Hot Gas Filtration at 850oF Will Change APC – Hot Topic Hour on May
1, 2014
The highly visible power plant steam plume directly correlates to lost energy,
water, CO2, and money. By filtering the gas before the SCR or
as part of the SCR and then following with a highly efficient heat exchanger,
all the losses become pluses. The challenge has been to develop a filter
to do this. Hot ESPs were developed in the U.S. but had operating and
efficiency problems. Rigid ceramic filters were unsatisfactory in terms of
maintenance and energy costs. Now, thanks to the latest flexible ceramic
media designs, the hot gas filter is now a commercial and attractive option.
We are setting up a whole website devoted to this important subject. Our
webinar on May 1st will be at a high level with a discussion rather
than long presentations. There will be some presenters such as Richard
Lydon of Clear Edge, but considerable time will be spent reviewing the range of
options available. They include:
·
Flexible ceramic filter elements,
·
Flexible ceramic filter elements with embedded catalyst,
·
Direct sorbent injection to add acid gas removal to NOx and
particulate,
·
Sorbent recovery and reuse with a double alkali system,
·
Metallic filters,
·
Low efficiency hot ESP to protect SCR and allow more efficient heat exchange.
The discussion will also include the ways that the 850oF heat can be
extracted from the flue gas prior to scrubbing. The two benefits are heat
recovery and elimination of the scrubber plume and lost water. The uses of
recovered heat such as condensers, ethanol, lignite drying, distillation of
seawater and zero liquid discharge will be discussed.
The primary focus will be on power plants, but other applications will be
covered as well. The fact that the hot ESP is prior to the SCR in a cement plant
is indicative of the need to share technologies among industries.

The expenditure for repairs and replacements will also be sizable. Over $400
million will be spent just for replacement filters for the turbine air intakes.
Over $1 billion will be spent for replacement parts and complete replacement
pumps and valves.
The amount spent for catalyst and for ammonia to reduce NOx will be
substantial, and is anticipated to grow robustly as most new units are required
to meet stringent air emission limits. The investment for treatment
chemicals is also increasing as most of the new units are utilizing steam
turbines in combined cycle operation.

Air Filter Sales Will Exceed $2.5 Billion in the Americas Next Year
Sales of air filters for purifying ambient and indoor air will exceed $2.5
billion in the Americas next year. This is the latest forecast in
Air Filtration and Purification World Market
published by the McIlvaine Company. (www.mcilvainecompany.com)
The U.S. will be the largest purchaser with sales exceeding all the other
countries in North and South America combined. However, the growth rate in
Brazil and Mexico is exceeding that of the U.S.

The biggest applications are residential and commercial buildings. Sales for
these applications will exceed $1.3 billion. In the power industry, the big use
is for filtration of the inlet air for gas turbines. These turbines are
used for electricity generation and for combined steam and power in the oil and
gas and other industries. The advantages of using highly efficient HEPA
filters have been proven. As a result, the industry is slowly moving
toward these more expensive filters for turbine intakes. This will create
a double-digit revenue growth over the next few years.
Bioclean applications include hospitals and pharmaceutical manufacturing plants.
The hospital market is relatively small compared to its potential. A greater use
of highly efficient filtration systems would substantially reduce transmission
of disease among patients and staff.
Many industrial plants incur substantial filter costs because they have a very
large intake of air. The reason is that they are discharging large quantities of
air through dust collectors. This loss must be replaced by ambient air.
Plants which have welding, woodworking, or machining operations are in this
category.
Another application is the use of air filters following dust collectors.
This combination is seen where the plant wants to return air for reuse in the
plant. The air needs to be cleaner than achieved with the dust collector.
Therefore, a HEPA filter is inserted in the recirculation duct.

Renewable Energy Briefs
CEMEX Announces Completion of Financing of One of the Largest Wind Farm Projects
in Latin America
CEMEX, S.A.B. de C.V. announced that it has successfully completed the financing
of Ventika, a project comprising the construction of two 126 MW wind farms each,
for a total nominal capacity of 252 MW to be located in General Bravo, Nuevo
Leon, Mexico.
The investment for the project is approximately U.S.$650 million, of which 75
percent correspond to debt and 25 percent to equity. The debt financiers are the
North American Development Bank, Banobras, Nafin, Bancomext and Santander. The
equity partners are Fisterra Energy, a company majority owned by funds managed
by Blackstone, CEMEX and private investors.
CEMEX developed the project, providing its industry-leading technical expertise
and skills in the clean energy industry. In addition, CEMEX will supervise the
construction process and, once operational; will manage the wind farms without
exercising control and owning a minority stake of 5 percent of the equity,
therefore, the project will not be consolidated into CEMEX’s balance sheet and
the project´s debt will have no recourse to CEMEX.
These wind farms will supply renewable energy to facilities belonging to FEMSA,
DEACERO, Tecnológico de Monterrey and CEMEX, under the self-supply scheme
approved by the Mexican Energy Regulatory Commission. In addition, more
off-takers could be brought in the near future.
Construction will begin in the 2nd quarter of 2014 and commercial operation is
expected by the 2nd quarter of 2016.
Diversified TEP Resource Plan Calls for More Renewable Energy, Less Coal
Tucson Electric Power (TEP) plans to meet customers' energy needs over the next
15 years by reducing its coal generation capacity by about one-third; acquiring
new cost-effective natural gas-fired resources; and continuing its expansion of
renewable power and energy-efficiency programs.
TEP's plans are outlined in the 2014 Integrated Resource Plan (IRP) the company
filed with the Arizona Corporation Commission (ACC) on April 1. The IRP
describes how TEP plans to meet energy demand requirements through 2028,
providing safe, reliable and reasonably priced service to customers while
satisfying regulatory requirements and improving the environment.
According to current projections, the company expects to add more than 50,000
customers over the next 10 years. Peak demand is projected to grow annually by
about 1 to 1.5 percent.
By 2028, TEP anticipates that its combined solar, wind, and biogas resource
capacity will increase from 157 MW today to 788 MW – enough energy to power
approximately 136,000 homes. TEP also plans to reduce its need for new
generating resources through a range of cost-effective, industry-proven
energy-efficiency programs that will result in a cumulative capacity reduction
of 312 MW, which is equivalent to the annual electric energy use of
approximately 167,000 homes.
By 2028, TEP projects that its resource portfolio will consist of 43 percent
coal-fired generation and 36 percent natural gas-fired resources. The remaining
21 percent will be made up of renewable energy and energy efficiency resources.
Scatec Solar Secures Final Approvals to Build 80 MW Utah Solar Park
Scatec Solar, the global independent solar power producer, received the final
approvals necessary to proceed with the building of an 80 MW (ac) PV
(photovoltaic) solar plant in Iron County, UT. The Utah Red Hills Renewable
Energy Park, set to be built on a site with excellent solar irradiation, will
generate around 210 million kilowatt hours (kWh) of electricity per year, which
will be fed into the grid under a twenty-year Power Purchase Agreement (PPA)
with PacifiCorp. Construction is estimated to start in the third quarter of 2014
and when complete, the plant will be Utah's largest solar energy generation
facility.
Scatec Solar entered into the twenty-year PPA with PacifiCorp for the purchase
of all of the project's energy output and capacity in December 2013. PacifiCorp
delivers electricity to customers in Utah, Wyoming, and Idaho through Rocky
Mountain Power.
The ground-mounted photovoltaic solar facility is being developed on
approximately 650 acres of privately-owned land in Parowan, UT; it will deploy
approximately 325,000 PV modules on a single-axis tracking system, and will
interconnect to an existing PacifiCorp 138 kV line in the adjacent Parowan
Valley Substation.
Integrated Gasified Biomass Power Plant Will Use GE Gas Engine Technology to
Help Bulgaria Achieve Greater Energy Independence
To reduce Bulgaria’s heavy dependence on imported energy, a landmark
biomass-to-energy plant powered by GE’s Jenbacher gas engine technology is
being built near Stroevo, in Plovdiv province.
The 5-megawatt (MW) Karlovo plant will use three of GE’s fuel-flexible, robust
and high-efficiency Jenbacher engines—one J612 and two J620 units—powered by
syngas derived from straw and wood chips and will produce enough electricity to
power 2,000 homes. Such organic waste is normally difficult to gasify
effectively, but tight integration of EQTEC Iberia’s biomass-gasification
technology with GE’s proven gas engines will provide high levels of emissions
performance, efficiency and economy.
Scheduled for completion by the end of 2014, the plant is being built by EQTEC
Iberia, part of Spanish holding company Ebioss Energy AD. It is the latest
development in Ebioss’ strategy to apply its Integrated Biomass Gasification
Cogeneration Power Plant (IBGPP) technology throughout Europe to help countries
reduce their dependence on foreign energy supplies and to increase the
proportion of energy from renewable sources. The country’s target is for 16
percent of its energy demand to be met by domestic renewable sources by 2020,
but at present more than 70 percent of its energy is from imported natural gas
and oil.
NASA Signs Agreement with German, Canadian Partners to Test Alternative Fuels
NASA has signed separate agreements with the German Aerospace Center (DLR) and
the National Research Council of Canada (NRC) to conduct a series of joint
flight tests to study the atmospheric effects of emissions from jet engines
burning alternative fuels.
The Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS II)
flights are set to begin May 7 and will be flown from NASA's Armstrong Flight
Research Center in Edwards, CA.
NASA's DC-8 and HU-25C Guardian, DLR's Falcon 20-E5, and NRC's CT-133 research
aircraft will conduct flight tests in which the DC-8's engines will burn a mix
of different fuel blends, while the Falcon and CT-133 measure emissions and
observe contrail formation.
ACCESS II is the latest in a series of ground and flight tests begun in 2009 to
study emissions and contrail formation from new blends of aviation fuels that
include biofuel from renewable sources. ACCESS-I testing, conducted in 2013,
indicated the biofuel blends tested may substantially reduce emissions of black
carbon, sulfates, and organics. ACCESS II will gather additional data, with an
emphasis on studying contrail formation.
Understanding the impacts of alternative fuel use in aviation could enable
widespread use of one or more substitutes to fossil fuels as these new fuels
become more readily available and cost competitive with conventional jet fuels.
