Separation of hydrogen and carbon monoxide from a gas mixture uses a low temperature separation stage for a high purity with simultaneous production without surplus hydrogen |
| 摘要 |
For separation of a mixture of hydrogen and carbon monoxide in synthesis gas, it is passed through a decarbonizing unit (2) and a drying station (5), followed by a low temperature separation stage (6). The recycled gas containing at least 60% hydrogen, upstream of the decarbonizing unit, is composed of a gas (7) giving the low temperature separation and/or a portion (19) of the synthesis gas. The low temperature separation stage has a methane scrubbing column, a drainage column and a rectifying column. |
