The authors have successfully developed novel efficient and cost-effective sorbent and oxidant for removing mercury from power
plant flue gases. These sorbent and oxidant offer great promise for controlling mercury emissions from coal-fired power plants
burning a wide range of coals including bituminous, sub-bituminous, and lignite coals. A preliminary analysis from the bench-scale
test results shows that this new sorbent will be thermally more stable and cost-effective in comparison with any promoted
mercury sorbents currently available in the marketplace. In addition to the sorbent, an excellent elemental mercury (Hg(0))
oxidant has also been developed, and will enable coal-fired power plants equipped with wet scrubbers to simultaneously control
their mercury emissions as well as their sulfur oxides emissions. This will work by converting all elemental mercury to an
oxidized form which will be removed by the wet scrubber. This will result in significant cost savings for mercury emissions
control to the atmosphere, and will help in keeping electric costs low. The sorbent and oxidant will benefit from the utilization
of a waste stream from the printed circuit board (PCB) industry, and would thus be environmentally beneficial to both of the
utility and electronics industries. The sorbent also demonstrated thermal stability up to 350°C, suggesting a possibility
of an application in pulverized coal-fired power plants equipped with hot-side electrostatic precipitators and coal gasification
plants. 相似文献

In this paper new analytical inspection strategies, based on hyperspectral imaging (HSI) in the VIS–NIR and NIR wavelength ranges (400–1000 and 1000–1700 nm, respectively), have been investigated and set up in order to define quality control logics that could be applied at industrial plant level for polyolefins recycling. The research was developed inside the European FP7 Project W2Plastics “Magnetic Sorting and Ultrasound Sensor Technologies for Production of High Purity Secondary Polyolefins from Waste”. The main aim of the project is the separation of pure polyethylene and polypropylene adopting an innovative process, the magnetic density separation (MDS). Spectra of plastic particles and contaminants resulting from post-consumer complex wastes and of virgin polyolefins have been acquired by HSI and by Raman spectroscopy. The classification results obtained applying principal component analysis (PCA) on HSI data have been compared with those obtained by Raman spectroscopy, in order to validate the proposed innovative methodology. Results showed that HSI sensing techniques allow to identify both polyolefins and contaminants. Results also demonstrated that HSI has a great potentiality as a tool for quality control of feed (identification of contaminants in the plastic waste) and of the two different pure polypropylene and polyethylene flow streams resulting from the MDS-based recycling process. 相似文献
