EMISSIONS

EUROPE AIMS TO CUT CARBON LEVELS

The European Union ( EU ) is pursuing new initiatives to become the world leader in low carbon emissions . By 2050 , it aims to reduce greenhouse gas emissions by 80- 95 % below 1990 levels .
Power was identified as a segment where significant reductions can occur through energy efficiency , fossil fuel replacement with renewable energy sources like wind and solar , and European grid infrastructure investments .
Programs like the Medium Combustion Plant ( MCP ) directive affect more than
143,000 medium-sized plants that must now regulate NOx , SO 2 and dust . Combined with tougher Emissions Limit Values ( ELVs ) in the Large Combustion Plants ( LCP ) directive , it plays a large part in European emissions reduction .
Any plant with a thermal input rating exceeding 50 Megawatts falls under the new LCP directive and must apply the Best Available Techniques ( BAT ) provided in the BAT reference ( BREF ) document to reduce emissions to meet the new emissions requirements .
Daily emissions reporting has been added to ensure that the abatement equipment is functioning properly , limiting undetected excursions as well as new start-up and shut-down emissions measurements .
The BREF includes comments on equipment corrosion or fouling that may occur with various techniques .
Adding analyzers for control of the process can help minimize the impact on the plant emissions and performance .
SERVOMEX SOLUTIONS FOR EMISSIONS REDUCTION
Highly accurate measurement equipment will be key for maintaining both compliance and equipment whether the emissions reduction was provided by optimizing the combustion process or adding DeNOx equipment .
Servomex has been instrumental in boiler and turbine optimization with the use of
SERVOTOUGH FluegasExact 2700
our SERVOTOUGH FluegasExact 2700 Zirconia O 2 analyzer , or the SERVOTOUGH Laser 3 Plus Combustion TDL analyzer for CO , O 2 or CO + CH 4 analysis as feedback control monitors .
Post-combustion control of < 3-10mg / Nm 3 of NH 3 Slip from installed DeNOx SCR and / or SNCR equipment will now be
SERVOTOUGH Laser 3 Plus Combustion required as a yearly average or averaged over the sampling period . By using a SERVOTOUGH Laser 3 Plus TDL analyzer , not only will the plant be able to maintain compliance , but the NH 3 signal provides feedback control for dosing , reducing operating costs as well .
