Continuous Emission Monitoring Systems & Data Acquisition System

What is Continuous Emission Monitoring Systems (AML-CEMDAS)?

AML-CEMDAS is designed to monitor and report requirements in an easy, reliable, and cost-effective way.

Continuous Emission Monitoring System (CEMDAS) solution is proven to meet complex regulations worldwide, including Swiss OAPC, US EPA part 60/75, EN 17255, KSA RCER and PME, Alberta CEMS code, and Canadian 1/EPS/PG7. AML-CEMDAS is a powerful and robust software application package that can store, analyze, visualize and report environmental data from various sources. The main goal of Continuous Emission Monitoring System (CEMDAS) is to demonstrate environmental regulatory compliance with various industrial sources of air pollutants. The primary pollutants measured by a Continuous Emission Monitoring System include carbon monoxide (CO), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), hydrogen chloride (HCI), volatile organic compounds (VOCs), ozone (O3) and heavy metals such as mercury (Hg).

CEMDAS can also be set up to monitor other parameters of a site’s flue gas effluent in order to reveal insights into its day-to-day functioning. These include such variables as the airflow in the sample. These data can help to produce readings of contamination concentration on a mass per hour basis. 

AML-CEMDAS helps your company manage environmental audit risks, save time with maintaining the CEMS analyzers and preparing regulatory reports, and significantly assist with environmental accountability and compliance as part of the corporate sustainability policies and procedures.


Why is continuous emissions monitoring so important?

Monitoring emissions is nowadays a hot topic through the energy transition. In response to the call for climate change activism among government regulations, the cost of CO2 emissions is going to increase, at least in the European Union, which is decreasing the number of free allowances and increasing the tax on CO2 emissions. The European Union is charged with reducing emissions by 55% by 2030. The main goal is to demonstrate environmental regulatory compliance with various industrial sources of air pollutants to avoid high penalties and fines.

There is a reason that there are government regulations about the limit of emissions. On the one hand, a high concentration of contaminants like CO2 has a negative impact on the air quality levels in the vicinity of the site. On the other hand, specific pollutants like methane and CO2 are particularly damaging to the plant. Collectively known as greenhouse gases (GHGs), these contaminants help to trap heat in the environment and contribute to global warming. That’s the reason why the emissions must reduce by 55% by 2030.

Generally speaking the main pollutants measured by CEMS include carbon monoxide (CO), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), hydrogen chloride (HCI), particulate matter (PM), volatile organic compounds (VOC’s), ozone (O3) and heavy metals such as mercury (Hg).

Challenges managing limits on emissions

Air pollution is one of the biggest problems faced today. To meet the requirements and standards, it’s essential to measure the emissions. But how do you know what your smokestack is releasing into the atmosphere? That is a big challenge for many companies. Also, there are other challenges like: 
  • – Ever-changing regulatory standards
  • – Technology options
  • – A significant percentage of Continuous Emission Monitoring Systems (CEMDAS) rely on obsolete or discontinued systems.
  • – The EPA mandated 95% availability means systems can only be down 18 days per year.
  • – Emission estimating and reporting
  • – Low uptime of analyzers (Below 90%)
  • – Trust of CEMS analyzer data (reliability)
These regulations and challenges are often complex and hard to navigate, and companies that fail to meet them can face severe penalties and fines.
