ABSTRACT:
The process for separating toxic organic substances from a dust-containing exhaust gas from a sintering process, particularly a process of sintering iron ore, includes bringing the entire exhaust gas from a sintering conveyor into contact with clays, layer silicate, and diatomaceous earth or mixtures thereof within a gas-solids suspension for a reaction time of from 0.5 to 10 seconds above the dew point at a temperature from 90.degree. to 180.degree. C. and at a velocity from 6 to 200 meters per second. The median particle diameter, d.sub.50, of the solid adsorption agent in the gas-solids suspension is from 5 to 100 micrometers and the mean suspension density of the gas-solids suspension is from 5 to 500 g solids per sm.sup.3 exhaust gas. The dust and other solids are subsequently jointly separated from the gas-solids suspension, and part of the separated solids is again contacted with the exhaust gas from the sintering conveyor. An apparatus for carrying out the process is also described.
