What is Predictive Emission Monitoring System (PEMS) ?

PEMS?

Predictive Emissions Monitoring Systems (“PEMS”) are 

(a) Software-based data acquisition systems for continuously monitoring emissions by means of plant process data. 

(b) Interfaced with the plant process control system. 

(c) Utilizes inputs from the combustion or pollution control process to determine the emission rates of various pollutants that are regulated. 

(d) The PEMS does not need any gas analyzers.

(e) PEMS is an alternative to Continuous Emissions Monitoring Systems (“CEMS”).

How PEMS differ from CEMS? 

The standard CEMS consists of a sample probe, filter, sample line (umbilical), gas conditioning system, calibration gas system, and a series of gas analyzers as compared to PEMS that consist of only a computer server and audits for portable analyzer
