  • NOx Control on a Budget

    National, regional and local regulations to reduce NOx emissions have prompted the development and implementation of a number of NOx control technologies – from selective catalytic reduction and low-NOx burners to overfire air and flue gas recirculation. Induced flue gas recirculation (IFGR), a design derivative of conventional forced flue gas recirculation, has demonstrated NOx reductions as ...

  • Cost-Effective NOx Control for Air-Preheated Systems

    New advancements in combustion control technologies, such as flue gas recirculation (FGR) and low NOx burners (LNB), have made it possible to achieve ultra low NOx levels without using expensive post-combustion flue gas clean-up technology. For some natural draft units it may be possible to meet the most stringent of the NOx regulations with cost-effective combustion control technologies. For ...

  • Low-Nox Burner retrofit Experiences in Cracking Furnaces at Dow, Terneuzen

    Abstract: Dow Benelux B.V. (Dow) operates three ethylene plants from the Netherlands, all based within its Terneuzen facility. In 2009, Technip Stone & Webster Process Technology (Technip) studied options to reduce the NOx emissions from the cracking furnaces of cracker 1. The results of this study, combined with the experience elsewhere within the Dow Chemical Company, have been used to ...

  • Economic evaluation for air pollution control technologies selection in power plants processes

    Air quality legislation is entering a transformation phase, shifting the concept of atmospheric emission control towards pollution prevention and emission minimization through a more integrated approach. This transformation, along with public pressure and increased foreign trade, is providing industries with incentives to consider their effect on the environment and to take action where required. ...

  • `Sensitivity of Condensable Particulate Matter Speciation on Predicted Visibility Impacts – Case Study,` presented at the NCASI West Coast Conference, September 2005

    Introduction This paper evaluates a realistic case study for an existing major emission source that is required to evaluate visibility impacts at a nearby federally-protected Class I area. The fictitious source is a 1960's era coal-fired electric generating unit (EGU) characterized as a pulverized coal-fired, dry bottom, wall-fired boiler equipped with PM and NOx controls (i.e., ...

  • Theory of Cost Effective NOx Control

    NOx is one of the primary air pollutants emitted from combustion processes and environmental regulations are the only driver forcing industry to install NOx control systems. In the Houston Galveston area alone, there is over 6,000 point sources that would need to be controlled to comply with the new State Implementation Plan adopted by the TNRCC. Many in the industry are in the process of ...

  • Advanced SNCR - NOx Reduction on Large Utility Boilers

    Fuel Tech has recently completed full-scale demonstrations of Advanced Selective NonCatalytic Reduction systems on a number of large utility boilers (>600MW) firing a variety of fuel types. The systems use the latest flexible injection technology and are controlled with a balanced algorithm utilizing unit load, a full grid of continuous furnace temperatures and the plant continuous emissions ...

  • The Other Side of Zirconium Oxide case study

    Regular Fuel Efficiency Applications Separate Oxygen and Combustibles Sensors In standard flue gas applications for Thermox analyzers, the user generally tries to extract the maximum energy from the fuel and transfers as much of that energy as possible to the process. These applications require the process to be operated as efficiently as possible by keeping both oxygen (excess air) and ...

  • Small project PSD cautions

    Following U.S. EPA’s promulgation of the PSD and Title V GHG Tailoring Rule, electric utilities, facilities with large industrial boilers, and other heavy industry manufacturing operations should be aware that the Prevention of Significant Deterioration (PSD) significance threshold for greenhouse gases (GHGs) may be the most stringent PSD triggering threshold for certain projects. Even ...

  • 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 ...

  • Urban Air Quality Management

    ' Poor air quality due to pollution is a serious environmental problem in most urban areas. The greatest burden of pollution is on human health. Urban air quality management requires an integrated approach that (i) identifies the most serious problems and measures that offer cost-effective and feasible solutions across a range of economic sectors and pollution sources including industries, ...

  • Solutions for Coating VOC & HAP Abatement

    Overview Our planet is getting warmer. At what rate it is occurring or how much human activity has to do with the increasing temperatures is a heated debate. One thing we do know for sure is that Carbon Dioxide (CO2) is a contributing factor in global warming and humans are responsible for a large portion of these emissions. These days, many individuals and businesses alike are trying to ...

  • What carbon footprint? Asks Corus

    Overview In case you haven’t heard, our planet is getting warmer. At what rate it is occurring or how much human activity has to do with the increasing temperatures is a heated debate, pardon the pun. One thing we do know for sure…carbon dioxide (CO2) is a contributing factor in global warming and humans are responsible for a large portion of these emissions. If you had asked ...

  • 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, ...

  • Federal transport rule — the “new cair” round 1

    On August 2, 2010, EPA proposed the long- awaited replacement for the Clean Air Interstate Rule (CAIR), which was rejected in 2008 by the D.C. Circuit Court of Appeals. Now called the Transport Rule (TR) by EPA, the new rule revises the CAIR approach to conform with the court ruling. In this first version (Round 1) of TR, overall emission budgets for NOX are similar to the initial period in CAIR; ...
