Abstract |
The paper gives results of an examination of the capture of elemental mercury (Hg-o) and mercuric chloride (HgCl12) by three types of calcium (Ca)-based sorbents in a bench-scale study under conditions prevalent in coal-fired utilities. Ca-based sorbent performances were compared to that of an activated carbon. Mercury capture of about 40% (nearly half that of the activated carbon) was achieved by two of the Ca-based sorbents. The presence of sulfur dioxide (SO2) in the simulated coal combustion flue gas enhanced the capture of Hg-o from about 10 to 40%. Increasing the temperature in the range of 65-100 C also caused an increase in the Hg-o capture by the two Ca-based sorbents. HgCl12 capture exhibited a totally different pattern. The presence of SO2 inhibited the HgCl12 capture by Ca-basd sorbents from about 25 to < 10%. Increasing the temperature in the studied range also caused a decrease in HgCl12 capture. |
