Oxygen enrichment boosts Claus plant capacity

Article Abstract:

Linde Technische Gase GmbH of Hollriegelskreuth, Germany, has developed a process of increasing the throughput of Claus plants. The process, which boosts the capacity of an exisiting plant by enriching the feed air with oxygen, is aimed at addressing the problem of large inventories of hydrogen sulfide in refineries due to fuel desulfurization initiatives. The procedure, which requires a minor investment on the part of the operator, is being tested at two Claus plants in Germany and France.

Falling-film microreactor facilitates hazardous reactions

Article Abstract:

The Institut fur Mikrotechnik Mainz of Germany has developed a safe means of direct fluorination of aromatic compounds using concentrated elemental fluorine. The technique, whose small size but high efficiency makes it viable for industrial-scale manufacture, uses a falling-film microreactor composed of a reaction plate combined with a micro heat exchanger. The microreactor's yield for ortho-, meta-, and para-fluorotoluene has been measured at 20%, a big improvement from the 5% yield from conventional bubble-colulmn reactors.

Wet CO2-scrubbing lowers the cost of hydrogen production

Article Abstract:

Caloric Anlagenbau is using a wet-scrub process in removing carbon dioxide during the production of hydrogen, resulting in an H2 yield of 99%. The investment costs for the wet-scrub process is 25% lower than that for pressure-swing adsorption since a smaller steam reformer and lesser feed are required. Hydrogen is produced by the wet-scrub process through the steam-reforming of natural gas which followed by a two-step carbon monoxide shift reaction. It produces a mixture of about 75% H2 and 23% CO2 at 16 bars.
