  • Reaching Euro VI emissions limits

    The requirements of low and lowest detectable exhaust analysis has prompted Eco Physics to launch a broad range of analyzers for NO/NOx detection. Emissions tuning is one of the targets of the EURO VI regulations as well as US EPA 2010, which are: Reduction of Particulate Matter (PM) and reduction of Nitrogen Oxides (NOx). In the past 15 years – since the first European regulation for exhaust ...

  • Proposed boiler MACT sets aggressive emission limits

    On June 4, 2010, U.S. EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters at both major and area sources of hazardous air pollutants (HAP) emissions.  EPA proposed separate rules for units at major sources of HAP emissions (greater than 10 tons per year [tpy] of any single HAP and/or greater ...

  • Limiting greenhouse gas emissions: is the Cancun agreement enough?

    The objective set by the IPPC of limiting the increase in average global temperature to +2°C compared with the pre–industrial era is now accepted by all concerned. This ambitious objective was recognised at the Copenhagen Conference in 2009 and confirmed at Cancun in 2010. There are still no restrictive measures, but to achieve this objective, the main countries contributing to the ...

  • Delaying substantial emission reductions limits climate policy choices

    If fast and substantial reduction in greenhouse gas emissions is postponed further, there are fewer options available to stay below the 2 °C warming target for the end of the century. Delayed action is likely to require measures that remove CO2 from the atmosphere by planting forests and using bioenergy in combination with carbon capture and storage. The latter technique ...

  • Economic approaches to cost estimates for limiting emissions of carbon dioxide

    Without going into much detail, this paper gives an assessment of the relative strengths and weaknesses of a variety of economic approaches commonly used for cost estimates for limiting CO2 emissions, including the ad hoc approach, the dynamic optimisation approach, the input-output approach, the macroeconomic approach, the computable general equilibrium approach, and the hybrid approach. It ...

  • Boiler mact - what the new emissions limits on industrial boilers mean for you

    Generically known as “Boiler MACT”, the new possible industrial boiler limits directly address emissions of Hazardous Air Pollutants (HAPs) from industrial boilers and indirectly address the way that industrial sources operate their boilers. This white paper explains how Boiler MACT affects you and how to maintain operating flexibility while addressing compliance issues. The most ...

  • Pushing the Limits of Reengineering

    Cutting-edge turbine technology enables more efficient and cleaner power generation. However, the service of advanced gas turbines is challenging—especially when parts need to be replaced. The example of a blade replacement project shows how Sulzer establishes innovative reengineering processes and contributes to a secure energy supply that causes less carbon emission. A Sulzer ...

  • On the weaknesses and limitations of EPANET as regards energy

    With more than 1,500 citations in ranked journals and hundreds of thousands of downloads, EPANET is the benchmark software for analysis and design of pressurized water distribution networks. User-friendly, powerful and reliable, its public domain use has spread throughout the world. However, from an energy standpoint its capacity is limited to the point at which, in certain circumstances it ...

  • Limited provision of roads as a bottleneck on vehicle CO2 emissions in Asia: an international comparison of national trends

    This paper explores the relationship between road infrastructure, economic growth and road CO2 emissions. The basic premise is that many developing nations have achieved sufficient wealth to generate substantial demand for road vehicles, but that actual use is constrained by limited provision of surfaced roads. Our main result is that for comparable levels of income (GDP/capita), CO2 emissions ...

  • Canada's efforts towards greenhouse gas emission reduction: a case study on the limits of voluntary action and subsidies

    Canada has committed internationally to several agreements to limit climate change, most recently by ratifying the Kyoto Protocol in 2002. However, its domestic climate change policy is not reflective of these international commitments. In particular, federal government climate change policy over the last decade has emphasised noncompulsory policies such as voluntarism, information provision, and ...

  • Closing the emissions gap with peatlands

    The 18th conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) takes place against a backdrop of mounting evidence that time is running out to avert dangerous climate change. The United Nations Environment Programme (UNEP) has recently highlighted1 the large gap between current greenhouse gas emissions levels and reduction commitments, and the emissions ...

  • Overview of Emission Control Technologies

    Chapter 8. Emission Control Technology 8.4 Thermal Oxidation 8.4.1 INTRODUCTION The objective of this section is to present various VOC thermal oxidation technologies, their strength and weaknesses and the elements required to determine what is the preferred technology for a given application. In 1970 the environmental authorities started to identify various industries which had ...

  • Making money by reducing emissions

    Efforts to reduce emissions are really about changing companies' behavior. Pressure on companies from various activist groups combined with daily headlines in national and international media are driving various agendas among federal, state and local regulators. The current financial crisis does not appear to have lessened this pressure, rather the opposite. Compliance is now a must; ...

  • Emissions Trading (Cap and Trade)

    The Kyoto Protocol, adopted by 170 nations but not the US, established the initial carbon trading market. The goal of an emissions trading plan is to reduce emissions of greenhouse gases. Typically, a government agency sets an annual limit (cap) on the amount of emissions generated. Companies that emit greenhouse gases are given credits or allowances which represent the right to emit a ...

  • An end to the problem of particle emissions

    Austrian biomass heating systems guarantee an 80% cut in emissions. Recent studies have shown that these modern domestic boilers offer a significant reduction in particles, emitting fewer contaminating agents than previous generation boilers and wood stoves – with more than 100mg / ml of particles. The future will be based on new biomass combustion technology which cuts dust emissions from ...

  • Emission factors – what are they and what are they for?

    What are emission factors? Carbon emission factors, sometimes called carbon conversion factors, are used to calculate the carbon emissions arising from an activity. For the greatest accuracy, the best way to measure carbon emissions would be to monitor them directly as they are emitted, for example by placing a sensor in a power station chimney.  Given the large number of different sources ...

  • Peatlands: hotspots for emissions reductions

    Peatlands play a critical role in climate regulation, storing twice as much carbon as the entire world’s forest biomass and emitting large amounts of carbon when drained. Peat carbon stocks are distributed worldwide. The mitigation potential is very significant, but possible future possible emissions as well if no rapid action is taken to protect and restore them. The UNFCCC provides ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...
