PROCESS FOR DENOXIFICATION OF OFF-GASSES FROM ANNEALING AND PICKLING LINES, AND AN ANNEALING AND PICKLING LINE, ESPECIALLY FOR STAINLESS STEEL HOT OR COLD STRIP
Application 236/KOL/2007 published 2007-09-28, filed 2007-02-14
A process for denoxification of off-gases from annealing and pickling lines, providing for the off-gases from the pickling section to be heated and denoxified by selective catalytic reduction (SCR). In order to secure the meeting of lowest NOx values in the off-gas with the lowest possible expenditure, heat is supplied from the off-gases from the annealing furnace (1) to the off-gases from the pickling section (3) before the selective catalytic reduction (9).
