Abstract: 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.

Abstract: A leather finishing process in which, in pertinent part, a warm water milling step is added after the base coat is applied to “crust” leather and cured. The warm water contains at least one dye fixation agent including but not limited to about 0.1-2.0% by weight of formic acid. Moreover, the base coat itself is an aqueous base coat containing at least two polymers such as an acrylic salt or a polyurethane salt. Between the polymeric constituents of the base coat, the acid fixation agent, and the use of the warm water milling step after the base coat has been applied and dried, a surprisingly natural feel to the leather is attained without loss of excellent adhesion, wear-resistance and other properties when the leather is completely finished.

Abstract: An acetal or a ketal are prepared by reacting a carbonyl compound and an alcohol in the presence of an acid catalyst and water. Water and alcohol are removed from the reaction mixture in an at least two-stage pervaporation or vapor permeation process using a plurality of membranes. Additional alcohol is fed into a retentate stream of at least one of the two stages. At least one of the plurality of membranes in the two-stage pervaporation or vapor permeation process is different from the other membranes in terms of selectivity behavior in the removal of water and alcohol.

Abstract: A method for scrubbing flue gases of furnaces includes subjecting the flue gases with addition of activated carbon particles to wet scrubbing in a wet scrubbing device. Activated carbon particles are mixed with particles of at least one compound selected from slaked lime and limestone to produce a particle mixture that is introduced into the flue gases upstream of a flue gas heat exchanger that is positioned upstream of the wet scrubbing device.

Abstract: 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.
