A method and reactor for performing exothermic reactions with parallel operated catalyst modules arranged in stacked order within a pressure shell and adapted to axial flow of process gas through one or more catalyst layers and at least one catalyst layer cooled by an intrabed heat exchanger.

Method and reactor for performing exothermic reactions

In a converter for the catalytic oxidation of SOto SOin a sulfuric acid plant, which comprises a boiler section for the cooling of process gas between catalytic layers (beds), one or more water tube boilers (inter-bed boilers) having horizontal or slightly sloped tubes are used to cool the process gas between the catalytic layers (beds) in the converter. Each water tube boiler is provided with a process gas side bypass to control the temperature to the downstream catalyst layer.
