A PUSH FOR CLEANER INDUSTRIAL PRODUCTION
Cementa AB Sweden achieves 80-85%
NOx emission reductions with SNCR in two
installations, Skövde and Slite
3
• Nitrogen oxide emissions less than 200mg/Nm
• Stable functioning over a prolonger period
• Total cost of NOx abatement: 250 €/t of NOx.

Reductions in nitrogen oxide foreseen
Italcementi Group, 2008
Progressive Member States have already acted to protect their citizens by imposing stricter emissions
standards for nitrogen oxides through establishing general binding rules. There are cement
installations successfully operating with emissions below 200 mg/Nm 3 in Italy and Sweden.
Germany has set 200 mg/Nm 3 for new and substantially changed co-incineration cement kilns
after 2012 as well as for existing kilns when combustion is based on 100% waste.

Cementeria di Monselice cuts nitrogen oxide
emissions with SCR
• Nitrogen oxide emissions less than 200mg/
Nm 3
• Nitrogen oxide removal efficiencies of 97%
• SCR is a “cost effective multi-pollutant control
strategy”

The application of SCR to NOx emission
reduction in the cement industry has been
successfully tested in Austria, Italy, Sweden
and Germany.
Results of a successful pilot plant trails in
Kirchdorf,
Upper Austria resulted in NOx emission levels
of 100-200 mg/Nm 3 .

• NOx emissions reduced to 200 mg/Nm
• 90% NOx reduction rates achieved
• additional reductions in ammonia
• Cost effective and economical
