Process for reducing the concentration of polyhalogenated aromatic compounds or polynuclear aromatic hydrocarbons in flue gas

摘要

The concentration of polyhalogenated aromatic compounds or polynuclear aromatic hydrocarbons in a flue gas is reduced in a process wherein the flue gas is contacted with a scrubbing liquor containing an oil and optionally water, wherein the oil and water together constitute at least 60 percent of the total weight of the scrubbing liquor and at least 50 weight percent of the oil contained in the scrubbing liquor is a vegetable oil.
