Mercury capture by an activated carbon in a fixed-bed bench-scale system

摘要: The control of mercury emissions for utility power plants may become important because the Clean Air Act Amendments requirement that U.S. Environmental Protection Agency (EPA) assess health risks associated with these [1]. One approach removal, whichmay be relatively simple to retrofit (compared other methods [2–4]), is injection sorbents, such as activated carbon, upstream existing particulate devices. A study, sponsored by Electric Power Research Institute (EPRI) and Department Energy (DOE), being conducted at University North Dakota & Center (EERC) develop a sorbent-screening test protocol, screen potential sorbents in bench-scale fixed-bed system, provide data support efforts model capture mechanisms. proper protocol required establish repeatability results ensure reproducibility between different labs. To date, elemental tests have been completed several under various flue gas conditions. carbon-based sorbent used this study was lignite-based carbon (LAC), commercially available from American Norit Co., Inc. This paper presents more recent LAC mercury. has also others baseline [5–7].
