  • NOx and SOx Emissions Trading in Ontario

    Erik Haites outlines an unusual emissions trading programme due to begin next year. The government of Ontario recently announced its intention to establish an emissions trading programme for NOx and SOx emissions (oxides of nitrogen and sulphur) from all coal- or oil-fired electric generating plants in the province with a capacity greater than 25 MW beginning on 1 January 2001. This programme is ...

  • Measuring unburned carbon in flyash with an automated, on-line monitor

    Increasingly stringent NOx regulations have required plant operators to modify traditional combustion processes. SOx regulations and deregulation have forced plant operators to diversify their coal sources. And new mercury control requirements have been instituted by the U.S. Environmental Protection Agency. These changes challenge plant operators who are trying to achieve the low carbon levels ...

  • Lifecycle compliance 1.01

    With regulations increasing in number, scope,and complexity, managing the information associatedwith environmental health and safety(EH&S) compliance has become a complex,time-consuming, resource-draining and oftenexpensive task. Environmental compliancerequirements often dwarf those of Sarbanes-Oxley Act (SOX) in their breadth and sheer complexity.Because of the complexity of the ...

  • Micro-aeration for sulfide removal in anaerobic treatment of high-solid wastewater: a pilot-scale study

    The presence of sulfur compounds (e.g. protein, sulfate, thiosulfate, sulfite, etc.) in the feed stream generates highly corrosive and odorous hydrogen sulfide during anaerobic digestion. The high sulfide level in the biogas stream is not only poisonous to many novel metal catalysts employed in thermo-catalytic processes; but also reduces the quality of methane as a renewable energy. This study ...

  • The State of the Art in Gas Cleaning for the Fertilizer Industry

    INTRODUCTION The fertilizer industry has earned recognition for having contributed directly to increase world grain yields in the past century. Based on the conservative estimate of the world population growth, total fertilizer use in the future is expected to grow more than 200 million tons from the current level of 165 million tons. In U.S.A. and other countries the industries ...

  • NH3 Slip Monitoring in Fluidized-bed Catalytic Cracking Using the LDS 6 Gas Analyzer – Case Study

    Fluidized catalytic cracking (FCC) units are used in refineries to convert low value heavy oils into more valuable lighter compounds. Cracking units are sources of emissions of pollutants (e.g. NOx) and must comply with concentration permits set by local or federal authorithies. Modern technologies are applied to reduce the content of pollutants and to monitor certain gas compounds (here: NH3) in ...

  • Waste Water Treatment Plants

    In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within ...

  • Controlling Air Pollutants case study

    While it's not always easy to determine what's required for compliance, new technologies can help achieve air-pollution control Selecting air-pollution control equipment can be tricky. It's not only difficult to determine which pollutants must be controlled, but also which type of equipment will best control them to required levels for any given process or facility because there is no ...

  • 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 ...

  • WESPS continue to deliver

    Compliance with the increasingly stringent air pollution regulations of recent years is not the only reason forwardthinking industry leaders are adopting more sophisticated gas cleaning and air pollution control strategies. The desire to achieve higher performance efficiencies, control costs in a competitive marketplace, and stay ahead of the regulatory compliance curve is another driver of ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...

  • Incineration

    Introduction: High temperatures, 870 to 1,200 °C (1,400 to 2,200 °F), are used to volatilize and combust (in the presence of oxygen) halogenated and other refractory organics in hazardous wastes. Often auxiliary fuels are employed to initiate and sustain combustion. The destruction and removal efficiency (DRE) for properly operated incinerators exceeds the 99.99% requirement for hazardous waste ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • Reducing Routine Maintenance Costs of Engine Generator Sets with New Portable Oil Analysis Tools - Case study

    What do a hospital, a treatment plant a police station and a remote mine have in common? They have essential assets requiring uninterruptible power, commonly powered by an engine generator as primary or back up power. Engine generators, often termed "gen sets," combine an electrical generator and an engine. They supply electrical power where normal utility power is not readily available or is ...
