Breath of Fresh air Blowing on the Faroe Islands: Alstom Uses HOK for Waste Gas Cleaning

    COLOGNE, Denmark, COPENHAGEN, Germany, October 16 /PRNewswire/ --
 Activated lignite (HOK) made by RWE Power AG will be used as adsorbent in
 fabric filters for waste gas cleaning in two public refuse incineration
 plants on the Faroe Islands, a part of Denmark. Thanks to this activated
 lignite that is distributed world-wide by RWE's subsidiary Rheinbraun
 Brennstoff GmbH (RBB), a breath of fresh air is now also blowing on the
 archipelago of isles situated in the North Atlantic between Greenland and
 Norway.
     When it comes to equipping power stations and refuse incineration
 plants with waste gas cleaning technologies, a field where Wendt &
 S0rensen, RBB's Scandinavian partner for the distribution of HOK, and
 Alstom Danmark, the leading global plant manufacturer, have been closely
 cooperating ever since the end of the 1990s, the activated lignite from the
 Rhineland is playing a growing role as adsorbent in fabric filters. In
 Denmark alone, Alstom is currently erecting as much as seven new plants
 using HOK for emission reduction.
     "The two new ultra-modern plants that Alstom has built on the Faroe
 Islands," Peter Knudsen of Wendt & S0rensen explains "one in the capital
 Torshavn and the other in Leirvik in the north of the archipelago, have a
 combustion capacity of 2.5 tons of waste per hour in each case. The
 adsorption of mercury and dioxin only requires 800g of activated lignite an
 hour. The plants use the highest product quality offered by RBB: HOK super.
 This ensures not only a low-cost but also significant reduction in these
 emission-relevant pollutants. Process efficiency is more than 99 percent."
 Clean refuse incineration: activated lignite binds mercury and dioxin
     The installed waste gas system works on the dry adsorption principle,
 with the flue gases from refuse incineration being first cooled to an
 optimum temperature for the process before lime and HOK are added. While
 the lime reacts with the acid waste gas components, heavy metals and
 dioxins are separated by the activated lignite.
     The system's high performance--mercury and dioxin are practically
 reduced down to the detection limit--underscores the optimum interplay of
 the technology developed by Alstom and the HOK filter product supplied by
 RBB.
     Activated lignite HOK is produced on the basis of lignite in the
 so-called rotary hearth furnace process and used as an adsorption and
 filtering medium in waste gas cleaning and waste water purification. With
 an annual output capacity of 200,000 tons, RWE Power AG is the world's
 largest producer of activated lignite. The production process that has been
 optimized during many years based on the experience gained ensures the
 production of an inexpensive mass product at a high and constant quality
 level and offers activated lignite in various grain sizes for the most
 varied of applications. Some 500 operators around the world have opted for
 the use of activated lignite in environmental technology.
