20080308769 | Method for Simultaneously Producing Hydrogen and Carbon Monoxide - The invention relates to a method for simultaneously producing hydrogen and carbon monoxide consisting in generating a synthesis gas and in processing it by decarbonising and removing water and remaining carbon dioxide by passing said gas through a bed of adsorbents, in separating remaining components by forming at least one H2-rich flow, a CO flow containing at least one type of impurity selected from nitrogen and argon, a methane-rich purge gas flow and a flash gas flow. The inventive method also consists in regenerating the bed of adsorbents by passing a regeneration gas comprising at least one non-zero proportion of the formed H2flow and in recycling at least the purge and flash gases for feeding the synthesis gas generation stage. | 12-18-2008 |
20120067081 | Process And Plant For Recovering Argon In A Separation Unit For A Purge Gas Used In The Synthesis Of Ammonia - A plant for producing an argon-rich stream from a mixture formed by a purge fluid in an ammonia production plant comprises: at least one phase separator; a methane scrubbing column; a methane separation column; a nitrogen/argon separation column; a line for sending the mixture into at least one phase separator, to produce at least a hydrogen-enriched gas and a hydrogen-depleted liquid; a line for sending at least a portion of the hydrogen-depleted liquid into the bottom of the methane scrubbing column, to form an overhead gas and a bottoms liquid; a line for sending at least a portion of the bottoms liquid from the methane scrubbing column to the methane separation column, to produce a methane-enriched bottoms liquid and a methane-depleted overhead gas; a line for sending at least a portion of the methane-depleted overhead gas to the nitrogen/argon separation column, to form a nitrogen-enriched fluid as overhead of said column; a line for withdrawing an argon-rich liquid as bottoms of said column, serving as product; and a line for sending at least a portion of the methane-enriched bottoms liquid to the top of the methane scrubbing column. | 03-22-2012 |
20140305162 | Thermally Integrated Process and Apparatus for Purification and Separation of Components of a Synthesis Gas - Process for the purification and separation of a synthesis gas stream containing hydrogen, carbon monoxide and carbon dioxide in which synthesis gas is purified in a purification unit (W) involving a methanol washing step to remove carbon dioxide, the carbon dioxide depleted synthesis gas is purified by adsorption (P) to produce a purified synthesis gas stream and the purified gas stream is sent to a cryogenic separation unit (C) where it is cooled and separated by cryogenic separation in a column of a column system, at least one stream ( | 10-16-2014 |
