Enhancing Continuous Emission Monitoring Solutions: The Role of Optical Gas Imaging
Continuous emission monitoring is vital for industries to adhere to environmental regulations and mitigate the impact of pollutants on public health and the environment. Optical Gas Imaging (OGI) has emerged as a potent tool in this regard, offering real-time detection and visualization of gas leaks. However, ensuring reliability and minimizing false alarms remains a challenge. In this article, ...

Managing continuous emissions monitoring systems
With recent rulemaking governing compliance determinations in regards to the emissions of nitrogen oxides (NOx) and highly reactive volatile organic compounds (HRVOCs), the Texas Commission on Environmental Quality (TCEQ) required more frequent monitoring which resulted in the installation of more monitoring systems at the facility. This large Gulf Coast refinery decided to utilize the ...

Continuous Emissions Monitoring of Total Mercury
Over the past decades, mercury (Hg, quicksilver) has gone from being a versatile commodity used in everything from thermometers to herbicides, to a partially banned substance, which name alone signals environmental issues and health concerns. Today, much use of mercury has been phased out in favour of more environmental- and health-friendly substances, and the remaining circulation of mercury is ...

Continuous Emissions Monitoring Equipment – Guidance & Selection
There has never been such a wide range of analysers and systems available for continuous emissions monitoring as there is today. In the UK there are over 12 manufacturers and distributors offering CEMS (continuous emissions monitoring systems) using a variety of technologies including UV and IR absorption, FTIR, DOAS, chemiluminescence and photoacoustic spectroscopy (PAS). The majority of CEMS ...

Continuous Emissions Monitoring Systems for Industry
Across the globe, environmental regulatory authorities require manufacturing industries to monitor their pollutant emission rates. The most common means of measuring emissions is with continuous emissions monitoring systems, which are a packaged system of gas analyzers, gas sampling system, temperature, and flow and opacity monitors which are then integrated in with a system for data acquisition. ...

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 ...

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 ...

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 ...

Introduction to Quality Assurance of Continuous Emissions Monitoring
Large industrial plants are required to have and maintain an efficient process of Continuous Emissions Monitoring. In order to indicate that their processes are effective, and their emission monitoring systems meet the required criteria, there are carefully drafted EN Standards for assuring the high quality of permanently installed automated monitoring systems (AMS). In this article we will ...

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 ...

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 ...

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 ...
