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 (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 ...

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 ...

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 ...

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 ...

ABSTRACT This paper discusses the use of the Sycamore Continuous Emissions Monitor (CEM) for monitoring Hydrogen Sulfide Gas concentrations within odor control systems. The CEM is configurable as a single, two or three point system and can measure from 5 ppb to 2 PPM, 0.1 – 20 PPM, and 0 – 200 PPM and is designed for monitoring of scrubbers, carbon adsorbers, biofilters and biotrickling filters. ...

Gasmet’s vision is to live on a planet with less emissions. To fulfill this mission, we manufacture reliable and complete continuous emissions monitoring systems. We specialize in two different kinds of monitoring systems: 1) Continuous Mercury Monitoring system and 2) Continuous Emissions Monitoring system for other gas compounds. In this article we will introduce the latter: CEMS II e ...

Emission monitoring refers to the on-going processes of collecting the data on the gases and components released in the air by industrial plants. In this article we will discuss the ABC of emission monitoring at a general level: What is emission monitoring? What needs to be taken into consideration when planning a well-oiled measuring process? What Is Emission Monitoring? By regular and ...

ABSTRACT: Army demilitarization incinerators will need to comply with the Hazardous Waste Combustor National Emission Standard for Hazardous Air Pollutants that will regulate metals and metal compounds listed under the Clean Air Act Amendments. A large problem for these incinerator operations is limited knowledge of the type and quantity of emitted metals, so that compliance may be determined ...

Waste is generally undesired, and best not generated at all. The second best alternative to manage waste is to recycle it. However, there is also waste that for various reasons is not recycled. Landfills have then been the old-school solution, but it is for environmental reasons becoming a less viable option. What then remains is waste incineration, in most cases while recovering the energy ...

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 ...

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, ...

Introduction The continuous emission monitoring of the different compounds which are emitted by industrial facilities is an important topic to approve the compliance to different regulations like WID. However, there are several compounds which cannot be measured in real time. Specific dioxins/furans (PCCD/PCDF) and other POPs (Persistent Organic Pollutants) cannot be measured by online monitors. ...
