Abstract
The invention relates to a novel and most efficient scrubber for the treatment of flue gases from power generation plants or from chemical plants, in order to absorb objectionable impurities, such as SO , SO , HCl, nitrous oxides, into a water-based solution, in which solids are not substantially precipitated. The novel scrubber comprises: a horizontal chamber, with a basis rectangular vertical cross section, divided along the horizontal axis into a number of compartments by vertically-draining demisters covering the whole vertical cross section; a shallow liquid-collecting sump in each compartment, which can be sloped in any convenient direction; a pump which distributes the liquid from each such sump, at a controlled flow-rate to a series of spray nozzles in the same compartment, generating 3-5 vertical “falling curtains” perpendicularly to the gas flow and covering the whole vertical cross section, while the liquid drops fall back into the sump.
