Stack v6 Software has developed specially for CEMS applications to cover all of requirements of Continuous Stack Gas Data Handling, Monitoring, Reporting and also real time communication with Authority system as part of eco system of CEMS.

It is mainly referred to European Regulatory Framework including EN14181; data validation, unit converstions, calculations and averaging management, also reporting all is well covering requirements.

Stack v6 has developed with experience of past 5 different versions until today from 15 years at least.

Stack v6 Emission Monitoring Platform is also answering nowadays expectations of plants which they have from their Industry 4.0 and IIoT working. So Stack v6 is a good solution to take CEMS monitoring into Industry 4.0 workings.

v6 Emission Monitoring Software is a Platform that open to upgrade for local government requirement of countries, specially Real Time Data connectivity with Authority... Stack v6 supports many methods for that.

WHAT IS EMISSION MONITORING SOFTWARE?

Emission monitoring software is a part of CEMS ecosystem and has working between emission analysers and CEMS users including authority, and results produced by software platform has a great importance because it is directly related to environment and control of pollution degree and while bringing advantages for environment, it advises factories how they can take measure for less pollution for environment. Emission monitoring software works according to government regulations. Most common are EPA - USA and TUV norms of Europe. Emission monitoring is not only data collection and visualisation process. There are many operations like event based data validity, calculations and condition based reporting, also real time connection to the local authority systems.

DATA VALIDATION FOR AN EMISSION MONITORING SYSTEM?

Data validation is the first and one of the most important steps in the emission monitoring evaluation process. Any collected data may not indicate stack gas or dust or flow value due to some reasons or events which influence measurements. Also some events affect only some parameters as independent and this can create problem for further steps of calculations and also there are some requirements of the regulations for these cases including data getting periods and its averages.

CALCULATIONS

Calculations start after data validity and continue until almost the end of all operations. There are two different sides for calculations. One can be said for conversion of units staying with relation of event based data validity. These calculations start from ppm to kg/h values in chain for concentration measurements. There are other calculations for conversion of units for going to flow. And second calculations are related with real time averaging of validated and calculated all parameters in each unit steps and as continuation to calculation, condition based reporting and producing indications related with QAL3 based results can be other calculations within calculation procedures.

CALIBRATION

Calibration or routine checking process is one of the most important topics of CEMS. In the regulation, for long term measurement security, there are some routines called QAL, coded QAL1, QAL2 and QAL3. While QAL1 is related to the manufacturing process of the analyser, QAL2 and QAL3 are related to after commissioning of the CEMS or during operation. QAL2 is performed by an independent accredited laboratory and the results of QAL2 for each parameter are entered into the emission monitoring software, and QAL2 entry is directly related to measurements and also calculations. Let's note QAL2 here, and QAL3 done by CEMS system integrators or CEMS users, operation can be done by manual or automatic using reference gases. QAL3 results are fed into the emission monitoring software to make some calculations depending on previous QAL3 results... There are special reports like CUSUM, EWMA and SHEWHART... QAL3 reports give some comments to the user to perform re-calibration or maintenance of analysers.

REPORTING FOR EMISSON MONITORING

CEMS reporting requirements are completely different from regular data acquisition system reports. Apart from regular data reports between two dates, there are special reports that are event based or according to data validity. Report results determine both the health of CEMS with available data and how exceeded the limit for pollution of environment.

DATA SECURITY FOR EMISSON MONITORING SOFTWARE PLATFORM

Data security is a measure for collected, calculated emissions data. Electronic recording systems are often open to data manipulation. This is the point that it should have a look for an emission monitoring system and end user or authorities should periodically double check from analyser to software for data's correctness. While one point is data accuracy, another point is database security of the emission monitoring software. Software databases must be inaccessible or unalterable. Users and system integrators as well as authorities should take care of this point.

CYBER SECURITY FOR CEMS

Especially in the last 20 years, day by day, cyber security is becoming more and more important for the software working at network. Cyber security is also an important issue for the emission monitoring software because the importance of data results' evaluation or data availability or the requirement of last 5 years' data availability in the system are required to take the highest measures for the emission monitoring platforms. Inaccessible databases, password-protected connection or two-factor authentication and some other software measures can be points that we should take care of.

Supported Analyzers - Instruments :

• ELAN Protocol : It is mainly for Siemens Gas Analyzers such as Ultramat 23, Oxymat and other family members. Support both Rs485 and Ethernet for ELAN
