Abstract:
Dry type acid gas pollutants removal processes offer the significant advantages of low capital and operating costs when compared to wet type acid gas removal processes. They hold great potential for the reduction of SO2 and HCl emissions from power and incineration utilities that use high-sulfur coal and high halide base acids wastes. One of the project's major goals was the development of dry, calcium-based sorption processes for removing sulfur dioxide and hydrogen chloride from the combustion gases and incineration gases produced by high-sulfur coal and high halide base acids wastes.
Dry sorbent circulating reactor system for flue gas cleaning highlights a number of experimental research findings that have had a significant and lasting impact in terms of scientific understanding. For example, the experimental investigation in demonstration test unit SO2 and HCl capture by dry sorbent obtained a removal efficiency of more than 99%, thereby revealing the well fluid mixing with sorbent and flue gas and longer residence time in the reactor. We also identified a number of important areas for future research, including reaction mechanisms, sorbent material, transport effects, simulation of particle fluid dynamics and efficient system development. Dry sorbent circulating reactor system includes the sorbent storage silo, precision feeding and injection units, main reactor, bag filter, recycle unit, induced draft fan and control unit.
Dry sorbent circulating reactor system for flue gas cleaning will appeal to chemical and environmental engineers who examine different ways to use coal and waste in a more environmentally benign manner. It will make an essential reference for air pollution control researchers from coal, lime, cement, and utility industries.
