The tower silo system is located on the business premises of Talke, a logistics firm, in Hurth and comprises ten individual silos in all with a capacity of 150 or 200 m3 each. Four different activated carbon types are stored there, with grain sizes extending from granules to super-milled HOK Super.
This rotary hearth furnace coke derived from lignite, which is used in the capture of pollutants and is marketed worldwide by RBB under the brand name "Activated Lignite HOK(R)", has special properties that yield an adsorbent and catalyst which is in demand in numerous environmental fields. Typical applications - besides waste water and drinking water treatment - include waste-gas and waste-air cleaning in refuse incineration and in the steel industry, where HOK is deployed globally as low-cost and highly effective sorbent.
Global use: Refuse incineration, power plants, steel industry
Even in the US, the activated carbon from Rhenish lignite is now helping lower air pollution levels. Besides sulphur dioxide and nitrogen oxides, mercury poses a special challenge for US power plants. Here, too, "Activated Lignite HOK(R)" has proved to be both an outstandingly effective and a low-cost adsorbent.
At RWE Power, activated lignite is produced using an especially designed applied pyrolysis and activation process which creates the special properties. The process, which has been optimized on a basis of decades of experience, guarantees a low-priced bulk product at a constant high quality level in compliance with DIN ISO 9002. With an annual capacity of 200,000 tons, RWE AG is the world's largest producer of activated lignite.
In view of the rising demand from overseas, the Hurth location offers the best prerequisites: there, Talke operates a modern bulk thrower system designed to fill maritime containers. This speeds up packaging and loading on the spot and is an optimal solution for the further transportation of HOK products.
