Adsorption of SOX and NOX in activated viscose fibers Anais da ABC (AABC)
Plens,Ana Carolina O.; Monaro,Daniel L.G.; Coutinho,Aparecido R..
SOx and NOx are emissions resulting from combustion processes and are the main agents that contribute to the formation of acid rain, which causes harm to humans and the environment. Several techniques for removing these pollutants are applied in i.e. oil refineries, thermoelectric that use petroleum oils and vehicular pollution. Among these, highlight the adsorption of contaminants by the usage of activated carbon fibers and activated carbon, which are characterized by high surface area and uniform distribution of pores, providing appropriate conditions for application in processes of removing environmental contaminants. In the present work, activated viscose fibers (AVF) were prepared and applied in adsorption experiments of NO and SO2. The materials...

Cost-Effective Reduction of NOx Emissions from Electricity Generation AgEcon
Burtraw, Dallas; Palmer, Karen L.; Bharvirkar, Ranjit; Paul, Anthony.
This paper analyzes the benefits and costs of policies to reduce nitrogen oxides (NOX) emissions from electricity generation in the United States. Because emissions of NOX contribute to the high concentration of atmospheric ozone in the eastern states that is associated with health hazards, the U.S. Environmental Protection Agency (EPA) has called on eastern states to formulate state implementation plans (SIPs) for reducing NOX emissions. Our analysis considers three NOX reduction scenarios: a summer seasonal cap in the eastern states covered by EPA's NOX SIP Call, an annual cap in the same SIP Call region, and a national annual cap. All scenarios allow for emissions trading. Although EPA's current policy is to implement a seasonal cap in the SIP Call...

Efficient Emission Fees in the U.S. Electricity Sector AgEcon
Banzhaf, H. Spencer; Burtraw, Dallas; Palmer, Karen L..
This paper provides new estimates of efficient emission fees for sulfur dioxide (SO2) and nitrogen oxides (NOX) emissions in the U.S. electricity sector. The estimates are obtained by coupling a detailed simulation model of the U.S. electricity markets with an integrated assessment model that links changes in emissions with atmospheric transport, environmental endpoints, and valuation of impacts. Efficient fees are found by comparing incremental benefits with emission fee levels. National quantity caps that are equivalent to these fees also are computed, and found to approximate caps under consideration in the current multi-pollutant debate in the U.S. Congress and the recent proposals from the Bush administration for the electricity industry. We also...

Restructuring and the Cost of Reducing NOx Emissions in Electricity Generation AgEcon
Palmer, Karen L.; Burtraw, Dallas; Bharvirkar, Ranjit; Paul, Anthony.
We look at the effects of restructuring on three issues: (a) economic surplus and environmental quality, (b) the cost of NOx control policies and who bears the costs, and (c) the cost-effectiveness of a seasonal and an annual NOx cap in the SIP Call region. We find that without the NOx cap, nationwide restructuring leads to higher NOx and carbon emissions from the electricity sector. Adding either a seasonal or an annual NOx cap-and-trade regime in the eastern United States mitigates the increase in NOx emissions but has a much smaller effect on carbon emissions. The out-of-pocket compliance cost associated with achieving a seasonal or an annual NOx cap is moderately higher with nationwide restructuring than without, but the changes in economic surplus are...
