Virtual Analyser
Virtual Analyser (VA) is a patented software that can calculate and predict parameters without physical measurement, offering a backup solution for analyser failures. It resolves issues with calibration, zero checks, and span checks. VA can accurately monitor critical processes like combustion control, providing safety, efficiency, and reliability.

Virtual Analyser www.technologyedge.biz
What is it Have you ever faced an analyser failure that requires a plant shut down to repair & wished that there was a back up analyser Do you regularly struggle with issues related to calibration gas, zero check, span check etc. If yes, VA (Virtual Analyser) can solve these problems Contact: AKHAQAN@technologyedge.biz
What is it VA (Virtual Analyser) is a Patented Software which can Calculate & Predict the parameter to be measured without physically measuring it How does it work? See the next slide for a summary Or, if you want full technical details, you can look up Patent # 8,768,664 on the internet Contact: AKHAQAN@technologyedge.biz
How it works There are two examples on the next slides which explain how the VA can calculate & predict the parameter to be monitored First example relates to O2 (Oxygen) analyser on a combustion source e.g. Boiler or Reformer Second example related to NOx (Oxides of Nitrogen) analyser for environmental monitoring on a combustion source e.g. a Boiler or Reformer Contact: AKHAQAN@technologyedge.biz
Example-1 of VA Use O2 (Oxygen) Analysers are: Critical for combustion control Safety & efficiency critical Prone to drift, malfunction & frequent calibration VA: Can do the job of an O2 analyser by using inputs on which combustion process is dependent Contact: AKHAQAN@technologyedge.biz
Example-1 of VA Use As you already know, combustion is dependent on following parameters e.g.: Fuel flow rate Air flow rate Combustion temperature Changing these parameters results in changes in the combustion process and residual O2 in the stack The VA uses these inputs and calculates the O2 Contact: AKHAQAN@technologyedge.biz
Example-1 of VA Use At the time of installation, the accuracy of the calculated O2 is verified against a primary standard. Once this is done, the VA can safely & accurately tell the residual O2. Since the VA takes inputs of several parameters to calculate one output, it is vastly reliable & accurate. If you already have a hardware O2 analyser, the VA can be used as a reference to see when & if maintenance of O2 analyser is required. Contact: AKHAQAN@technologyedge.biz
Example-2 of VA Use CEMS (Continuous Emissions Monitoring System) If you maintain a hardware CEMS for NOx, CO, CO2 etc., you already know that it s a struggle to keep it running, see the next slide for details The VA can do the job of a CEMS without all the complications, see the next slide for details The VA when used in environmental compliance is called PEMS (Predictive Emissions Monitoring System) Contact: AKHAQAN@technologyedge.biz

Comparison Hardware Analysers: Are physically installed in the field Actually measure the concentration e.g. NOx Are the primary source of information Virtual Analysers: Are not physically installed in the field Calculate & Predict using other process parameters Are the secondary source of information Contact: AKHAQAN@technologyedge.biz
Uses of VA It can be used for: Environmental regulatory requirements Some hazardous environments which are unsafe for personnel Applications where repair of hardware analysers require a plant shut down Contact: AKHAQAN@technologyedge.biz
Recap VA: Are approved by regulatory agencies e.g. US EPA (United States Environmental Protection Agency) Have lower capital, operating & maintenance cost Are simple & reliable Contact: AKHAQAN@technologyedge.biz
