Dewatering of coal plant tailings: Flocculation followed ...

2011-1-1  Conclusions. Flocculation followed by filtration is a new concept for the dewatering of coal plant tailings. This study clearly indicates that the proper use of flocculant in filtration was very important to achieve efficient filtration performance. At the optimum dosage, the flocculant improved the dewatering process.

Carbon Capture from Coal Fired Power Generation

The most expensive part of the overall carbon capture and storage process is capturing CO 2 from a power plant. Maintaining coal as a viable source of electric power thus depends critically upon improving plant efficiency in order to produce less CO 2 for a given amount of power generation, and on finding more cost-effective ways to capture the CO
