<p>An improved flue gas scrubbing apparatus and method are disclosed. The flue gas scrubber comprises a double-pipe or a two-pipe system whereby flue gas enters the system. Scrubbing is accomplished by interaction between the flue gas and base in a pre-injection zone, followed by further reaction in a primary injection zone and passage through a cyclone unit. In preferred embodiments of the invention, it comprises a bypass system by which flue gas is automatically exhausted directly to the atmosphere in case of a system failure. The gas exhausted from the apparatus following scrubbing meets or exceeds international emissions standards.</p> |
