Abstract Information :
To grant highest availability of Continuous Emission Monitoring Systems (CEMS) while keeping operational
expenditures (OPEX) to a minimum becomes of more importance than was ever known in the past. An
analysis of the "Total Cost of Ownership" reveals approaches to optimizing a CEMS OPEX. Both regulatory
requirements, with their quality assurance and control requirements, as well as routine inspections and
maintenance need to be taken into account. The asset management concept 'Advance Operation' offers
solutions based on the collected requirements.
Reducing OPEX includes fully automated calibrations. This also includes the automated documentation of all calibration relevant data like set-points, drifts etc. Technologies are preferred to do all calibrations without test gases. For this reason the application of reference materials like gas filled cells or gas filters becomes more important. Reducing the time frames conducting calibrations in order to improve their availability is an integral part of an entire solution package, which is of special importance for multi-component CEMS. Expenditures for service are incurred in case of malfunctions and failures of CEMS. The CEMS must be repaired on an urgent basis. Usually only the direct repair costs are determined. Off-times of the measurement, expenses for coordination for the repair, etc. are often not recorded here. The solution is optimized design of a CEMS with integrated self-monitoring of all relevant inputs and predictive maintenance to warn the operator before a failure occurs.
Many data of the devices participating in Continuous Emission Monitoring have to be gathered and evaluated to set-up a self-monitoring and predictive CEMS. This is usually done at high cost by regular onsite inspections. Standard office Ethernet along with the PC application AnalyzeIT Explorer now helps in the process of gathering the necessary data, channeling it and making it available to the maintenance team in a targeted manner. However, this goes far beyond the Process Control Technology needed to operate and maintain a plant. Modern asset management requires more in-depth information on the condition of the CEMS and the possibility to completely remote-control CEMS via an Ethernet connection. Many maintenance tasks such as configuration, validation, calibration and software updates can be performed from AnalyzeIT Explorer for each networked CEMS.
All these measures support plant operators to make asset management more affordable while increasing the availability of their CEMS and lowering OPEX.
