Emissions-reduction strategies

Meanwhile, a quantitative approach to assessing pollution effects on ecosystems has already been developed. A Critical Load and Level (CLL) concept has been used for defining emission reduction strategies under the UNECE Convention on...

Such values are of importance for creation of optimization models and separate emission reduction strategies for both sulfur and nitrogen. When both species must be reduced, the approach described in Chapters 4 and 17 is used. 

The full potential for removing pyritic sulfur from various coals by physical coal cleaning is significant but difficult to achieve. However, SO2 control by precombustion removal of pyrite could be an important S02-emissions reduction strategy. The cleaned coal produced could be used in coal-fired utilities, constructed both pre-and post-NSPS, as well as in industrial boilers. To realize the potential for coal cleaning in actual practice, however, new techniques must be demonstrated in the laboratory and then at the "proof-of-concept" scale (approximately one ton of coal per hour). These new coal beneficiation techniques could be advanced physical-coal-cleaning (PCC) processes, or they could employ microbial desulfurization or chemical desulfurization to remove organic sulfur. These latter processes could be used by themselves or in concert with PCC processes. 

Source-receptor analysis was performed to allocate the air chemistry parameters to the individual emission sources. To estimate the impact of a source group on a certain pollutant, several simulations have to be accomplished. To minimize the associated uncertainties (non-linearity of chemical processes), the source group was suppressed. Due to the non-linear chemical processes, background concentrations and advection a non-linear fraction has to be introduced (DG-ENV 2001). The source-receptor analysis is an important tool for abatement and emission reduction strategies.

In principle, BAT(NEEC) and RACT offer the user flexibility in choosing an emission reduction strategy -choice between a variety of end-of-pipe abatement techniques, low solvent technologies, waste minimisation or any combination of these. It recognises that the most appropriate solution will vary from one application to another with size, product quality required and the age and location of a plant.

When considering emission reduction strategies, users are likely to have questions concerning the hnancial costs. The research team identified several variables that would be of interest to the user when addressing these financial considerations ... 

One of the fundamental needs of many users will be to better understand the local consequences of individual emission reduction strategies. Research focused on addressing the following questions about each strategy, which were then included in the Potential Impacts category ...
