Reasons to Get the Best Predictive Emission Monitoring System

 The typical Predictive Emission Monitoring System (otherwise abbreviated as PEMS) is a software- based data acquisition system used to continuously monitor emissions from various industrial and commercial pursuits and projects. It relies on plant process data to achieve its goals, including.

1. Regulating Pollutant Emissions

As a result, there are interfaces between the plant process control system and the PEMS. It uses inputs from the pollution or combustion process to ensure that the pollutant emissions are well regulated. You should also keep in mind that these systems do not need gas analyzers to function as required.

2. Comply with Emissions Legislations

Predictive Emission Monitoring Systems use historic paired emissions and certain process data (environmental conditions, boiler and turbine settings, variables from flue gas abatement systems and data on temperature, pressure, flow, fuel composition and load) to generate a model. The model is used to determine the actual emissions from the plant for compliance purposes.

3. Alternative to CEMS

At other times, the PEMS may be used as an appropriate alternative to CEMS (Continuous Emissions Monitoring Systems) in oil- or gas fired plants such as heaters, boilers and turbines. This is especially in the monitoring of components like VOC, HC, H2S, NH3, CO2, O2, CO, SO2 and NOx.

4. Environmental Protection

Environmental protection agencies such as the US EPA (the agency that enforces environmental legislation in the United States) evaluate empirical and parametric PEMS. The evaluation is based on tests for positive results with regards to corresponding programs outlined to ensure that the PEMS meet certain industry requirements. Therefore, Predictive Emission Monitoring Systems are useful in ensuring that operations do not lead to environmental degradation.

5. Quality Assurance

Special emphasis is placed on the quality assurance of industrial processes. The PEMS is used in multiple plant sites to ensure that the operations adhere to quality assurance standards, in the United States, the Middle East and in Europe.

6. Reduce Operational Costs

Replacing outdated CEMS with predictive monitoring systems reduces operational costs. This is as a result of low capital expenditures, maintenance and operational costs. In fact, PEMS can be used to provide more accurate results and quality emissions data in comparison to CEMS.

Overall, the best Predictive Emission Monitoring System should comply with current emissions regulations and other minimum requirements in the industry. It should also function suitable in the plants where it is used. To ensure this happens, plant managers should select suitable process and monitoring parameters, test the PEMS and use the findings to determine whether the system will function properly.
