PROCESS FOR THE PURIFICATION OF EXHAUST GASES CONTAINING OXIDES OF NITROGEN AND SULFUR

摘要

The present invention provides a process for purifying nitrogen-and-sulphur-oxides-containing flue gases from incinerators and industrial production processes by selective catalytic reduction of the nitric oxides with ammonia, subsequent catalytic oxidation of sulphur dioxide with oxygen and reaction of the sulphur trioxide obtained to sulphuric acid.
