NOx Control for Gas Turbines is Hot Topic Hour on Thursday, February 14, 2013
With the Utility MACT and other issues discouraging any new coal-fired power
plants and causing the closure of many older coal-fired power plants as well as
the recent availability of natural gas, utilities are now looking to gas
turbines to fill the need for power. When considering a new gas turbine (GT)
installation or changing the operation cycle or fuel of an existing GT,
engineers and power plant operators must ask, “What is the most economical way
to meet the current and future NOx regulations?”
GT emissions are largely a function of turbine type, operating conditions and
fuel composition and these parameters along with site specific conditions will
determine the best NOx control scheme. Simple cycle and combined cycle gas
turbines typically require different approaches. Peaking turbines demand NOx
controls capable of a fast start-up while turbines operated continuously have
different issues related to load following. Whereas in the past gas turbines
primarily operated on pipeline quality natural gas and No. 2 diesel, concern
over greenhouse gas emissions and rising prices of premium quality gas fuels has
led to the use of poorer quality gases including fuels produced from coal,
biomass and wastes by gasification technologies. Power plants that use or may
consider using these alternative fuels must be sure that their NOx controls will
operate properly.
Available control technologies include Dry Low NOx (DLN) burners, water (or
steam) injection, add on SCR systems or a combination of these. Each of these
control methods has different effects on turbine power and efficiency, start-up
time, adaptability to load changes, reliability and operational life as well as
different operating temperatures, maintenance requirements and intervals,
parasitic power loss, capital and operating costs and effect on other pollutants
emitted.
The following speakers will address these issues related to the selection of a
NOx control scheme for specific gas turbines, discuss their experience with
specific NOx control technology and installations and describe any new
technologies being developed or tested for GT NOx control.
Thomas D. Martz, Senior Project Engineer Fossil Energy Research Corp., will
discuss “Gas Turbine SCR Performance Optimization and Management.” There are
several common causes of diminished gas turbine SCR performance, including poor
NH3/NOx distribution, flue gas bypass and catalyst deactivation. Fossil Energy
Research Corporation (FERCo) has developed instrumentation and methodologies to
help the gas turbine operator quickly identify and fix SCR performance problems.
There are also practical steps the operator can take to monitor and manage SCR
performance, such as monitoring catalyst activity and ammonia slip. Being
proactive with SCR optimization and management can extend catalyst life and help
the operator avoid unplanned and expensive outages due to NOx non-compliance.
Stewart Bible, Senior Manager Process Engineering at Fuel Tech, Inc.
Robert (Bob) McGinty Senior Manager, Business Development SCR NOx Control
Systems, Mitsubishi Power Systems Americas, Inc, will discuss fundamental SCR
system design, catalyst selection, ammonia vaporizing and distribution
technology, tempering air systems and maintenance concerns for reliable control
of NOx from simple cycle and combined cycle gas turbine applications and long
life of the NOx control systems.
Kelly M. Flannery, Chief Thermal Engineer, Andrew Heid - Emission Catalyst
Design Lead Engineer and Kristen Cooper - Simple Cycle Design Lead Engineer at
Vogt Power International, will present their three product lines for emissions
control from combustion turbine exhaust: 1) Simple Cycle Exhaust Catalyst
System, 2) Combined Cycle HRSG Installation with Catalyst and 3) Steam Injection
for NOx Control.

Sales of New Precipitator Systems Will Exceed $5.6 Billion in Asia in 2013
Sales of new precipitator systems will exceed $5.6 billion in Asia in 2013. This
is the latest conclusion in Electrostatic Precipitators World Markets published
by the McIlvaine Company as a continually updated comprehensive online analysis.

The Asian market will far exceed the rest of the world. This is due in large
part to new precipitator sales to power plants in India and China. Replacement
of existing precipitators with new precipitators will be relatively modest.
In contrast, the replacement market is a much bigger percentage of the revenue
in the U.S. and Europe. One reason is the preference for fabric filters. This
trend is also starting in Asia. Chinese power plants are already anticipating
the need to install fabric filters to meet tough particulate regulations.
The aftermarket including repair parts, maintenance and services adds another $5
billion in yearly revenues. Until recently, the aftermarket in the U.S. and
Europe was much bigger than in Asia. But this is starting to change for two
reasons:
• Tougher regulations are requiring more maintenance
• The Asian installed basis now closer to the ROW
In the U.S. a number of power plant precipitators will be taken out of service
and the entire facility retired. So, in a period when the U.S. will lose 40,000
MW of existing precipitators, China will add 400,000 MW.

Control requirements for ultrapure water are demanding due to the need to
integrate a number of purification processes. The need to reduce contamination
to very low levels challenges the instrument suppliers.
In the semiconductor industry, ultrapure water takes the following path:
• Pretreatment
• Make-up
• Polishing
• Distribution Systems
• Recovery
• Reuse & Reclaim.
The steps to reuse and reclaim have developed over the last decade and add to
the control complexity. For example, consider just the treatment of Copper CMP
Wastewater. One of the turnkey solutions suppliers is Ovivo. Their process adds
a catalyst to copper waste utilizing the oxidant present to form a strong
oxidizer. The strong oxidizer breaks down the complexed copper and reduces the
wastewater’s organic concentration. Copper can then be precipitated as copper
hydroxide and removed with the slurry particles. Ovivo’s advanced oxidation
process is notable for:
• Lowest chemical consumption
• Achieving stringent wastewater discharge requirements
• Reducing not only copper, but also organics
Preventive maintenance requirements are often included in the automation system.
The reverse osmosis system is maintenance prone. The filters need to be cleaned
or replaced on a regular basis. The differential measurement can be used to
determine at which point the filters need to be cleaned or replaced. Typically,
a pressure switch is used in these applications; however, problems can arise
from vibration and pressure surges in the system.
One semiconductor facility switched to a Yokogawa EJA transmitter which produced
consistently accurate output, resulting in better process efficiency and less
maintenance downtime.
Ultrapure water control and instrumentation requirements for coal-fired power
plants have become more challenging with the advent of ultra-supercritical
designs, the high pressures and high temperatures along with the increased water
purity requirements.

Renewable Energy Around the World
As 2012 drew to a close many areas of the world had made good progress
increasing their use of renewable energy. McIlvaine reports these advances in
Renewable Energy Projects and Update.
FERC Report Shows Renewable Energy Accounts for 46.22 Percent of New Electric
Generation in 2012
The American Council on Renewable Energy (ACORE) applauds the renewable energy
industry for installing 46.22 percent of new electrical generating capacity
brought online since the beginning of 2012. According to a recently released
report from the Federal Energy Regulatory Commission (FERC), wind, solar,
biomass, geothermal, and hydropower accounted for a majority of the new
renewable energy projects producing clean electricity in 2012, and are now
responsible for more than 14.9 percent of total operating generating capacity in
the U.S.
As ACORE’s post-election survey demonstrated, renewable energy has strong public
support in America’s battleground states. Majorities in all four swing states
polled after the election showed significant support for continued government
investment in clean energy. Vice Admiral Dennis McGinn ended by saying, “America
has watched the prices of electricity generated by renewable energy decrease as
the political opposition against the industry has increased. With continued
support, this industry has shown that renewable energy is not just the energy
source of the future — it’s the energy source of today, diversifying our energy
mix and creating a more secure America.”
EU Greenhouse Gases in 2011: More Countries on Track to Meet Kyoto Targets,
Emissions Fall 2.5 Percent
Emissions of greenhouse gases in the European Union (EU) fell on average by 2.5
percent from 2010 to 2011, although several countries increased emissions.
Almost all European countries are individually on track towards their
commitments under the Kyoto Protocol compared to last year, according to two
reports published by the European Environment Agency (EEA).
According to EEA’s estimates, the largest relative emissions decreases from 2010
to 2011 were registered in countries with small to medium shares of total EU
greenhouse gas emissions: 13 percent in Cyprus followed by 8 percent in Belgium,
Finland and Denmark. The United Kingdom made the biggest emission cuts in
absolute terms, with a reduction of 36 million tons CO2 equivalent (Mt CO2 eq.)
in 2011, or 6 percent. This was followed by France (24 Mt CO2 eq., 5 percent)
and Germany (17 Mt CO2 eq., 2 percent).
Nine EU Member States increased emissions between 2010 and 2011. Bulgaria
increased emissions by 11 percent, while Lithuania increased by 3 percent and
Romanian emissions rose by 2 percent. However, these countries have made some of
the deepest cuts in emissions overall since 1990.
Although economic factors played a part in certain countries, it is notable that
the EU economy overall grew by 1.5 percent while emissions fell by 2.5 percent.
Most of the countries registering the deepest cuts in emissions had positive
growth in 2011.
A warm winter in most countries was a key factor in cutting emissions in 2011,
as the demand for fossil fuels for heating was lower than in previous years. The
residential and commercial sector —largely outside the scope of the EU emissions
trading system (EU ETS) — contributed most to lower emissions in the European
Union.
German Businesses and Households Accounted for 95 Percent of Total German
Climate Finance in 2010
A new study released by Climate Policy Initiative (CPI) provides the first
comprehensive overview of how German businesses, households, and government
finance renewable energy and energy efficiency. The report “The German Landscape
of Climate Finance” shows that Germany invested 1.5 percent of GDP in 2010, or
€37 billion, in measures to reduce the impact of climate change.
Private capital is of great importance to climate investments in Germany. In
2010, the majority (€22 billion) of climate finance came from corporate
investors across all sectors of the economy, including farmers, energy
utilities, and industrial and commercial enterprises. Private households
invested a significant €14 billion.
According to CPI, government incentives play a major role in unlocking private
climate finance in Germany. Almost half of all private climate investments
(€16.5 billion) were supported by low-interest loans from public banks, such as
KfW or Rentenbank.
“The task of the government is to create the conditions for businesses and
households to invest in renewable energy and energy efficiency. And indeed,
government-backed low-interest loans and policies such as the feed-in-tariff
seem to have played an important role in encouraging these private investments,”
says Barbara Buchner, Director, CPI Europe.
The German government has committed to reduce greenhouse gas emissions by 80-95
percent by 2050 and phase out nuclear energy by 2022. These objectives have
positioned Germany as a world leader in national climate mitigation efforts, but
also require significant investments that cannot be provided by public funds
alone. Therefore, a high share of private finance can be regarded as a positive
signal for Germany’s low-carbon strategy.
The report also looked at how climate finance is used in Germany, and presents
figures for total capital investments for renewable energy and incremental
investments for energy efficiency. Renewable energy generation accounted for the
bulk of Germany’s climate investment in 2010, with €26.6 billion. Small-scale
renewable energy projects, such as residential solar photovoltaic installations,
represented 75 percent of all investment in renewable energy, while large-scale
projects accounted for the remaining 25 percent. Energy efficiency investments
amounted to €7.2 billion, and €3.3 billion went into other climate specific
investments.
IEA Applauds Korea’s Green Growth Strategy
In an in-depth review of Korea’s energy policies released, the International
Energy Agency applauds the country’s long-term commitment to green growth and
achieving a low-carbon future but also sounded notes of caution regarding some
elements of existing energy strategy.
Korea, the world’s thirteenth-largest economy and the seventh-largest exporter,
is an energy-intensive nation. In 2008, it adopted a long-term “green growth”
strategy to foster economic development by means of low-carbon technologies and
clean energy; since then, the government has implemented many policies to
support these goals.
A key element of Korea’s long-term strategy is a government commitment to reduce
its greenhouse gas (GHG) emissions by 30 percent compared to its business as
usual (BAU) case by 2020. In 2012, in order to achieve this target, Korea
announced details of an emissions-trading scheme — the first of its kind in Asia
— which will be implemented in 2015.
Ex-Im Bank Authorizes $150 Million in Export Financing for Energy Projects in
Latin America
More than a $150 million worth of American-made energy equipment will head to
Uruguay and Mexico because of transactions approved this week by the
Export-Import Bank of the U.S. (Ex-Im Bank). The bank approved a $78.6 million
direct loan to Abengoa, a company in Seville, Spain, that applies technology
solutions for sustainable development in the energy and environment sectors. The
Bank also approved a $73.6 million direct loan to Palmatir S.A., a 50 MW wind
farm in Cuchilla de Peralta, Uruguay, which is owned by Abengoa. Approximately
510 American jobs will be supported from these two transactions.
The Middle East will Soon Lead the World in Developing Sustainable Energy, Says
an Author of World Energy Council Report
The Middle East may soon overtake other nations and become the global role model
in developing sustainable energy, according to an author of a new report
released by the World Energy Council and Oliver Wyman at the COP 18 United
Nations Climate Change Conference in Doha, Qatar. The World Energy Trilemma is
the struggle that governments face in providing energy that is secure,
affordable, and environmentally-sound.
A World Energy Council/Oliver Wyman Energy Sustainability Index within the
report that ranks 92 countries' energy systems shows that the energy systems of
the United Arab Emirates, Qatar, Saudi Arabia, and Kuwait lag behind nearly half
of those in the rest of the world in terms of their ability to provide
sustainable energy.
But it also demonstrates why the Middle East may soon emerge the world’s leader
in this area: The region is adopting many of the practical and interconnected
steps required to achieve sustainable energy faster than many other nations can.
"The Middle East is well-positioned to take the lead in the global sustainable
energy race that is about to reshape the world’s energy landscape,” says Oliver
Wyman partner and a report author Mark Robson. "Most governments in the Middle
East have set out aggressive plans for reaching sustainable energy goals over
the next eight to 18 years and they have the political leadership and financial
resources to achieve them."
