Continuous Emission Monitoring System (CEMS)
Continuous Emission Monitoring Systems (CEMS) are methods used to monitor emissions from industrial site smokestacks, including refineries, power stations, and manufacturing plants, where fuel source combustion occurs.
Emission monitoring systems are designed to measure fuel flow, dust, and the concentrations of air pollutants like SO2, NOx, CO, CO2, THC, and O2, complying with the relevant regulations for the emission source.
Besides their basic function of enhancing site safety, CEMS systems also ensure that facilities comply with legal obligations. There are various global standards and methods for environmental monitoring. All combustion plants are required to monitor and analyze their gas flue effluents to ensure compliance with the established maximum thresholds for specific contaminants.
CEMS are essential for plants, refineries, power stations, and other industrial sites where fuel combustion is routine. They serve multiple purposes, including providing crucial data on dust levels and concentrations of air pollutants like SO2, NOx, CO, CO2, THC, and O2. This ensures that these sites are safe for human presence and do not present a fire hazard, which is particularly relevant in facilities where open flames are an integral part of operations.
What is Dirk Horst’s expert take on Continuous Emission Monitoring Systems?
We asked process industry veteran and expert in the field of Process Gas Chromatographs (PGC) and Continuous Emission Monitoring Systems Dirk Horst to do the impossible: To summarize CEMS on three sheets of paper:
Short Introduction to CEMS
A special field of the applied analytical instrumentation, not limited to the oil and gas industry are the analyzer systems, the so called “CEMS”, that are part of systems that need to comply with stringent mandatory measurement requirements and data logging for the purpose of environmental pollution control.
They specifically deviate from the normally operated process analyzer systems by the fact that the validation is not limited to the analyzer system as it also includes the validation of the applied sampling system.
Main reasons why these CEMS are installed
The main reasons why Continuous Emission Monitoring Systems are installed are:
- Regulatory compliance
- Monitoring of plant performance
- Calculation of the emissions
- Assessments of impact to the environment.
Environmental Protection Agency (EPA) regulations
Most of the worldwide applied regulations are based on the original promulgated Environmental Protection Agency (EPA) regulations.
The mission of EPA is to protect human health and the environment and ensures that people are protected from significant risks where they live, learn and work. National efforts to reduce environmental risk are based on the best available scientific information while Federal laws for protecting human health and the environment are enforced fairly and effectively.
Following the EPA, now many countries have developed Continuous Emission Monitoring Approval schemes.
European emission regulations
In Europe, several specific directives are related to industrial emissions including the “Integrated Pollution Prevention and Control” (IPPC) Directive have been brought together into a single document as a legislative Directive. In 2017 the European Commission has issued the “MRR Guidance” document for supporting the implementation of Commission Regulation (EU) on the monitoring and reporting of greenhouse gas emissions.
In the UK BS EN 14181 covers stationary source emissions and quality assurance of Automated Measuring Systems.
The owner or operator of a production unit, as under a legally regulated Program, MUST install Continuous Emission Monitoring System (CEMS) on the unit unless otherwise specified in the regulation.
Plant operators are required to obtain an environmental permit from authorities in EU countries.
The EPA regulates emissions under the “Code for Federal Regulations” (CFR) that consists of more than 50 volumes, known as Titles. Title 40 of the CFR (40 CFR) lists all environmental regulations with part 60 & 75 covering a wide variety of combustion sources from commercial, institutional, industrial and utility boilers through to incinerators, refineries and combustion turbines.
The Emission Measurement Centre (EMC) of the EPA has produced hundreds of methods of measuring air pollutants emitted from the entire spectrum of industrial processes causing air pollution.
The EMC is also a bridge between the regulators and the regulated community in providing technical expertise and guidance. The EMC is the focal point for planning and conducting field test programs.
To whom do the requirements apply?
Depending on the amount of energy used by an operating company using different fuels like coal, natural gas or other types resulting in emission of polluting gases and / or effluents, there are specific limits set for each pollutant and the maximum integrated amount during a certain time period.
Where does a CEMS consist of?
All equipment that is necessary for the accurate determination of the integrated amount of a gas or particulate matter emission or disposal like wastewater systems into the environment, making use of online analyzer measurements systems.
The obtained measurement data is used to determine the integrated amount of pollution making use of data processors to produce a.o. standardized results in the correct units of emission and records historical trends.
The Continuous Emission Monitoring Systems or CEMS for Measuring and Monitoring is divided into the “Automated Measuring System” (AMS) and a system to calculate and evaluate the emissions, the Automatic Evaluation System (AES).
As an alternative for the traditional CEMS, also Predictive Emission Monitoring Systems (PEMS) may be applied. These, not hardware-based systems, make use of dedicated algorithms, that are based on the input of specific process parameters to determine emissions.
Continuous Emission Monitoring Systems applications and measurements
The specification of the CEM system will depend on not only the type of process, but also on the type of pollutant gases that are required to be measured. Since there are many applications for continuous emission monitors, covering a wide range of industries, there are many different analyzers.
The ranges of each of the to be measured components or particulate to be monitored are all specified.
All analyzers that are part of a Continuous Emission Monitoring System should be certified by the “Monitoring Certification Scheme”, short MCERTS. as being approved by the government after having successfully passed a type of approval test.
All approved analyzers, supplied by several companies, are listed on the website from MCERTS.
Relative Accuracy Test Audit (RATA)
After the Operational Test Period for certification a Relative Accuracy (RATA) and Bias Test are performed. This is essentially a comparison of the facility CEMS data (concentrations and emissions) to an “Accepted Reference Method” short RM, during a specified time period.
Performance certification tests for CEM after installation:
- 7-day calibration error test for each monitor,
- Linearity check for each pollutant concentration monitor (introduction of 3 concentrations),
- Relative Accuracy Test Audit (RATA) for each monitor,
- Bias test for each SO2 pollutant concentration monitor, flow monitor, and the NOx CEM system,
- Cycle time test for each pollutant concentration monitor.
What are the essential parts of Continuous Emission Monitoring Systems?
- Sample probes, • Sample lines • Sample pumps,
- Sample conditioning equipment like heaters, condensers, gas Dilution equipment for Dew Point lowering !
- Pollutant concentration monitors e.g., SO2 or NOx monitors,
- Diluent gas monitors to measure % O2 or % CO2 ,
- Stack gas Volumetric Flow rate monitors,
- Data loggers and Programmable Logic Controllers – PLC’s,
- Data Handling System for the CEM system for recording and performance monitoring of all measurements.
Types of CEMS sampling techniques
EPA has developed specific Emission Sampling Methods for many applications that can be divided into ‘Extractive’ and ‘In situ’ systems.
Dilution Extractive systems are applied to be able to measure the flue gas pollutant concentrations on a wet basis by diluting the sample vapor with dry clean air that is introduced at the specially designed sample probe. Important additional effect is that the Dew Point of the vapor is reduced which lowers the chance of condensation in the sample transport lines.
Critical Orifices are applied within the sample probe to establish a fixed Dilution Ratio and stack gases pressure are almost atmospheric and so pumps are required to extract the sample.
CEMS makes use of umbilical sample bundles consisting of 4 -6 separate teflon lines having specific properties to make it suitable for the job. One line for the sample, the second for calibration or probe purging, the third for the dilution air, the fourth one for monitoring and spare lines.
Heated bundles are only applied for very low ambient temperature conditions and small dilution ratios.
Two main types of extractive systems: The Dry-Cold and the Hot-Wet sampling systems
There are two main types of extractive systems: The ‘Dry-Cold’ and the ‘Hot-Wet’ sampling systems, see figure.
The “Dry-Cold” type of sampling requires a stack sample probe with heated sample line to a gas pre-conditioning panel. Part of the sample preparation prior to entering the analyzer is to remove the water vapor by rapidly chilling the sample. This sample conditioning system requires a significant amount of maintenance to ensure all sample preparation components are operating correctly but the major drawback with this type of CEMS is that a significant percentage of any soluble gas, such as NO2, SO2 and to a lesser extent NO may be removed along with the water vapor.
‘Hot /Wet’ Continuous Emission Monitoring Systems are applied because some gas constituents can only be measured in a hot/wet state like HCl, Ammonia, or HF as they are totally soluble in water and will scrub out if chilled. These hot extractive systems also require a stack sample probe with heated sample line to the analyzer.
The sample gas to the analyzer needs to be maintained at a temperature above the sample dew point to prevent water formation because water formation at the gas analyzer will cause severe cross sensitivity issues with other measured gases, plus expensive analyzer maintenance.
Measuring and Auxiliary Equipment for CEMS
It would go too far to discuss here all issues that are involved with CEMS. Additional auxiliary equipment is necessary to optimize the sample conditions mainly to prevent condensation like Coolers, Moisture Monitors, the types of applied analyzers like Spectrometers, the Ultra-Sonic and Thermal Mass flow stack gas flowmeters and the Data Handling System for the necessary calculations and evaluation of the emitted mass amount of the polluting components.
Dirk’s first professional study was in Electronics which was successfully followed by a dedicated study in instrumentation and obtained several other specified certifications during his long a career in the Oil and Gas industry.
Dirk has more than 34 years of experience in QMI, including the Dutch Oil Company N.A.M. (owned by Royal Dutch Shell), Shell Global Solutions in Amsterdam, Shell Head Office in Hague, Reliance Petroleum Refinery Ltd. in India, Nigeria LNG. and Shell in Sakhalin, Russia.
Dirk is currently working as Freelance Trainer to transfer his long-term experience to young engineers and technicians joining the world of instrumentation.

Analytical Solutions and Products employees are trained by Tony Waters and are very familiar with his and the work of Dirk Horst.
Types of emission gas analyzers
Ultraviolet (UV)-based analyzers
The UV-based measurements are chosen for Continuous Emission Monitoring Systems because they are unaffected by interference from water (H2O) and carbon dioxide (CO2). They also provide a wide dynamic range for some measurements. There is no need for sample drying, which greatly simplifies sample handling and integrity. High-intensity line source lamps emit a fixed wavelength for measurement stability, and emit low total power, which removes the potential for sample photolysis.
FTIR spectrometer
Fourier Transform Infrared spectroscopy (FTIR), compared to other IR techniques, can measure many components in real-time due to the use of an interferometer that allows the collection of a broad range of wavelengths. FTIR spectrometers are undeniably one of the most reliable technologies due to its sensitivity and capability to recognize extremely low concentrations of gases. FTIR gas analyzers can measure from low ppm levels up to vol-%.
Flame Ionization Detectors (FID) analyzers
The Flame-ionization Detector (FID) measures the total organic carbon (TOC) contained in emission gas samples. The most sensitive and widely used technology for the measurement of Total hydrocarbons (THC), Non-methanic Hydrocarbons (NmHC), and Methane (CH4).
Zirconia oxygen analyzers
Zirconium oxide measurements are used in CEMS because they are a trusted, industry-proven sensing technology for fast and accurate oxygen analysis in a wide range of applications, particularly combustion processes. Capable of measuring oxygen at percentage or parts-per-million levels, zirconium oxide sensors can be used in both extractive and insitu probe instruments, providing solutions for a wide range of industries.
Range of CEMS applications
Emission Compliance
Reliable, accurate emission monitoring with a CEMS is essential to ensure processes comply with environmental regulations. This requires operators to properly install suitable measurement equipment that meets all regulatory criteria.
Industrial boilers
Boilers are required to provide the power and steam needed for many industrial processes. Efficient burner Boilers are required to provide the power and steam needed for many industrial processes. Efficient burner control ensures reduced fuel costs and lower emissions, and depends upon optimizing the combustion reaction between oxygen (from air) and the fuel used. An ideal ratio between the two ensures safe and efficient operation with minimal emissions.
Hydrocarbon processing emission compliance
Boilers are required to provide the power and steam needed for many industrial processes. Efficient burner Boilers are required to provide the power and steam needed for many industrial processes. Efficient burner control ensures reduced fuel costs and lower emissions, and depends upon optimizing the combustion reaction between oxygen (from air) and the fuel used. An ideal ratio between the two ensures safe and efficient operation with minimal emissions.
Biomass boilers
Biomass boilers provide the power and steam needed for many industrial processes. Efficient burner control ensures reduced fuel costs and lower emissions, and depends upon optimizing the combustion reaction between oxygen (from air) and the fuel used. An ideal ratio between the two ensures safe and efficient operation with minimal greenhouse gas emissions.
Fired heaters
Fired heaters are direct-fired heat exchangers that use safe, efficient, and controlled combustion to raise the temperature of feed flowing through coils throughout the heater. They rely on efficient combustion to reduce fuel consumption, minimize emissions and ensure process safety. Depending on the use, these are called furnaces, or process heaters, and are critical to hydrocarbon processing.
Emission compliance in glass manufacturing
Glass production processes generate harmful gas emissions, particularly oxides of nitrogen (NOx), which are subject to environmental regulation. Compliance with these regulations must be demonstrated to avoid fines and other sanctions.
Kilns
Combustion control is important in a kiln, but can prove challenging due to the high temperatures, high variability in fuel sources, and high levels of dust and particulate matter. Efficient control of the combustion processes in cement and lime production can help reduce the fuel costs involved in creating the significant amounts of energy required, and also lower emissions, by emission monitoring and control.
Cement and lime production emission compliance
The manufacturing processes for both cement and lime involve mixing inorganic minerals calcined at high temperatures, generating high particulate levels. These processes leverage combustion and emission monitoring and control to ensure process compliance and efficiency.
Emission compliance in pulp and paper manufacturing
Pulp and paper production can generate harmful gases and particulate matter, which are subject to environmental regulation. Compliance with these regulations must be demonstrated to avoid fines and other sanctions.
Thermal oxidizers
Thermal oxidizers are specifically designed for air pollution control, receiving many of the waste streams from the production plant. Variability in the waste compositions requires constant adjustment of the burner air-fuel ratio, and the swift monitoring of oxygen levels ensures proper destruction removal efficiencies of all emissions.
Emissions compliance in mining
Metal and mining processes generate harmful gas emissions, particularly oxides of nitrogen (NOx), which are subject to environmental regulation. Compliance with these regulations must be demonstrated to avoid fines and other sanctions.
Power and steam generation
Controlling the ratio of air and fuel in combustion is key to safety, efficiency and cost-effectiveness. It also impacts upon the pollutant emissions that may be generated by combustion.

World leader in stack gas monitoring systems for decades and pioneer in FTIR technology, ABB Analytical is offering an inexpensive and forward-looking system with the ACF-NT multi-component analysis system for emission and process monitoring.
Accuracy, selectivity and reliability
The sampling probe, sampling line and analyzer cell are heated allowing water vapor to be measured along with extremely low detection levels of pollutant such as HCl, NH3 and HF. The sample gas delivery is using an electronically controlled air injector, which creates a vacuum. This draws the sample gas into the analyzer cell without the use of a mechanical pump. Thus, no moving part is used resulting in less maintenance. As a beneficial side effect, the sample gas is diluted at the analyzer cell outlet, condensation is reduced and disposal of the exhaust gas is safer.

What is AIM?
AIM is easy to use predictive maintenance software and an analyzer data collection for operators and reliability engineers similar to AMADAS to get insight into their measurement and analyzer equipment.
How is AIM applied in a CEMS?
Emission monitoring is essential for reporting emission values on regular base to emission authorities.
Plant operation needs to report emission values on regular base to emission authorities. The validation and calibration data of 4 stacks need to be logged continuously. Therefore, a breakdown of these measurements needs to be prevented. There is a need for easy use and interpretation of the measuring results. In addition, further discussion with authorities needs to be prevented, by presenting results in an accurate and standardized way.
The result of using AIM for emission monitoring and reporting
By carefully monitoring the overall status of the emission monitoring system via different graphic images the “loss of measurement” is prevented. Easy reporting prevents discussion with authorities and gives a calculation of emission load.

Frequently asked questions about Continuous Emission Monitoring System
CEMS stands for Continuous Emission Monitoring System.
A Continuous Emission Monitoring System (CEMS) is an integrated system used to continuously collect, record, and report data on the emission of pollutants from industrial processes, ensuring compliance with environmental regulations.
A CEMS analyzer is a device within the CEMS that measures specific pollutant concentrations in the emissions. It can detect gases like SO2, NOx, CO2, and other harmful substances to monitor and control air pollution levels.
Emission refers to the release of pollutants, such as gases or particulates, into the atmosphere from industrial processes, vehicles, or other sources, contributing to air pollution and environmental impact.
