Abstract

A device for cryogenically separating a synthesis gas comprises a heat exchanger (5) in which the synthesis gas is cooled, a washing column (C1), at least one conduit for conveying the cooled synthesis gas to the washing column, a conduit (19) for discharging a gas enriched in hydrogen at the head of the washing column, a column (23) for discharging a liquid enriched in carbon monoxide and/or in methane from the tank of the washing column, a conduit (61) for conveying the tank liquid or a liquid derived from the tank liquid, optionally after expansion, to a CO/CH4 separation column (C2), a conduit (25) for withdrawing a liquid enriched in methane from the tank of the CO/CH4 separation column, a conduit for withdrawing a fluid enriched in carbon monoxide from the head of the CO/CH4 separation column, means for pressurising at least a portion of the fluid enriched in carbon monoxide, a conduit for conveying at least a portion of the pressurised fluid to the head of the washing column, the washing column comprising a tank reboiler (R1) for heating the tank of the washing column.
