    • In the method of scrubbing flue gases, the flue gases are wet-scrubbed in the presence of activated carbon. The activated carbon is separated from a suspension resulting from wet scrubbing. The activated carbon is then divided into a first and a second portion, and the first portion is thermally desorbed. The first portion of the activated carbon is returned to the second portion of the activated carbon. The first and second portions of the activated carbon are recirculated to the wet scrubbing step. The device for scrubbing flue gases includes a flue gas desulfurization scrubber with a flue gas inlet line, a flue gas outlet line, and an adsorption medium line. A treatment device for treating a suspension formed in the flue gas desulfurization scrubber is provided. A thermal desorption device for the activated carbon is provided. The treatment device includes a separator for separating solid material from the suspension. The treatment device further includes a flotation device having a gypsum outlet and an activated carbon outlet. The activated carbon outlet is connected to the adsorption medium line and to the thermal desorption device.

    • A method of removing mercury from flue gases from combustion plants, such as for example power plants or waste incineration plants, is achieved in which mercury-containing flue gases are brought into contact with an adsorption reagent either directly or indirectly by being contained in an absorption reagent, whereby mercury is substantially adsorbed by the adsorption reagent during this contact. After adsorption has occurred the adsorption reagent is separated from the flue gases and subsequently from the absorption reagent and added to an aqueous solution containing an oxidizing agent, whereby the adsorbed mercury dissolves as Hg2+. The Hg2+-containing solution is subsequently separated from the adsorption agent and the Hg2+ then is removed from the solution. This method enables the mercury to be removed from flue gas in a simple and economical manner.
    • 实现了从诸如发电厂或垃圾焚化厂等燃烧装置的烟道气中除去汞的方法,其中含汞烟道气通过吸收直接或间接地与吸附剂接触, 试剂,由此在该接触期间汞被吸附剂基本吸附。 吸附发生后,吸附剂与烟气分离,随后从吸收剂中分离,并加入到含有氧化剂的水溶液中,吸附的汞溶解成Hg2 +。 随后将Hg2 +溶液与吸附剂分离,然后从溶液中除去Hg2 +。 该方法能够以简单和经济的方式从烟道气中除去汞。
