With a total filter surface area of 93 square metres each they range among the largest FGD belt filters in the world. For many years now FL has been relying on FGD gypsum filter cloths in Vacubelt belts from GKD. This is why in 2008 the two new blocks in Neurath were specifically equipped with the doublelayered Vacubelt 2025 filter belt.

These side products are formed in the flue-gas desulphurization plants (FGD) of power stations which are fired with fossil fuels. In Lünen, Remondis transforms these FGD gypsums into high-quality additives and binders which are then supplied to the gypsum industry under the trade name of "RADDiBIN" as raw material for different applications.

According to statistics, in China the wet FGD gypsum production was 35 million tons in 2008, doubling the total for 2007 [31]. If the average Hg concentration in FGD gypsum is taken to be 962 ppb, it follows that the Hg mobilization potential for FGD gypsum in China was about 33.7 tons in 2008.

Flue-gas desulphurisation (FGD) systems have been used to limit the emissions of sulphur dioxide (SO2) from coal-fired power plants since the late 1960s. The first large scale systems were installed in North America, Europe and Japan, due to the growing concern about acid rain in these areas of the world. Acid rain can have v…

As we know, coal is the dominant energy in Chinese energy mix. Almost all of the coal-fired power plants are required to equip desulfurization facility to remove SO 2 in the flue gas, as illustrated in Fig. 1.The most popular desulfurization technology is wet-FGD using limestone, with the product called FGD-gypsum, which main content is CaSO 4. ...
