PHASE
II
FIELD
TESTING
OF
ADVANCED
MERCURY
CONTROL
TECHNOLOGY
Background
The
United
States
Environmental
Protection
Agency
(
EPA)
has
determined
that
regulation
of
mercury
emissions
from
coal­
fired
utilities
is
necessary.
Currently,
EPA
is
in
the
process
of
developing
maximum
achievable
control
technology
(
MACT)
regulations
for
new
and
existing
coal­
fired
electric
generating
units.
In
parallel
to
the
MACT
process,
several
proposed
legislative
measures
have
been
introduced
in
recent
sessions
of
Congress.

To
help
ensure
that
the
existing
fleet
of
coal­
fired
power
plants
can
meet
future
regulatory
requirements,
the
U.
S.
Department
of
Energy's
National
Energy
Technology
Laboratory
(
DOE/
NETL)
has
been
carrying
out
a
research
and
development
(
R&
D)
program
focused
on
the
control
of
mercury
emissions
from
coal­
based
power
systems.
Working
collaboratively
with
power
plant
operators,
the
Electric
Power
Research
Institute
(
EPRI),
academia,
state
and
local
agencies,
and
EPA
since
1990,
the
program
has
greatly
advanced
our
understanding
of
the
formation,
distribution,
and
capture
of
mercury
from
electric­
utility
boilers.
Continued
R&
D
is
necessary
in
order
to
bring
advanced
mercury
control
technology
to
the
point
that
they
are
ready
for
commercial
demonstration.

Program
Description
The
mercury
control
technology
research
activities
are
part
of
NETL's
Innovations
for
Existing
Plants
(
IEP)
Program.
The
IEP
Program
seeks
to
create
technology
options
that
will
enable
the
current
fleet
of
coal­
fired
power
plants
to
cost­
effectively
comply
with
future
environmental
regulations.
The
mercury
program
is
directed
at
the
development
of
a
broad
suite
of
low­
cost
control
options
to
respond
to
future
regulatory
decisions.
The
near­
term
goal
is
to
develop
mercury
control
technologies
that
can
achieve
50
to
70%
mercury
capture
at
costs
ranging
from
$
30,000
to
$
45,000
per
pound
or
less.
These
technologies
would
be
available
for
commercial
demonstration
by
2005
for
bituminous
plants
and
2007
for
lignite
and
subbituminous
coal
plants.
The
longer­
term
goal
is
to
develop
advanced
mercury
control
technologies
to
achieve
90%
or
greater
capture
and
would
be
available
for
commercial
demonstration
by
2010.

In
support
of
the
near­
term
goal,
DOE/
NETL
selected
eight
new
projects
in
September
2003
to
test
mercury
control
technologies
at
coal­
fired
power
plants.
The
projects
will
focus
on
longer­
term,
large­
scale
field
tests
on
a
broad
range
of
coal­
rank
and
air
pollution
control
device
configurations
(
See
Table
1).
These
tests
will
provide
important
information
on
mercury
removal
effectiveness,
cost,
and
the
potential
impacts
on
plant
operations
including
by­
product
characteristics.
A
second
round
of
proposals
will
be
due
by
the
end
of
April
2004.
DOE/
NETL
intends
for
the
second
round
to
focus
on
technologies
for
power
plants
that
burn
Powder
River
Basin
coal,
Texas
lignite,
or
coal
blends.
The
following
provides
a
brief
summary
of
each
of
the
eight
projects.

Mercury
and
Coal
By­
Products
Because
mercury
is
highly
volatile,
nearly
all
of
the
mercury
in
coal
vaporizes
in
the
boiler
and
exits
in
the
flue
gas.
Existing
air
pollution
control
devices
can
provide
some
degree
of
mercury
control
and
captured
mercury
may
reside
at
trace
levels
in
combustion
by­
products
such
as
fly
ash
and
FGD
material.
While
the
use
of
sorbent
and
oxidation
technologies
for
mercury
control
can
reduce
stack
mercury
emissions,
more
mercury
may
partition
to
the
solid
by­
products.

Coal­
fired
power
plants
generate
large
volumes
of
solid
by­
products,
which
can
present
significant
disposal
issues.
The
American
Coal
Ash
Association
estimates
that
the
electric
utility
industry
generated
more
than
117
million
tons
of
by­
products
in
2001.
In
addition,
future
SO2
regulations
may
result
in
even
greater
quantities
of
byproducts
being
generated
due
to
the
installation
of
wet
scrubbers.

While
almost
one­
third
of
the
total
amount
of
by­
products
presently
generated
is
beneficially
reused,
the
remaining
two­
third
is
disposed
of
in
landfills
or
surface
impoundments.
The
regulation
and
subsequent
control
of
mercury
emissions
from
coal­
fired
power
plants
could
lead
to
additional
scrutiny
of
current
by­
product
re­
use
activities
and
long­
term
management
practices.

In
recognition
of
the
potential
impact
of
mercury
regulations
on
by­
product
use
and
disposal,
DOE/
NETL
will
evaluate
the
leaching
and
volatilization
of

could
