Device for the catalytic reaction of a gas mixture containing H2S and SO2 by the Claus process

摘要

The apparatus comprises a container which has a central cooling chamber and an annular chamber which surrounds the cooling chamber and contains catalyst. The gas mixture to be reacted contains H2S and SO2 enters the annular chamber and first flows through the catalyst. The cooling chamber contains at least one coolant line and is provided with a passage for gas mixture coming from the annular chamber and with a gas outlet.
