DURAG GROUP a Multi-dimensional Mathematical Modeling (MdM2) Predictive Emission Monitoring System (PEMS)

The Challenge: Emissions Regulations Governments around the world have implemented or are working on stricter emissions regulations to measure and control the level of emissions by industrial processes. These regulations will require operators to monitor, self-certify and justify emissions of NOX , CO, CO2 , SO2 and unburned hydrocarbons to their country’s environmental agency. Predictive Emission Monitoring Systems, designed in accordance with specifications around the world, including US EPA 40 CFR Part 60 and 40 CFR Part 75, help to maintain emissions compliance and meet data reporting...

Industry Independent Applications PEMS solutions are industry independent and are able to deal with emissions from many different applications. However, fuels should not vary in their calorific values and composition.Typically they a used for gas and oil-fired plants in the utility, petrochemical, chemical and steel sector or other industrial plants or municipal sites. In particular they are tailored for: ► Gas- or liquid-fired emission sources ► Reciprocal Internal Combustion Engines (RICE) ► Regenerative Thermal Oxidizers Suitable Fuel Types include:

The DURAG Predictive Emission Monitoring Systems Solution The DURAG PEMS (dataCEMS) solution uses a Multidimensional Mathematical Modeling (MdM2) technology incorporating empirical models suitable for pollutants such as NOX, CO or O2 as well as first principle knowledge, regression type analysis or formula calculation for CO2 or stack flow to provide a continuous and real-time monitoring of emissions. PEMS define the relationship between a number of characteristic parameters of an emission source and the corresponding emission concentration. By employing historical paired emissions and...

Sensor Validation Methodology (SVM) The heart of dataCEMS is a Sensor Validation Methodology that meets the rigorous requirements of US EPA 40 CFR Part 60, Appendix B to Part 60 – Performance Specifications (PS-16) to continue to operate in the event of sensor failure. This requires a methodology to detect sensor failures or drifts and if possible compensate for those failures which is easily achieved with the dataCEMS Sensor Validation Methodology (SVM). It performs a sensor validation for all input parameters once per minute or once per prediction cycle. One of the main advantages of a...

PEMS Features & Benefits DURAG PEMS solutions: the CAPEX and OPEX Saver! rocess insight P PEMS is a viable diagnostic tool to lower emissions and to improve combustion efficiency. igh performance with low investment H PEMS can accomplish the same accuracy and quality of emissions data of a CEMS with around half of the initial costs. Return on investment (ROI) is usually achieved within a couple of years. A PEMS solution provides reliable emission prediction at all times with a data availability of more than 99 %. operational and maintenance cost Low PEMS solutions reduce manpower...
