Abstract

A process for the treatment of offgas from sintering and pelletizing plants, in which dry additive is added to the offgas from a sintering or pelletizing plant upstream of a fabric filter (3), in particular in an offgas channel (2), and the additive is subsequently removed from the offgas by the fabric filter (3). The process is characterized in that the additive contains sodium hydrogencarbonate NaHCOas reagent and is at least partly recirculated into the offgas stream, in particular into the offgas channel (2), upstream of the fabric filter (3), is disclosed. This enables gas conditioning (cooling) as is necessary for a lime-containing reagent 1 to be avoided.
