Mercury (Hg) is one of the most toxic heavy metals, harmful to both the
environment and human health. Hg is released into the atmosphere from
natural and anthropogenic sources and its emission control has caused
much concern. This book introduces readers to Hg pollution from natural
and anthropogenic sources and systematically describes coal-fired flue
gas mercury emission control in industry, especially from coal-fired
power stations. Mercury emission control theory and experimental
research are demonstrated, including how elemental mercury is oxidized
into oxidized mercury and the effect of flue gas contents on the mercury
speciation transformation process. Mercury emission control methods,
such as existing APCDs (air pollution control devices) at power
stations, sorbent injection, additives in coal combustion and
photo-catalytic methods are introduced in detail. Lab-scale, pilot-scale
and full-scale experimental studies of sorbent injection conducted by
the authors are presented systematically, helping researchers and
engineers to understand how this approach reduces the mercury emissions
in flue gas and to apply the methods in mercury emission control at
coal-fired power stations. Readers will arrive at a comprehensive
understanding of various mercury emission control methods that are
suitable for industrial applications.
The book is intended for scientists, researchers, engineers and graduate
students in the fields of energy science and technology, environmental
science and technology and chemical engineering.
