  • 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 ...

  • 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. ...

  • 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 ...

  • How Does a Gas Analyser Work?

    Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...

  • Hydrogen Sulfide Continuous Emission Monitoring of Odor Control Systems

    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 ...

  • X-Ray Fluorescence-Based Multi-Metal Continuous Emission Monitor

    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 ...

  • Continuous noise monitoring for environmental application

    The increasing awareness of the public of environmental issues such as CO2 emissions, carbon footprints and waste recycling has brought the issue of environmental noise to the fore. Many of the demands of modern society result in the creation of noise sources such as larger airports, additional power stations and higher road traffic levels. In addition to this, the expansion of towns and cities, ...

  • Continuous emission monitoring and control of packed tower odor control systems using the sycamore CEM

    ABSTRACT Packed-tower chemical scrubbers, with sodium hydroxide (caustic) and sodium hypochlorite (bleach), are commonly used to treat foul air from wastewater treatment processes. The available control mechanisms include a pH probe and controller for the sodium hydroxide feed, an oxidation reduction potential (ORP) probe with a controller toestablish the bleach feed, and proprietary ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
