Abstract

The invention relates to a method and apparatus for condensing the abundant water vapour in process exhaust gases and for scrubbing the gas of impurities in gas, solid and liquid droplet form. According to the method, scrubbing liquid is fed into the gas flow in order to cool the gas i.e. to condense the water vapour, in at least two different steps, the later of which occurs as the velocity of the gas is accelerated. After this the gas is subjected to wet scrubbing by routing the gas thus reduced in volume into a scrubbing chamber containing scrubbing liquid, from where the purified gas is discharged after droplet separation into the outside air. The scrubbing liquid is circulated so that some of the liquid is routed from the scrubbing chamber to cooling and solids separation, after which it is recirculated via high-pressure pumps to be fed to the cooling and scrubbing of the gas flow.
