SUMMARY:
Our PEMS – Predictive Emissions Monitoring System, is a state-of-the-art, extremely reliable (over 99% uptime) and significantly cheaper (more than 90%) alternative to the hardware based CEMS – Continuous Emissions Monitoring System.
REGULATORY APPROVALS:
It is approved by US EPA and most international regulatory agencies. Since 1993 PEMS has been installed at hundreds of locations including boilers, reformers & gas turbines in the USA and world over and meets these regulatory standards:
- PS-16, 40 CFR 60
- 40 CFR 75
- Europe (CEN/TS 17198)
- United Kingdom
- Saudi Arabia (Royal Commission)
- Netherlands
- Denmark
- Sweden
- Malaysia
- UAE
PREDICTED POLLUTANTS:
PEMS can accurately predict the environmental emissions e.g. NOx, CO, CO2, SO2 etc. from gas or oil fired boilers, reformers or gas turbines without the need of actual hardware analysers known as CEMS (Continuous Emissions Monitoring System).
PEMS BENEFITS:
- Is more than 50% cheaper in capital installation cost
- Is more than 90% cheaper in operating & maintenance cost
- Is more reliable and has an uptime of over 99%
- It has an accuracy of over 90%
- Doesn’t require calibration, zero or span checks
- The payback time for PEMS software in a petrochemical complex is less than a year
- It takes 4-8 weeks to install PEMS in a Windows PC at a site and no shut down is required.
REPLACEMENT OF EXISTING SYSTEMS:
PEMS has replaced several existing hardware based CEMS on sites where unreliability or high operating cost of their existing CEMS was a constant source of concern. The best part is that in most cases PEMS can use historical data from your existing CEMS installation, whether it is in paper-based reports or digital format in a historian.

If you are thinking about replacing your existing hardware CEMS, then please Contact Us for further details or to schedule a demo install, we maybe able to install PEMS at your site without any capital cost i.e. Free. Our PEMS relies on sophisticated computer algorithms using artificial intelligence and machine learning.
REQUIRED PROCESS INPUTS FOR PEMS:
Depending on availability, some typical process inputs that PEMS uses to work accurately are:
- Fuel flow rate
- Air flow rate
- Ambient weather conditions (Temperature, Humidity etc)
- Combustion or flue gas temperature
- O2 content in flue gas
