Abstract

Procedure to avoid the formation of condensate in tubular pipes of catalysis installations in which SO2-containing gases are catalytically transformed into SO3, in which the SO3 content of the gases leaving a catalyst support grid is absorbed by acid sulfuric in an intermediate absorption stage and the gases leaving the intermediate absorption stage, before entering the next catalyst support grid, are heated in a heating device to the operating temperature of the next support grid catalyst, characterized; because the tubular line between the outlet from the intermediate absorption apparatus and the heating device is structured in the form of a double-jacket line and hot gases are conducted through the double jacket and the temperature of the inner jacket is maintained above the dew point of gases conducted through the tubular line.
