<p>The method involves decomposing a gas mixture (7) i.e. synthesis raw gas, through cleaning by a physically acting cleaning agent (1) in a normal operation such that methanol is utilized as the cleaning agent. Pressure ratios required for assembling a cleaning agent circuit are produced by auxiliary gas (6), which is related to infeed limit and introduced for gas cleaning. The auxiliary gas is guided through two pipes (4, 5), absorbed by the cleaning agent and formed as nitrogen. A regenerating device is provided beside an absorber column (A).</p> |
