Title:
METHOD AND APPARATUS FOR CRYOGENIC SEPARATION OF A MIXTURE CONTAINING AT LEAST CARBON MONOXIDE, HYDROGEN AND NITROGEN
Document Type and Number:
WIPO Patent Application WO/2015/044575
Kind Code:
A3
Abstract:
The invention relates to an apparatus for cryogenic separation of a mixture of carbon monoxide, hydrogen and nitrogen, including a stripping column (2) and a denitrogenation column (4), a pipe for sending the mixture (13) in liquid form to the head of the stripping column, a pipe for removing a liquid depleted of hydrogen (15, 16) connected to the stripping column, a pipe for removing a gas enriched with hydrogen (14) from the stripping column, means for sending the liquid depleted of hydrogen (16) or a fluid derived from said liquid to the denitrogenation column, a pipe for drawing a liquid (22) enriched with carbon monoxide from the denitrogenation column, a pipe for drawing a gas (21) enriched with nitrogen from the head of the denitrogenation column and means for sending at least one portion of the gas enriched with hydrogen to the denitrogenation column.
