Download An Evaluation of Disposal and Utilization Options for Advanced Coal Utilization Wastes Book in PDF, ePub and Kindle
If the US is to continue to effectively use its substantial coal reserves, new clean coal technologies must be developed to improve power production efficiency and reduce emissions from power plants. In order to gain information about wastes produced by advanced coal utilization processes, a research project is being conducted to characterize the geotechnical and geochemical properties of advanced coal process wastes. The University of North Dakota Energy and Environmental Research Center (EERC) analyzed 34 of these wastes for their bulk chemical and mineral compositions and for the disposal-related physical properties listed in a table. This paper discusses potentially useful waste management practices for eight bulk waste samples obtained from four different clean coal processes: gas reburning with sorbent injection (GRSI); pressurized fluidized-bed combustion (PFBC); SO(subscript x), NO(subscript x), RO(subscript x), BOX (SNRB); and coal reburning (CR). All four processes have been demonstrated at either full-scale or pilot-scale facilities in the US. Since the properties of advanced process wastes are different from conventional coal combustion wastes, an analysis was performed to identify any potential problems that could occur when standard, off-the-shelf waste management technologies are used for handling and disposal of advanced process wastes. When potential problems were identified, possible alternative technologies were evaluated.

Download Evaluation of Hyperbaric Filtration for Fine Coal Dewatering Book in PDF, ePub and Kindle
Most of the coal presently used by the utility industry is cleaned at preparation plants employing wet processes. Water, while being the mainstay of coal washing, is also one of the least desirable components in the final product. Coarse coal (+3/4 inch) is easily dewatered to a 3--4 percent moisture level using conventional vibrating screens and centrifuges. However, the main problem of excess product moisture occurs in fine (minus 28 mesh) coal and refuse. Even though fines may constitute only about 20 percent of a contemporary cleaning plant feed, they account for two-thirds of the product surface moisture. This high surface moisture offsets many of the benefits of coal cleaning, and can easily undercut the ongoing programs on recovery of fine clean coal from refuse as well as producing an ultra-fine super clean coal fuel. Currently, most of the coal preparation plants utilize vacuum disk type technology for dewatering of the fine coal, providing dewatered product containing about 25 percent moisture. The coal industry would prefer to have a product moisture in the range of 10 to 15 percent, thereby avoiding thermal drying of coal. Hyperbaric filtration. has shown potential in lowering moisture in fine coal to about 20 percent level. This project will develop fundamental information on particle-liquid interaction during hyperbaric filtration and apply the knowledge in developing optimum conditions for the pilot plant testing of the hyperbaric filter system.
