Which are the basic elements within a PEMS?
In order to deliver a complete PEMS application, it is necessary a PC (typically a Server,
but also a laptop could easily cover all the requirements) hosting IMP On-Line. The PC
must communicate with plant DCS or historian to gather input values needed for
emission estimation and to write predicted values.
The other crucial component of PEMS installations is Inferential Modeling Platform, the
software toolkit that runs the models and provides the estimation of emissions.
Depending on the application, a Data Acquisition System (DAS) may be required: for
typical applications where PEMS are used as a backup of CEMS, the DAS of the existing
Emission Monitoring System (EMS) can be used. ABB has the experience and the knowhow
to properly realize any customized configuration.
