  • Pollution monitoring in Cement Industry

    The rising use of waste based fuels in the cement industry, both for economic and Environmental objectives, combined with the strengthening of air emission regulations around the world is pushing many operators to face a wider list of pollutants to monitor this, with associated costs. The design of appropriate solutions meeting local regulation is the key to maximize the cost benefit of the fuel ...

  • Air pollution control through kiln recycling by-pass dust in a cement factory

    Over the centuries, air pollution has increased from a local nuisance to a global problem (Emberlin 1998). Cement industry is one of the most important and strategic industries in Iran. However, its air pollution has been a serious problem. The primary related pollution is dust, which industrial countries have allocated tremendous efforts in reducing its volume. Dust in different stages of a ...

  • A Case Study in Implementation of the National Emission Standard for Hazardous Air Pollutants for the Portland Cement Industry at a Major Source

    The regulations at 40 CFR 63, Subpart LLL are commonly known as PC MACT because the rule establishes the maximum available control technology for hazardous air pollutants (HAPs) from portland cement plants in the United States. There are 188 HAPs specified in Section 112 of the Clean Air Act Amendments of 1990. Two classifications of HAP emitters are specified in 40 CFR 63. Major sources of HAPs ...

  • 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 ...

  • Total 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, ...

  • Air Rule for Cement Kilns Requires 92 Percent Cut in Mercury Emissions

    Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement industry said the cost to operate the required controls ...

  • Sources of PCDDs/PCDFs In Cement Kiln Emissions

    Abstract This paper presents data on the source of PCDDs/PCDFs in cement plant stack emissions, demonstrating that these emissions are not necessarily all created by the process. The data potentially demonstrates that some of the PCDDs/PCDFs in the emissions are pre-existing dioxins and furans that are vaporized out of the kiln raw feed. This calls into question the assumption that PCDD/PCDF ...


  • Waste incineration in cement plants: constraints and development opportunities (a French-German comparison)

    Is it possible to reconcile economic and ecological concerns? This article examines, through a French-German comparison, the case of obtaining a calorific value for wastes used as substitute fuels in cement kilns. On the one hand, this new strategy for obtaining needed inputs offers to the cement industry an economic opportunity for lowering production costs (the main determinant of ...

  • Air pollution impacts from carbon capture and storage (CCS)

    Carbon Capture and Storage (CCS) consists of the capture of carbon dioxide (CO2) from power plants and/or CO2-intensive industries such as refineries, cement, iron and steel, its subsequent transport to a storage site, and finally its injection into a suitable underground geological formation for the purposes of permanent storage. It is considered to be one of the medium term 'bridging ...

  • 3 Questions: Amanda Giang on controlling Mercury Pollution in India and China

    Original story at MIT News MIT graduate student studies how a new U.N. treaty could affect mercury emissions from coal power plants in Asia. The Minamata Convention on Mercury, a global treaty ...

  • Indicators of Pollution Management

    'The definition and selection of environmental performance indicators is still at an early stage but the use of indicators is increasing, both for the tracking of trends in pollution and other environmental issues at a large scale (national or regional) and also for the monitoring of Bank projects. This note provides a framework to assist in the selection of appropriate indicators for pollution ...


  • Controlling Stack Emissions in the Wood Products Industry & Wood Fired Boilers

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...

  • NOx in Non-Utility Industries - Part I NOx in Non-Utility Industries - Part I - Air emission origins, best control solutions and monitoring methodology for nitrogen oxides

     Problems with reducing nitrogen oxides (NOx) are widespread in the general process industries. These industries, together with medium size utility and power generators contribute about 15 percent of global NOx emissions. The emission sources addressed include various heaters employed in chemical and petrochemical plants, nitric and sulfuric acid plants, glass furnaces, iron and steel mills, ...


  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • PC MACT proposal may signal widespread change

    On May 6, 2009, EPA proposed amendments to the National Emission Standards for Hazardous Air Pollutants from the Portland Cement Manufacturing Industry (PC MACT) in response to numerous petitions and court mandates. The proposed revisions present significant challenges to the portland cement industry by establishing a new lower maximum achievable control technology (MACT) floor that would require ...

  • Study Charts a Future for Waste-Derived Fuels

    Pointers to possible future EU policy initiatives to give co-incineration facilities burning waste-derived fuels a strategic role in waste management have emerged in a study for the European Commission.1 The report suggests a policy focus on promoting source separation of municipal wastes, active discouragement of mass burn incinerators, and a levelling of the regulatory playing-field for ...

  • EPA isues GHG BACT guidance

    Beginning in 2011, major sources of greenhouse gas (GHG) emissions that trigger Prevention of Significant Deterioration (PSD) permitting must implement Best Available Control Technology (BACT) for GHG emissions from new and modified sources.
