Emissions
Gas turbine installations and other installations for the
generation of (electric) energy will have to meet strict
environmental demands in the future. It is of vital importance to
the operators of installations to keep their operational costs as
low as possible. The objective for the time to come is to reduce
the emissions, in particular the NOx emissions. Because of the
combination with the near future trade in NOx emission "credits",
it is difficult to gain a good view of the appropriate measures to
be taken to reduce the cost, as a result of the emission reduction,
as much as possible.
In the field of measuring emissions KEMA has had a STERLAB
accreditation for many years and we can advise on optimising your
installations. KEMA can, in particular in the field of NOx
emissions and its trade, be of service to you with the EcoNOx(tm)
product.

Emission trade and measures with EcoNOx™
"The solution for reducing NOx costs"
The rules concerning NOx emissions offer new opportunities to
optimise your operational costs. After all, when your emissions are
lower than the standard you can sell NOx credits. On the other
hand, you are to minimise your costs by taking the most effective
NOx reduction-measures. This is of importance because the emissions
allowed will probably be considerably reduced in the future.
Solution:
Advice about optimising NOx measures is one of KEMA’s core
activities both nationally and internationally. In view of the
future NOx emission, trade the optimisation model
EcoNOx™ has been developed. This model includes,
among other things:- advice on where and when which measure needs to be taken
- ‘what-if’ analyses
- NOx optimisation given a number of preconditions to be
determined in co-operation with the client
- overview of measures, costs and measures per
unit.
On the basis of this model, KEMA can provide crystal clear
pieces of advice, which will help you to save considerable amounts
of money.

Validation of emissions
Emission monitoring plays an important role in
assessing whether the license requirements are met. Additionally,
the monitoring itself and processing the monitoring details also
determine the quality of the environmental annual reports. An
increasing interest is taken in quality control because of, for
example, the (inter)national enforcement of laws. New European laws
also establish requirements concerning the reliability of
monitoring to be met. Major points of interest are: - the latest developments in European law enforcement
- research into the reliability of environmental reports
- assessment of environmental annual reports
- changes in quality concerning the monitoring and registration
of emissions
- the translation of the contents of new international standards
into practice.
Introduction Law Enforcement
The concept of uncertainty is not used univocally in current
legislation. Many companies and upholders have to deal with, for
example, the BEES, Bla and NeR [Dutch quality standards].
Furthermore, there will be new European Standards and a future
system for NOx emission trade. In December 2001 the new European
Standard for Large Incineration Plants was put into effect. This
Standard contains requirements concerning emission monitoring:
continuous automated monitoring of a number of air-polluting
components in the flue gases of waste incineration plants. This is
not something new. The fact that the uncertainty of the monitoring
values obtained in this way shall not exceed a certain limit
determined is though.
‘At the daily emission limit value level, the values of
the 95% confidence intervals of a single measured result shall not
exceed the following percentages of the emission limit values: CO:
10%, SO2: 20%, NOx: 20%, dust: 40%, TOC: 30% and HCl:
40%.’
As for testing whether the automated company monitoring
equipment meets the required uncertainty demand the European
standards are referred to. In 2000 a division of the European
Standard for Large Incineration Plants was started (Standard
88/609/EEC). This revision now only still needs the European
Parliament’s approval. In this revised Standard emission limit
value levels were mentioned and requirements for these monitoring
values were established for the 95% confidence interval for
continuous emission monitoring (SO2: 20%, NOx: 20%, dust: 30%).
Quality Guarantee StandardsThe European standard ‘Emissions of Stationary
Sources: Quality Guarantee of Automated Monitoring Systems’
0-NEN-EN 14181, is examined here. This standard was drawn up to
check whether the uncertainty requirements of monitoring values of
continuous automated systems could be met. Points of interest
are: - basic statistics
- preselection of equipment
- installation and calibration
- quality guarantee and control
- annual control and testing.

Emission monitoring: "Save money with reliable measurements"
Your situation:
Power plants and a growing number of industries who’s power generation is based on combined cycles request KEMA to perform emission measurements. For instance, to test whether the limits - which are continuously lowered - are not exceeded. Or to obtain a permit to operate. The authorities are setting high demands for the exactness of the measurements concerning the environment. Nowadays the emission of CO2 and NOx are getting financial values and become tradable. Accurate environmental measurements can earn you money. KEMA can help you to achieve this with its long-term experience of monitoring flue, process and exhaust fumes. Our team of experienced specialists works with calibrated equipment. KEMA also offers condition monitoring and guarantees measurements, and advises you how to optimize your processes. We will translate this into financial benefits.
Our approach:
KEMA has mobile emission laboratories equipped with advanced analysis instruments to detect all relevant components in flue, process and exhaust fumes. For this purpose we use certified calibration gases. We also measure gas velocity and flue gas flows. All instruments are calibrated. KEMA’s environmental emission department has accreditation at STERLAB for monitoring on site and is ISO 9001 certified. With these monitoring data we support your permit-application, calibrate and check your own equipment, calculate your annual emission, and advise on process-optimization. We organize courses and training’s.
Your benefits:
Certainty that the obligatory emission limits are met:- when trading your emission rights you know exactly what you are talking about;
- your production processes are optimized;
- insight into the efficiency and emissions of your operations;
- assurance that the equipment runs as expected by means of guarantee measurements;
The environmental performance of your operations will improve.
