Process and plant for producing carbon monoxide

CO prodn. comprises medium pressure distillative sepn. from a mixt. of CO, H2 and other constituents such as N2 and CH4, involving initial sepn. of the CH4, followed by sepn. of the CO. The liq. is used at low pressure to cool the head of one of the sepn. columns and is withdrawn at an intermediate...

Zusammenfassung:	CO prodn. comprises medium pressure distillative sepn. from a mixt. of CO, H2 and other constituents such as N2 and CH4, involving initial sepn. of the CH4, followed by sepn. of the CO. The liq. is used at low pressure to cool the head of one of the sepn. columns and is withdrawn at an intermediate location of the column to ensure reflux of the other column. Also claimed is an installation for CO prodn. using the above method.
