouse gas that burns to form carbon dioxide (CO2) and water vapor. (CO2) is 25 times less potent than methane when emitted into the atmosphere with regards to global warming. Concentrations of methane in ventilation exhaust air of coal and trona mines are very dilute; typically below 1% and often below 0.5%. Flow rates are so high that ventilation air methane constitutes the largest source of methane emissions at most mines. This methane emission wastes energy and contributes significantly to global greenhouse gas (GHG) emissions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ventilation air methane thermal oxidizer」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
