PROCESS FOR SEPARATING CARBONIC ACID GAS FROM METHANE-RICH GAS |
摘要 |
<p>A process for separating and recovering carbonic acid gas from a methane-rich gas containing the same by a pressure swing means comprising contacting the methane-rich gas with an adsorbent for carbonic acid gas at a high pressure to obtain a refined methane gas and then desorbing the carbonic acid from the carbonic acid gas-adsorbed adsorbent at a low pressure to obtain a substantially pure carbonic acid gas.</p> |
