  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Technical Challenges of Continuous Mercury Emissions Monitoring

    Many pollutants such as CO2, NOx and SO2 have been monitored continuously already for decades. In the last years the awareness for the need to measure mercury has also grown, and continuous mercury monitoring is becoming more and more relevant. Especially industries burning coal, oil or waste, share the responsibility to monitor their mercury emissions. All measuring techniques need to be able to ...

  • 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 ...

  • 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 ...

  • 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 ...

  • How to Monitor Mercury Emissions

    In recent years, mercury levels in the environment and in the food chain have risen substantially mainly due to human activities. As a long-range pollutant it can affect areas located thousands of kilometers away from its original source of emission. It’s no wonder then that the regulatory pressure to monitor mercury emissions grows stronger.  Before diving ...

  • Mapping Quality Assurance Requirements for Continuous Mercury Monitoring Systems

    The Clean Air Mercury Rule (CAMR) requires coal-fired electric power plants to install and operate mercury  continuous monitoring systems by December 31, 2008 such that they will have 12 months of “submittable” data by 1 January 2010. For all practical purposes, “submittable data” are “quality-assured data” that meet the extensive quality control requirements cited in the various regulations that ...

  • Biological monitoring system, iTOXcontrol, continues in Scarlino - Case Study

    The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these ...

  • Laser gas detector systems for greenhouse gas emissions monitoring

    Two types of portable laser based gas detector for measuring emissions of the greenhouse gases carbon dioxide (CO2) and methane (CH4) from oil and gas operations are described. A scanning open path detector was developed within a Cooperative Research and Development Agreement (CRADA) with the USEPA. This system scans multiple paths across an area source in rapid succession, enabling calculation ...
