Plant upgrading to fulfil new EU directive - in operation 2003
General aims:
The first ADIOX
®
full-scale test.
Also, to obtain an initial reduction of
dioxin emissions by reasonably
simple means. After upgrading the
plant to meet the 0.1 ng/Nm
3
dioxin
Active
emission limit, the aim is to mini-
carbon
mise the memory effect (desorption

of dioxin).
Description:
In September 2001, the very first ADIOX
®
-installation in a flue gas cleaning system was made at KVVT
Thisted in Denmark.
A wet type flue gas cleaning system had been installed by Götaverken Miljö in 1992. The 2002/2003
upgrade, to fulfil the latest EU emissions directive, was also designed by Götaverken Miljö.
The Thisted plant incinerates some 6.5 tons per hour and produces some 110GWh of heat and 21GWh of
electricity annually.
Initially, the plant operations, with ADIOX
®
installed, had reasonably high dioxin inlet concentrations
(5-10 ng/Nm
3)
. The performance during plant start-up (low gas flow) showed extremely good results.
During the ongoing full-load operation period of over a year, the dioxin reduction level remained at
approximately 70%.
Following installation of the new bag house filter, the dioxin concentration into the scrubber system is
well below 0.1 ng/Nm
3
. The aim of the ADIOX
®
packing is to absorb the dioxin that was previously
desorbed by the plastic material in the system - the memory effect.
