What is the most favourable way to use TMT 15® in a flue gas wash water treatment plant?
The previously described combination of neutralisation and TMT 15® dosing is the approved standard method to treat flue gas scrubbing water. The TMT 15® dosage rate to the scrub water is calculated based on the mercury content; under normal operational conditions where the Hg concentration is kept within limits, a TMT 15® addition is not necessary. Whether TMT 15® is required in power plants depends e. g. upon the quality of coal. For ecological and economic reasons the TMT 15® dosage should be optimised. For example an adjustment of the TMT 15® amount is possible by using an on-line mercury analyzer. This combination is mainly of interest for incinerators where the mercury concentration in the waste water varies considerably.
