Further benefits of glosfume
®
filters in dry
scrubbing applications
Of course, there are no filter bags to catch fire.
Removing HCl at temperatures above 400°C prevents reformation of dioxins.
A certain amount of the sodium bicarbonate converts to a gas, which means that there is less
material to go to land-fill. Thismakes sodiumbicarbonate preferable to lime where environmentally
friendly disposal is important.
Using
glosfume
®
high-temperature ceramic filters and dry scrubbing with sodium bicarbonate
and/or activated carbon achieves outstanding emission results.
The following typical figures show clearly how our high-temperature ceramic filter systems meet
current and probable future regulations. All the results are around 90% lower than the official
emission limits.
