The Pros and Cons of Predictive, Parametric, and Alternative Emissions Monitoring Systems for Regulatory Compliance
This paper closely examines the pros and cons of using predictive, parametric, and alternative monitoring techniques for regulatory compliance. While many predictive and parametric monitoring systems are less expensive to install and operate than CEM systems and demonstrate exceptional relative accuracy test results, this paper will provide the reader with a better understanding of the ...

How Does Continuous Emissions Monitoring Work?
Continuous emissions monitoring is a legal requirement in the US and many other countries to measure the emissions from smokestacks of industrial plants. Site owners are responsible for having functioning CEM systems in place and keeping them in good working order to monitor emission levels accurately. This article will outline how CEMS work, their main components and why they are ...

Multiplexed Monitoring – To be Doubt or Not?
There are several types of continuous emissions monitoring (CEM) systems. The technical designs may be very different, but they usually have a few things in common. The instruments providing the measurement results do not come cheap, and the systems require maintenance. However, if monitoring is to be done in more than one gas duct, then there might be a way to save costs, multiplexing. But ...

In-situ continuous emissions monitoring & regulatory compliance
As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

Plant operator problems with CEM’s - A common evaluation
ABSTRACT In situations where continuous monitoring systems (CEM’s) are available which have been ‘proven’ by regular use, the Regulator will normally require their use for the monitoring of airborne pollutants emitted by large plant. Disputes which arise between operators who purchase CEM systems and the system suppliers over the level of performance achieved are often ...

Continuous Emissions Monitoring – What, Why, and How?
In an ideal world, combustion merely gives emissions of water and carbon dioxide (CO2). Water is a non-issue while CO2 nowadays is looked upon with concern, giving its key role in the global climate changes. However, the issues with emissions do not stop there.The thermal processes also generate nitrogen oxides, primarily NO. Depending on the fuel composition, the type of combustion process, and ...

Who Needs Continuous Emissions Monitoring?
Continuous emissions monitoring (CEM) is about monitoring air pollutants generated by a specific activity and emitted to the ambient air, typically through a tall stack or other exhaust pipe. The “activity” can be some industrial process like a power plant or a waste incinerator, but it can also be on a much smaller scale such as a car equipped with an internal-combustion engine. The ...

Catalytic products international replaces RTO with a VECTOR Catalytic Oxidizer - Case study
A chemical processing facility recently installed a VECTOR Catalytic Oxidizer to replace a competitors Regenerative Thermal Oxidizer. The RTO was installed 5 years earlier and could not provide the reliability demanded by the client. The problem stemmed from a basic mis-application of the technology. As is very common, many air pollution control equipment manufactures have abandoned recuperative ...

Choosing flow monitors for CEMS applications
As a result of the 1990 Clean Air Act Amendments1, electric power plants must reduce their emissions of sulfur dioxide and nitrous oxides—the primary causes of acid rain. The U.S. Environmental Protection Agency (EPA), in its proposed rules2, designates the 111 Phase I fossil-fueled plants ^roughly 268 boiler units) that must have continuous emissions monitoring systems (CEMS) installed, ...

Extension of the agency’s monitoring certification scheme MCERTS to include continuous ambient air quality monitoring instruments
ABSTRACT The Environment Agency launched its Monitoring Certification Scheme MCERTS for continuous emission monitoring systems (CEMs) for industrial stacks at CEM98. At the time the Agency referred to its plans to broaden the Scheme later to include other monitoring activities. This paper presents details of the proposed extension of MCERTS to cover continuous ambient air quality monitoring ...

Comparing CEMS methods based on different principles: a revolutionary advance in real-time environmental monitoring
Environmental protection and monitoring are crucial to maintaining the ecological balance of the earth. Continuous Emission Monitoring Systems (CEMS) play a key role in this area, monitoring pollutants in the atmosphere in real time to ensure that businesses and governments comply with emission standards. This article will compare several CEMS methods with different principles, explore their ...

How has MCERTS impacted CEMS?
Industrial process operators that produce gas emissions to atmosphere are regulated by the Environment Agency. Monitoring of these emissions ensures that the environment is being properly protected and helps them manage their own impact on the environment. Under the Environmental Permitting Regulations, these sites are required to continually measure emission parameters from their chimney-stacks ...

The Working Principles of Continuous Emission Monitoring
Continuous emission monitoring—sometimes abbreviated to CEM—is a requirement established by the US Environmental Protection Agency (EPA) to ensure compliance with the appropriate emission standards. It is not mandated for all stack emission monitoring applications, but it is necessary for companies that need to demonstrate continual compliance or to determine exceedances of standards ...
