摘要

Variations in a procedure to separate contaminants from a gas fumes, especially from flue gas containing Sulfur dioxide.Consistent: a single provision in the Smoke gas Cooling below the Dew Point of the outside Air by countercurrent, and washing the gas fumes; introduce the gas fumes in a First Treatment areaA First Absorption liquid for gas purification so that 5 / 6 of the gas Stream Smoke received the addition of the first liquid and 1 / 6 of the second Fluid Absorption during the switching cycle of one to four hours; Clean installation,Introducing a Second Liquid absorption in a Second area of the Smoke gas treatment; split the gas fumes, passing through the Interchange, divided into two Currents conducted in parallel.The first is made through the first and the second Treatment area by the second Treatment area; and driving in the same direction Flow of condensate from gas smoke and Liquid absorption. It is used to remove pollutants from the flue gas.
