FGD Wastewater Treatment is Hot Topic Hour – Thursday, June 16, 2011
The utility MACT and other coming rules for non-attainment will require nearly
every utility in the United States to install a Flue Gas Desulfurization (FGD)
system or upgrade their existing FGD system during the next few years.
Since it will be difficult for dry scrubbers to meet the new limits imposed by
the MACT and expected non-attainment rules for heavy metals, HCl, SO2
and particulates, wet scrubbers will be the most probable choice. However,
concurrently with the regulations that will require FGDs, states are tightening
surface water discharge limits on trace metals, salts, nitrogen, TSS and other
pollutants to meet National Pollutant Discharge Elimination System (NPDES)
requirements for surface water discharge and regulations on impoundments of
wastewater are also being tightened. Utilities are
facing increased pressure to eliminate wastewater discharge and to move toward a
zero discharge or near zero waste facility. Therefore, the impact on a facility
water treatment system will be a very serious concern when selecting and FGD
design.
It is not an easy task to design an FGD wastewater treatment system that meets
or exceeds discharge regulations because the quantity and composition of FGD
discharge water varies widely based on the boiler rating, scrubber type, the
efficiency of flyash removal, the efficiency of the dewatering system and the
composition of the coal, limestone and make-up water used. Most FGDs discharge
purge or wastewater that is slurry of water, dissolved solids, and suspended
solids laden with heavy metals and salts.
The following speakers will discuss their experience with developing, testing,
designing and troubleshooting treatment technologies for FGD wastewater, the
advantages and disadvantages of the currently available options including
capital and operating costs and the latest state-of-the-art technologies for
treating, minimizing or eliminating the wastewater that is generated by wet FGD
systems.
Ruediger Peldszus,
Senior Manager for Applied Technology, Advanced Intermediates at Evonik Degussa
GmbH, will discuss TMT 15® for separating heavy metals from flue gas
scrub water. TMT 15®, a heavy metal precipitant has proven
particularly successful in the treatment of effluents containing toxic heavy
metals. The success of TMT 15® in several hundred plants all over the
world is based on proven effectiveness and excellent toxicological/ecological
data combined with a well-known safe handling. This presentation touches on the
chemistry and application notes ranging from precipitable metals, addition
points and rates as well as practical data. The stability of resulting metal-TMT
precipitate will also be addressed, along with the relative benefits of using
TMT over other precipitating agents. TMT 15® can be viewed as
state-of-the-art and the active material is announced as Best Available
Techniques (BAT) for waste incineration by the European Commission.
Michelle L. Briscoe,
VP of Analytical Services at
Brooks Rand Labs, will discuss analyzing FGD
wastewater for heavy metals. Evaluating the effectiveness of specific FGD
wastewater heavy metal removal methods requires the collection and analysis of
samples for metals concentrations at each stage in the treatment process.
However, the unusual composition of FGD wastewater presents serious issues when
analysis is performed by testing laboratories using routine methods that can
result in inaccurate high concentrations being reported. Brooks Rand Labs, in
close cooperation with major research groups, electric utilities and engineering
firms has conducted extensive research and investigation into the development of
reliable analytical techniques to overcome the matrix-specific interferences and
produce far more accurate data for metals in FGD wastewater samples, even at low
concentrations.
Jay Harwood,
Commercial Leader for ABMet, at the GE Power and Water office in Oakville,
Ontario, will present GE's new modular Advanced Biological Metals removal system
(ABMet). ABMet is a proven, reliable process to remove elevated levels of
selenium and nitrate found in wastewater streams. Now all the benefits of ABMet
are available in a modular system for cost efficiency and time savings for the
customer. With its flexible, easy-to-install design, the modular ABMet system
provides unprecedented selenium removal for any location including flue gas
desulfurization blowdown.
William (Bill) A. Shaw,
P.E. Senior Process Engineer at HPD, a Veolia Water Solutions Company, will
discuss the CoLD(TM) Process which was developed to achieve zero
liquid discharge for wastewater from wet FGD scrubbers and IGCC 'grey water'.

NOx Control Market to Reach $7.6 Billion This Year
The market for selective catalytic reduction (SCR) systems and replacement
catalyst will reach a record $7.6 billion this year. This is the latest forecast
in NOx Control World Markets published by the McIlvaine
Company (www.mcilvainecompany.com).
Sales of systems are projected at $6.1 billion. This includes the ammonia
injection system, the catalyst, housing and all the ductwork and other
components contracted with SCR system suppliers such as Babcock Power, Alstom,
or Babcock & Wilcox.
2011 Worldwide SCR Systems & Catalyst Revenues ($ Million)
Catalyst |

SCR Systems |
$6,104.8 |
|
$7,614.3 |
Sales of catalyst are rising steadily. They will exceed $1.5 billion in 2011
mainly due to the replacement needs. The largest application is coal-fired
boilers where catalyst life is less than five years. Gas turbines are
another large application. Recently there has been a big market in the
U.S. for SCR systems for peaking turbines. This has created a need for high
temperature catalyst. Several catalyst suppliers have developed a product to
meet this need. However, many purchasers are avoiding the risk by using
conventional catalyst and bleeding in air to reduce temperatures.
The cement industry is the next big target for NOx control.
There are some SCR systems installed on cement kilns in Europe and a number
slated for future installation in the U.S. Waste incinerators and nitric acid
plants are other applications. Biomass-fired boilers present problems because of
the poisoning potential of constituents in the fuel.
Asia is the largest geographical market thanks to a big program in China to
install SCR systems on new boilers and retrofit SCR on older boilers in the more
populated areas. Japan, South Korea and Taiwan are also significant markets.
2011 SCR Systems & Catalyst Sales by Region ($ Million)

America |
$1,995.1 |
Asia |
$3,886.1 |
Europe |
$1,727.6 |
|
$7,614.3 |
The market in the U.S. is quite active due to recent regulations. It promises
further growth based on new ambient air quality rules. These will force
individual states to require NOx control not only on large coal-fired
boilers but on industrial boilers as well.
In Europe the biggest near-term potential is NOx control on
lignite-fired boilers which were not equipped with SCR originally due to the
lower NOx emissions and high cost. New EU regulations require
the larger lignite-fired boilers to reduce NOx by 2016.

Niche Knowledge Leveraging is the Key to Prosperity
The U.S. can maximize employment and GDP growth by leveraging niche knowledge.
This is the conclusion reached by the McIlvaine Company in the “World Market for
Your Products“. An example of this niche knowledge leveraging is another
McIlvaine service: “Power Plant Air Quality Decisions.”
GDP growth has slowed because the individual cannot keep up with developments.
Knowledge is doubling every year or two, but our ability to absorb it stays
constant. We, therefore, turn to others to take advantage of the
burgeoning knowledge. But the problem is that the world’s knowledge now
resides in millions of little niches. A handful of individuals somewhere in the
world have the best insights to help make a decision. The problem is finding and
utilizing them.
Google and other search engines are invaluable enablers. The problem is
that they are declassifiers when what we need is decisive classification.
Is a technology developing or mature? Is it more expensive or competitive
with existing alternatives? These are insights which cannot be found on
search engines. In fact, progress rests on decision systems which deliver the
four knowledge As: Alerts, Answers, Analysis and Advancement. The
niche expert is key to providing the “analysis.” Google and talking heads on
television can provide answers, but not necessarily correct analysis.
Leveraging niche knowledge is more than just extracting information from
experts. It requires a forum for niche experts to collaborate. Some
of the biggest opportunities are lost because one expert is not communicating
with another. In one recent McIlvaine Hot Topic Hour, a whole new
market for selenium removal with sorbents was discovered because air experts
communicated with water experts.
Harnessing the niche expertise will result in better decisions not only at the
micro level as per the above example, but on a very macro scale. In Power
Plant Air Quality Decisions it is shown that the best environmental and energy
security course for the U.S. is to immediately replace all coal-fired
power plants with new ultra supercritical coal-fired power plants. CO2
would be reduced by 30 percent and the cost of electricity would not increase.
This stimulus to the U.S. economy would be very substantial. Since this new
fleet of power plants would be designed for retirement before 2050, there would
be no long-term negative impact on greenhouse gas policy.
Search engines rely on computers. Decision systems require considerable
human input. So a proliferation of decision systems would require large
numbers of employees. The increase in average productivity of users will
increase substantially. This combination is the optimum route to full
employment and prosperity.

Renewable Energy Creates Many New Jobs
The renewable energy industry is an excellent creator of jobs as shown in recent
excerpts from McIlvaine Renewable Energy Updates.
Germany's solar photovoltaic (PV) industry now employs more workers than steel
production in the USA. With over 100,000 "green jobs" in PV alone, around 75
percent of European solar cells and modules as well as countless components are
made in Germany. Record-breaking domestic demand is a key industry driver, with
7.4 GWp of PV capacity installed in 2010. Germany is also a manufacturing
platform for other European PV markets: Italy's feed-in tariff revisions take
effect this month and include a Made in Europe clause, which is set to benefit
manufacturers based in Germany.
Suntech Power Holdings Co., Ltd. (NYSE: STP), the world's largest producer of
solar panels, has engaged a third production shift at its new solar panel
manufacturing facility in Goodyear, Arizona. The expansion adds another 30 solar
jobs to Arizona's fast-growing solar economy.
The state-of-the-art module manufacturing facility will now run twenty-four
hours per day with 107 employees. The new group of employees completed training
on May 13th, after weeks working side-by-side with the facility's existing first
and second production shifts. The expansion brings the facility's annualized
production throughput to about 50MW, representing 15,000 high-quality solar
panels per month.
Suntech's Goodyear, Arizona, manufacturing facility was opened in October 2010,
initially with 30MW of production capacity and 40 employees. The operation has
grown steadily since, taking on a second shift in January 2011, and remains
on-target to employ 150 employees by the end of 2011.
"We expect to expand the facility to reach up to 120MW of annual production
capacity within the next few years, particularly if Arizona's policy environment
continues to nurture the local market," said Steven Chan, President of Suntech
America. "We want to lead the charge to achieve energy independence in Arizona
and the United States."
SoloPower, a San Jose, California-based manufacturer of flexible thin film solar
cells and modules, announced that it has received a conditional commitment from
the U.S. Department of Energy (DOE) Loan Programs Office for a $197 million loan
guarantee. The funds will support construction of a facility that, when
completed and at full capacity, is expected to produce approximately 400MW of
thin film Photovoltaic (PV) modules annually.
SoloPower announced earlier this year that it had come to an agreement to
construct its first large-scale high volume manufacturing plant in Wilsonville,
Oregon. Retrofit of the existing building is scheduled to begin in the second
quarter of 2011. The factory is expected to provide direct employment to
approximately 500 people once it is running at full capacity. About 270
construction jobs will be created to build the plant, and additional jobs are
also likely to be generated in the local supply chain.
The Merricourt Wind Project recently received its Certificate of Site
Compatibility from the North Dakota Public Service Commission, delivering the
final state approval required for the project.
Merricourt is a 150-megawatt project being developed in southeastern North
Dakota by enXco, an EDF Energies Nouvelles Company. enXco and Xcel Energy
announced plans to develop and build the Merricourt Wind Project in November
2008
Merricourt will consist of 100 wind turbines and encompass approximately 18
square miles southeast of Kulm, on the eastern edge of McIntosh County and
western edge of Dickey County. It will provide renewable energy to approximately
43,500 homes and millions of dollars in economic benefits to the local area. The
project will also provide 150 construction jobs and 10 long-term, full-time
positions once in operation.
The McIlvaine Company has been tracking the energy field since 1974 and has been
following the renewable energy field for the last five years.
