  • CEMS: An Overview

    We've written an overview to where CEMS are required, types of site that require CEMS and future requirements. Continuous Emissions Monitoring Systems are used to continuously collect, record and report data from industrial process operators that produce emissions to air. CEMS are used as a means to comply with ...

  • 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 ...

  • 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 ...

  • The Flexibility & Versatility of a Portable Emissions Analyzer

    Issue Fixed CEMS (Continuous Emissions Monitors) Measure at One Location CEMS are fixed units that typically only measure from one sample location which is usually on a main centralized stack. This main stack is often fed by several separate emissions sources throughout the plant such as boilers, heaters, engines, ovens, and furnaces. If the CEM ...

  • Modest Growth for Air Pollution Control Market

    The Clean Air Act amendments of 1990 created a wave of optimism in the air pollution control (APC) business. The subsequent decade, however, resulted in backwash of disappointment for APC companies as the market for stationary source equipment declined from 1-4% per year from 1993-1998. Growth returned to the APC market, however, with 1999 and 2000 characterized as 'good' years by the Institute ...

  • Innovative emissions monitoring uptake soars

    Firms in the UK’s waste and power sectors are proactively seeking Best Available Techniques for emissions monitoring, according to Enviro Technology. Over recent months there has been a surge in demand for sophisticated equipment, such as monitors of total gaseous mercury. The air quality and emissions monitoring specialist believes that a combination of factors, such as the recast ...

  • 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. ...

  • Navigating NSPS subpart Db for boilers: a case study

    Over the past year, Trinity assisted a chemical company with the permitting and installation of a new 220 MMBtu/hr package boiler. The new natural gas-fired boiler replaces coal-fired units that were installed in the 1940s. Navigating through the numerous, and at times conflicting, regulatory requirements applicable to such a unit has been challenging. With careful planning and implementation, ...

  • Mobile Stationary Source Emissions Testing, Coming to a Facility Near You?

    Last week, Antea Group had the unique opportunity to perform a RATA (relative accuracy test audit) of the emissions from a thermal oxidizer at an ethanol production facility located in Minnesota using a state-of-the-art mobile testing laboratory. During this RATA audit, actual stack emissions levels (including NOx, SOx, CO2, CO, O2, flow rate, temperature, velocity and pressure) from the ...

  • EPA mandatory reporting of GHGs rule

    Recent EPA Guidance EPA does not intend for the calibration requirements of 98.3(i) to apply to any units where the rule allows the use of “company records” to quantify fuel usage or other parameters; however, a facility’s GHG monitoring plan must include descriptions of the procedures and methods used for quality assurance, maintenance, repair of all flow meters ...

  • Cost Containment: Beyond the Obvious

    Utilities today can implement a number of different initiatives to help them contain costs and maximize profits. Some of those, such as switching to a more efficient fuel source if possible, can produce obvious results that are relatively easy to calculate. But there are other initiatives, though less obvious, that can produce significant results at the bottom line. One such cost-containment ...

  • Cementing the PC MACT

    On September 9, 2010, the U.S. EPA promulgated the final amendments to the National Emissions Standard for Hazardous Air Pollutants from Portland Cement Manufacturing Industry (40 CFR 63 Subpart LLL), also known as the PC MACT. EPA’s self-proclaimed “historic” rulemaking includes some important implications for cement manufacturers and other sources that may be subject to ...

  • Global solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...
