| 摘要 |
<p>The invention relates to a method and a device for regenerating a scrubbing medium (21) that is used at elevated pressure in a physical gas scrubber for purifying a feed gas (1) containing hydrogen and carbon monoxide and in the process is loaded with carbon dioxide and sulphur components. The scrubbing medium (21) loaded with carbon dioxide and sulphur components is expanded (j,B) to a pressure between 0.4 and 1.7 bar(a), preferably between 1.0 and 1.3 bar(a) and carbon dioxide-rich, sulphur component-containing gas (23) that is liberated during the expansion is compressed (V2) and introduced into a scrubbing column (W), in which sulphur components are scrubbed out of the carbon dioxide-rich gas using sulphur-free scrubbing medium (18).</p> |
