| 摘要 |
<p>The present disclosure relates to a methanation stage comprising at least one methanation reactor holding an amount of methanation catalyst, said reactor having an inlet for a stream of a feed gas rich in hydrogen and a carbon oxide, such as carbon monoxide or carbon dioxide, said reactor further being configured for directing said feed gas to contact said methanation catalyst, and where said methanation reactor further comprises an outlet for a stream of a methane rich gas having a higher temperature than said feed gas, where said methanation stage further comprises
a heat providing means for a heat exchange configured for heating said feed gas upstream said methanation reactor,
and a heat collecting means for a heat exchange configured for cooling said gas rich in methane downstream said methanation reactor,
characterized in that said two means for heat exchange are thermally connected by a heat transfer medium with the associated benefit obtained by the use of a heat transfer medium avoiding the process risk of leakages from the feed gas to the methane rich gas.</p> |
