Abstract

Exhaust gas purification procedure, in which gaseous contaminants contained in the exhaust gas are separated by reaction with a granular absorption agent inside a fluidized layer, characterized in that the exhaust gas is conducted, with the addition of the granular absorption capable of reacting through separation vessels of conical structure connected in series, of which the cone tips are directed in each case downwards, with corresponding formation of a fluidized layer inside these separation vessels, and because the absorption agent is separated from the exhaust gas leaving the separation vessels, with which an eventual still existing reaction capacity is investigated in relation to the gaseous pollutants to be separated and then, depending on this agent absorption has or does not yet have a sufficient reaction capacity to achieve the desired ef The purification process is returned to the circuit in the conical separation vessels or is discarded as spent.
