PCT No. PCT/EP85/00048 Sec. 371 Date Oct. 9, 1986 Sec. 102(e) Date Oct. 9, 1986 PCT Filed Feb. 9, 1985 PCT Pub. No. WO86/04519 PCT Pub. Date Aug. 14, 1986.A process for the removal of pollutants from hot flue gas is disclosed. The gas is cooled and at specified temperatures various acids are condensed out. After a further cooling, heavy metals are removed. Precise control of the quantity of water in the flue gas results in a purification process that is highly efficient. By adjusting the content of free oxygen in the flue gas, the addition of oxidizing agents used to remove sulfur dioxide can be considerably reduced. |
