Analysis of Dry Scrubber Options Will Be the Focus of the Hot Topic Hour on
March 27, 2014
The new format of the Hot Topic Hour will be discussions rather than
presentations. These discussions will be at a high level and focused on helping
decision makers choose among options. The discussions will be enhanced by
previous analysis and access to background documents. Subsequent to the
discussions, the analysis summarizing the benefits and disadvantages of each
option will be revised to reflect the insights garnered in the hot topic hour.
GOAL. To help purchasers determine the lowest life-cycle cost options to meet
process or regulatory goals.
PRELIMINARY PREPARATION. During the next month we will be gathering information.
Anyone will be allowed to submit data which, if deemed to be relevant, will be
posted to the applicable decisions system. This will give participants the
opportunity to be fully prepared for a high level discussion.
We will be reviewing Spray Drier Absorbers (SDA) and several specific types of
circulating dry scrubbers (CDS). They include GSA, NID and CFB. We will not be
addressing dry injection in this analysis. If these are not the three most
logical segments, then we need to discuss and re-label the categories. We will
ferret out differences among the technologies which should be considered when
selecting one of the dry systems.
We will review parameters such as:
• Response to load changes
• Lime consumption
• Lime quality
• Sorbent handling
• Capital cost
• Ability to retain high efficiency with coal sulfur above two percent
• Parasitic load
• Reliability and maintenance
• Component insights e.g., dual fluid nozzles vs. rotary atomizer
• Compatibility with downstream fabric filter or precipitators
• Space requirements
Background data on dry scrubbing supplied to participant on month prior to
discussion
Here are some samples of materials which will be available for analysis prior to
the session:

Detailed Analysis of GSA:
GSA specific questions:
1. Can you use GSA and not have to add fabric filter because a cyclone is
included?
Suppliers say it is possible to use with a precipitator. Considerations are gas
volume, temperature and moisture as well as particulate impact.
2. GSA can use slurry or separate water injection, is this an advantage?
Both options produce the same lime usage rates so either option is available.
2. Conventional CDS systems have a recycle duct from the outlet of the ID fan
and back to the inlet of the reactor for low load operation. How does the GSA
handle low load operation?
For variable gas flows, GSA uses two approaches: Incorporating a clean gas
recycle duct or by going to multiple modules. The turndown in any given reactor
is about 2:1. Supplier prefers ---------------

Billions of Dollars Will Be Spent For New Fabric Filter Technologies and
Applications
The fabric filter industry is undergoing a radical change which promises to
reshape the market. This is the conclusion of the McIlvaine Company in the
continually updated, World Fabric Filter and Element Market.
(www.mcilvainecompany.com)
One new technology is the ceramic filter element with embedded catalyst. Several
suppliers have successfully combined NOx reduction and particulate removal with
ceramic fibrous filter media with attached or embedded catalyst. This new media
is a big improvement over older monolithic block designs which did not lend
themselves to cleaning. Thousands of these elements are now in use on power
generation facilities burning biomass and other solid fuels. Others are used in
conjunction with driers and kilns.
The combination of membranes and application to pleated media is another step
forward. Several developments involve mercury capture. One company just
introduced a coating which will absorb mercury. Even though the mercury is not
purged, there is enough capability to function at high efficiency through the
expected two to three year life of the bag. Another variation uses a membrane
module for mercury capture. Successful commercial experience has been obtained
in Minnesota at a large coal-fired power plant.
The biggest change to the industry is going to come through the switching of
coal-fired boilers to fabric filters and away from electrostatic precipitators.
Potential markets in the U.S. and China would equal the entire present
industrial fabric filter market. New regulations are making it very difficult to
guarantee precipitator performance. Also, precipitator cost rises sharply as
efficiency requirements rise. A precipitator achieving 99.8 percent efficiency
is likely to be twice as large and expensive as one to meet 99 percent. Fabric
filter cost is only slightly impacted by efficiency requirements.

$185 Billion Market for Gas Turbines in U.S. over Next 27 Years
The conventional wisdom, as reflected in U.S. government forecasts, is that the
big increase in generating capacity in the U.S. will be for gas turbine and
combined cycle plants. This capacity will grow by 185,000 MW requiring an annual
investment of over $6.8 billion. These are the latest findings in Gas Turbine
and Combined Cycle Supplier Program published by the McIlvaine Company.
(www.mcilvainecompany.com)
Forecast of Fossil-Fired Generating Capacity
Fuel 2013 GW 2025 GW 2040 GW
Coal 254 254 254
Gas Turbine and Diesel 351 390 536
Fossil Total 605 644 790
The U.S. Energy Information Administration believes that the U.S. coal-fired
capacity will remain at 254 GW over the next 27 years, while the gas turbine and
diesel capacity will increase from 351 GW to 536 GW by 2040. Most of this
capacity will be combined cycle as opposed to simple cycle. Therefore, the
investment will be close to $ 1 billion per GW.
Peaking plants traditionally operated a short time per year when demand was at
its highest. Today, a gas turbine peaking plant may operate for a substantial
portion of the year to offset fluctuations in solar and wind generation. Since
the efficiency of combined cycle plants is much higher than simple cycle and the
greenhouse gas emissions much lower, regulators are demanding that peaking
plants not only incorporate the steam cycle, but that they also have efficient
NOx reduction and CO oxidation systems.

Deepwater Winds and Alstom Sign Major Turbine Agreements for Block Island Wind
Farm
Deepwater Wind and Alstom announced the signing of major agreements to supply
the Block Island Wind Farm with five of Alstom’s 6-megawatt (MW) Haliade 150
offshore wind turbines.
“This agreement represents a giant leap forward for the Block Island Wind Farm,
and the start of turbine construction just last month marked a major project
milestone,” said Deepwater Wind CEO Jeffrey Grybowski. “We’re thrilled to have a
company as renowned as Alstom as our turbine partner.”
Alstom will supply the five 6 MW turbines, including tower sections, for the
30-megawatt Block Island Wind Farm, located about three miles off the coast of
Block Island, R.I. In addition, under a separate agreement, Alstom will provide
long-term service and maintenance responsibilities for the turbines.
Under the turbine supply contract, Deepwater Wind made an initial multi-million
dollar payment to Alstom in December 2013 that allowed Alstom to begin the
manufacturing process for the turbines. Specifically, Alstom has begun
procurement of all 15 blades for the wind farm, which will be delivered to
Deepwater Wind in Europe in April 2014.
Lockheed Martin and Victorian Wave Partners Sign Contract to Start Development
of World’s Largest Wave Energy Project
To advance the availability of alternative energy solutions, Lockheed Martin
announced that it has signed a contract with Victorian Wave Partners Ltd. to
begin developing the world’s largest wave energy project announced to date. This
is a significant step toward making ocean energy commercially available.
The 62.5-megawatt peak power wave energy generation project will be build off
the coast of Victoria, Australia, using the PowerBuoy® wave energy converter
technology of Ocean Power Technologies (OPT). The project is scheduled to be
built up in three stages, with the first stage producing approximately
2.5-megawatt peak power. Once completed, the project is expected to produce
enough energy to meet the needs of 10,000 homes. As this project also
contributes to Australia’s goal of 20 percent renewable energy by 2020, it has
received significant grant support form ARENA (Australian Renewable Energy
Agency).
In this project, Lockheed Martin will provide overall project management, assist
with the design for manufacturing of the PowerBuoy technology, lead the
production of selected PowerBuoy components and perform system integration of
the wave energy converters.
SunEdison, PIF, Sanabil Investments take Steps to Advance Solar Energy Industry
in The Kingdom of Saudi Arabia
SunEdison Inc., a leading solar technology manufacturer and provider of solar
energy services, and the Public Investment Fund (PIF) of the Government of Saudi
Arabia and the Saudi Arabian Investment Company (Sanabil Investments), signed an
agreement to jointly fund a feasibility study for the establishment of a
vertically integrated solar PV (photovoltaic) manufacturing complex at Wa'ad Al
Shammal in Saudi Arabia. This follows a successful preliminary study between the
National Industrial Clusters Development Program (NICDP) and SunEdison in 2013.
The proposed project, entailing the production of polysilicon through modules,
would support the growth of the solar energy industry in the Kingdom.
The complex would utilize both SunEdison's proprietary high pressure silane
fluidized bed reactor (HP-FBR) polysilicon, and continuous Czochralski (CCz)
crystal ingot technology and equipment, as well as include solar wafer, cell and
module manufacturing, employ attractive debt financing for the approximately
$6.4B project, and would begin production in 2017, ramping to 3 GW (gigawatts)
annually. A significant percentage of polysilicon and ingot production would
support the 3 GW planned module output, with the remaining crystal production
addressing the market with a substantial cost advantage. Demonstrating strong
support, the Ministry of Petroleum and Minerals pointed out it will provide the
required quantities of natural gas, and the Saudi Electrical Company (SEC) will
provide the needed power requirements for the project.

“NOx Catalyst Performance on Mercury and SO3” is the “Hot Topic Hour” on
February 27, 2014
The utility and industrial boiler operators are preparing to deal with MATS, the
Cross State Air Pollution (transport) Rule (CSAPR) currently being reviewed by
the Supreme Court and NAAQS. Gas- and oil-fired turbines will also be impacted.
To avoid expensive additions to their APC equipment, operators should first get
the best possible performance from existing APC equipment. For those power
plants equipped with SCR or SNCR, this is a good place to start.
The NOx catalyst plays a key role in the emissions of mercury, SO3 and for
turbines CO. SCR catalysts that enhance mercury oxidation and minimize SO3
formation can be a cost-effective solution for power plants with existing
control equipment and those power plants considering addition of an SCR or SNCR.
Catalyst selection and management can have a substantial affect on the
achievable level of mercury oxidation and the resulting mercury capture. With
the proper catalyst, SCRs can convert a good amount of elemental mercury to
oxidized mercury in the flue gas when sufficient halogens are present. Scrubbers
for SO2 control are also typically very effective at removing the oxidized
mercury. This is good news for many power plants equipped with SCRs, because
compliance-level mercury removal can often be achieved without adding
mercury-specific controls. Catalysts can also minimize the formation of SO3
allowing other downstream equipment including air heaters to operate more
efficiently.
The following speakers will describe the catalyst technologies currently
available and under development with a discussion of their applicability to and
advantages for various power plant configurations, their NOx reduction
capabilities, their affect on mercury, SO3 and other pollutants, catalyst
management strategies to maximize mercury oxidation at minimum cost, while
maintaining DeNOx and SO2 conversion performance and the key issues to be
considered when selecting a catalyst.
John Cochran, President of IBIDEN CERAM Environmental, Inc.
Chris Reeves, Ph.D., Development Project Manager at Cormetech, Inc., will
present “SCR catalyst selection and management for improved Hg oxidation
performance.” Catalyst selection and management for Hg emission control is
analogous to that for DeNOx except for some key differences due to the nature
and complexity of the Hg0 oxidation reaction kinetics. Cormetech’s unique
capability of testing fresh and field deactivated catalysts has been used to
measure the influence of temperature, flue gas composition, catalyst type and
catalyst age on Hg oxidation activity, facilitating the development of
predictive models and advanced catalysts with significantly improved Hg
oxidation performance that maintain high DeNOx activity and equivalent SO2
oxidation performance. These tools form the basis of Cormetech’s COMET™
technology that can be applied to characterize and optimize the role of the SCR
system in Hg compliance strategies.
Brydger Van Otten, Chemical Engineer in the Engineering Research and Development
Department at Reaction Engineering International, will present “Evaluation of
Mercury Control Strategies in the Presence of SO3 Using the MerSimTM Model.” A
modeling study has been performed using REI’s mercury modeling tool MerSim to
investigate how mercury control strategies for a utility power plant may perform
in the presence of SO3. Co-benefit strategies as well mercury specific control
technologies were investigated for their ability to maintain performance in the
presence of increasing SO3 concentrations.
