Abstract. Simultaneous real-time changes in mercury (Hg) speciation- reactive gaseous Hg (RGM), elemental Hg (Hg°), and fine particulate Hg (Hg-PM2.5), were determined from June to November, 2007, in ambient air at three locations in rural Central Wisconsin. Known Hg emission sources within the airshed of the monitoring sites include: 1) a 1114 megawatt (MW) coal-fired electric utility generating station; 2) a Hg-bed chlor-alkali plant; and 3) a smaller (465 MW) coal-burning electric utility. Monitoring sites, showing sporadic elevation of Hg°, Hg-PM2.5, and RGM were positioned at distances of 25, 50 and 100 km northward of the larger electric utility. Median concentrations of Hg°, Hg-PM2.5, and RGM were 1.3–1.4 ng m−3, 2.6–5.0 pg m−3, and 0.6–0.8 pg m−3, respectively. A series of RGM events were recorded at each site. The largest, on 23 September, occurred under prevailing southerly winds, with a maximum RGM value (56.8 pg m-3) measured at the 100 km site, and corresponding elevated SO2 (10.4 ppbv; measured at 50 km site). The finding that RGM, Hg°, and Hg-PM2.5 are not always highest at the 25 km site, closest to the large generating station, contradicts the idea that RGM decreases with distance from a large point source. This may be explained if: 1) the 100 km site was influenced by emissions from the chlor-alkali facility or by RGM from regional urban sources; 2) the emission stack height of the larger power plant promoted plume transport at an elevation where the Hg is carried over the closest site; or 3) RGM was being generated in the plume through oxidation of Hg°. Operational changes at each emitter since 2007 should reduce their Hg output, potentially allowing quantification of the environmental benefit in future studies.

Taking the initial design value for target power plant as standard index values, two comprehensive benefit index systems for flue gas desulphurization (FGD) technology were formed by mean square difference method with or without the index of earning of by-product, to analyze the environmental benefit, economic benefit, technology benefit and comprehensive benefit of six flue gas desulphurization technologies on designed power plant and obtained the optimal technology ultimately. For the index system with index of earning of by-product, the optimal FGD technology is wet ammonia desulphurization, not only possesses the biggest comprehensive benefit, but also the biggest economical and technology benefit for designed power plant. For the index system without the index of earning of by-product, the wet ammonia desulphurization, limestone wet desulfurization and simple wet desulfurization have similar comprehensive benefits, but individual advantage on environmental, economic and technology benefit separately.

Fly ash obtained from a coal burning power plant was used to separate dissolved component of unleaded fuel from water using column chromatography. The results of this study indicate complete removal of the unleaded fuel from water. Eluted water collected from fly ash packed column has no odor. A successful field test at a larger scale shows the real environmental benefit of using this approach for removal of environmentally hazardous materials.

Efficiency power plant (EPP) promotes the use of energy efficiency power plant technology and energy efficient equipment, coupled with its low-input, zero pollution, zero emissions, and other advantages, having an important role in the control of energy consumption and energy saving. In order to carry out scientific EPP investment decisions, the level of energy efficiency is an important basis for investment decisions. This paper introduces total factor energy efficiency (TFEE) in energy efficiency calculation of EPP, constructs energy efficiency calculation model considering environmental benefits, and takes the micro and macro cases in China for analysis; the results show that the TFEE of both single energy efficiency project and EPP are at a relatively high level (above 0.7), and there is a huge gap between calculation results considering and without considering the environmental benefit. In order to discuss energy efficiency influencing factors, the paper analyzes generalized technological advances variation feature of China typical provinces implementing EPP based on generalized technological advances decomposition model by Malmquist index, finding that the steady growth ofMindex in these provinces is derived from the management level of implementation of EPP and the large-scale production capacity of formation and management. We hope the models and conclusions could provide some references on EPP energy efficiency calculation and decision.

China has mainly power generation capacity of coal-fired power plants. Coal-fired power plants account for about 80% of total power generation capacity in total annually. It will inevitably lead to a large amount of pollutant emissions, therefore, IGCC technology is particularly important to promote. This paper intends to analysize the environmental benefit and economic benefit of the IGCC technology used in the power plant based on the developed methodology. The purpose is to understand the advantages of IGCC technology for energy conservation and emissions reduction in the electric power industry to provide better technical references.

High Pollution

In order to improve the situation that there is a high pollution emission from coal-fired power plant in China and after a lot of research on inter-regional power generation exchange, we find that pollution emission would be reduced by exchanging power generation in the inter-regional coal-fired power plant. Taking the quantity of coal saving, economic benefit and environmental benefit into account, this paper proposes an analysis model for calculating the quantity of coal saving, added value and pollution reduction in the inter-regional power generation exchange, analyzing the benefit brought by this exchange. The case study shows that by using this model, pollution emission would be reduced in the whole region and economic and environmental benefit would be added in both electricity buyers and sellers. This analysis model has an application value.
