In a process for the combined production of a) a hydrogen-enriched gas and a carbon monoxide-enriched gas and/or b) a mixture of hydrogen and carbon monoxide by cryogenic distillation and scrubbing, a still liquor is extracted from a scrubbing column and sent to a stripping column, a still liquor is extracted from the stripping column and sent to a separating column for carbon monoxide and methane and a cooling fluid is used at a pressure greater than that of the head of the separating column for cooling at least one fluid extracted at an intermediate level from the scrubbing column.

Method and installation for cryogenic separation of a gaseous mixture by methane scrubbing

In a method for producing a gaseous mixture of CO and H, a first gas comprising at least 50% CO is compressed in a first compressor to form a first compressed gas cooled to a first temperature and mixes with a second gas comprising at least 50% hydrogen in order to form the gaseous mixture, at least one of the first and second gases originating from a cryogenic distillation separation unit in which a feed gas containing Hand CO cools in a first heat exchanger and is separated in at least one distillation column and at least one part of the second gas heats in the separation unit to a third temperature lower than the first temperature and is then sent to mix with the first gas.

Method and apparatus for producing a mixture of carbon monoxide and hydrogen

In a method for separating a synthesis gas containing carbon monoxide and hydrogen, a synthesis gas flow from a synthesis gas source is compressed in a compressor and separated into at least three gaseous products. If there is insufficient synthesis gas, at least three separation products are recycled in the compressor in order to separate said products.

Method and apparatus for separating a synthesis gas

The invention relates to a facility for producing liquid helium from a source gas mixture substantially comprising nitrogen and helium. The facility includes a cryogenic purifier including a system for separating the nitrogen from the source gas mixture with a view to producing helium at a temperature lower than the temperature of the source gas. The facility also includes a helium liquefier that subjects the helium to a work cycle including, in series: compressing the helium, cooling and decompressing the compressed helium, and reheating the cooled, decompressed helium. The facility includes a helium transfer pipe connecting an outlet of the purifier to an inlet of the liquefier in order to transfer helium produced by the purifier into the work cycle of the liquefier. The facility is characterized in that the cryogenic purifier includes a decompression system that includes an inlet to be connected to a source of pressurized nitrogen gas. Said system for decompressing the nitrogen gas exchanges heat with the separation system in order to transfer cold from the decompressed nitrogen gas to said separation system.

Facility and method for producing liquid helium

A carbon fuel combustion process, employing an air gas separation unit, a combustion unit operating either with air or with an oxidizer leaner in nitrogen than air, coming from the air gas separation unit, and a unit for compressing and/or purifying the COcoming from the combustion flue gas, wherein the power consumed by the air gas separation unit and/or the flow of oxygen produced by the air gas separation unit and/or the capture of the COcoming from the combustion flue gas are variable over time is presented.

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 Hrich 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 Hflow and in recycling at least the purge and flash gases for feeding the synthesis gas generation stage.

Method for simultaneously producing hydrogen and carbon monoxide

In order to boost production of a product (A) of an existing separation plant (X, ), an additional plant (Y) is integrated with the original plant so as to enable the original plant (X) to produce more of that product (A&plus;B), whilst the additional plant may or may not necessarily itself produce the same product directly. For example, air is separated in a first unit, which is an existing double column distillation plant, to produce an oxygen rich fluid. So as to increase the production of the oxygen rich fluid, a second unit, which is a wash column ( ), is integrated with the first unit. Air ( ) is separated in the single nitrogen wash column ( ) to remove oxygen and gaseous nirogen ( ) is produced at the top of the column. The wash column is fed with liquid nitrogen ( ) from the high pressure column ( ) of an existing air separation unit.

Variable capacity fluid mixture separation apparatus and process

The plant (1) comprises at least three assemblies (10, 11, 12) arranged one beside the other, namely a first assembly (10) comprising a medium-pressure column (2), a second assembly (11) comprising a low-pressure column (3), and a third assembly (12) comprising a heat-exchange line (5). The plant further comprises a liquid pump (6) for making a liquid flow between one of the columns (3) and the vaporizer-condenser (4). Application to the distilling of air using columns with structured interior packing.

Air-distillation plant and corresponding cold box

A plant for separating a gas mixture includes several units having different functions, including a compression unit, a purification unit and a separating unit. Each unit has an attendant cabin which contains monitoring and control systems and, optionally, an analysis system and an electrical distribution system which are necessary for the operation of the respective unit only. The plant may be an apparatus for separating air by cryogenic distillation.
