Abstract:
A method for removing gaseous contaminants and particulate contaminants (aerosols) from a vapor-saturated gas stream, in which method a gas stream containinga) at least one gaseous contaminant which is soluble in a scrubbing liquid, with or without salt formation, andb) at least one particulate contaminant (aerosol) with a particle size from 0.01 to 10 .mu.m,having a flow rate of at least 0.5 m/s and a temperature from 30.degree. C. to 100.degree. C. when it enters a scrubber column which has an internal surface area of from 50 to 1000 m.sup.2 /m.sup.3, is brought into contact, if initially not being vapor-saturated following prior saturation with vapor, with a scrubbing liquid which has a feed parameter Z to the scrubber column and the temperature of which is lower by at least 2.degree. C. than the temperature of the gas stream, resulting in the formation of a vapor phase, the degree of saturation S of which is greater than 1, and in the removal of the gaseous and particulate contaminants from the gas stream.
