Continuous Analyses of Energy and Environmental Subjects Now Available
McIlvaine is launching a series of websites covering Industry Options.
Each contains one or more continuing analyses of the decisions which the
designer and operator have to make.
The websites already launched are:
·
Gas Turbine
Air Treatment – Continuous Analyses
·
Gas Turbine
Emission Control - Continuous Analyses
·
Dry
Scrubbing - Continuous Analyses
·
Mercury
Removal - Continuous Analyses
Websites under construction are:
·
Drinking Water Filtration - Continuous Analyses
·
Secondary Wastewater Treatment - Continuous Analyses
·
Steam Valves - Continuous Analyses
·
Wet Scrubber Design Options For Calcium Reagent
Access to each website is free to anyone. The intelligence system with all the
background information is also free with no password required. Additional
papers, presentations, etc. are invited. This includes text in other languages
as long as an English summary is included. A special emphasis will be given to
capturing the intelligence being generated in China.
The background information will be evaluated and Continuous Analyses prepared.
These continuous analyses will provide independent evaluation of the life cycle
costs and performance of all the various system and component options. Access to
these analyses will be free to owner/operators but will require a subscription
for others.
Suppliers can choose to have McIlvaine conduct an Application Audit. This audit
is a white paper with third party experts making independent evaluations. The
niche experts making these evaluations will be encouraged to focus on a very
narrow area to ensure that they have unsurpassed knowledge of the subject. The
Application Audits will be posted and free to anyone.
There will be periodic webinars on each subject. For example, there will be
several continuing analyses under Gas Turbine Emission Control. One will deal
with CEMS. A webinar will be held on April 17th to debate six
different approaches to measuring NH3. This follows previous webinars
on the subject and a feature article in Air Pollution Control magazine.
Two webinars relative to continuing analyses on mercury reduction are also
scheduled.
Webinars are free to plant owner/operators, but there is a charge for others.
Here is the near-term schedule:
Hot Topic
Hour Schedule
Dry Scrubbing Is The Topic Next Week.
On March 27th we will be comparing SDA, CFB and other CDS designs
including NID and GSA. We will be reviewing every aspect in which the designs
differ and discuss the merits of these differences.
Webinar registrants will have access to the information posted in the
intelligence system.
Dry
Scrubbing - Continuous Analyses
The format will be a series of questions which are first addressed by the
panelists and then the other participants. We have panelists who are third
party experts on dry scrubbers. They are:
One task will be to try to come to agreement relative to decisive classification
and the specific nomenclature. We have selected the first split at Chamber
vs. In-duct. Maybe better words are vessel and DSI but, in any case,
we will be trying to resolve the nomenclature issues in the webinar next week.
We will be focused on the comparison of the major alternatives. If the chamber
options are circulating dry scrubbers and SDA, how do they compare? Paul
Farber has contributed several good papers and will be a panelist next week.
Here is how we summarized one of his analyses of SDA and CDS:
·
SO2 Capture Capability - Advantage To CDS
·
Fuel Flexibility - Advantage To CDS
·
Load Flexibility - Advantage To SDA
·
Utilities Consumption - Slight Advantage To SDA
·
Waste Production - Advantage To SDA
There is still the need to breakdown CDS. What is the next level among CFB, GSA,
NID, etc? How many segments should be at one level and should there be
sub-segments?
We are looking at dual fluid nozzles vs. rotary atomizers, the size of NIDS
nozzles, air slides vs. screw conveyors and many other components. We are
focusing right now on the chamber segment but we already have a great deal of
DSI information on the site. This site is free to one and all although the
webinars and continuing analyses are more restricted. Let us know what you
think of this very different new approach.

Provide Your Input to Scrubber Design Options for Calcium Reagents
We are preparing a website on calcium based wet scrubbers similar to the one on
dry scrubbing. We will be looking at the four main components which are
gas (flow rate and distribution), liquid (droplet size and distribution), slurry
exposure (time and sequence) and droplet elimination.
There are three basic designs of limestone scrubbers. Here is a starting
point relative to assessing the advantages and disadvantages of each:

Within each category there are sub-categories. The tray design includes
perforated plates and several variations. One is called the rod deck and
was installed at Cilco Duck Creek Three and Northern States Power Sherburne.
Instead of round holes, there is the open area between parallel pipes about 2-e
inches in diameter.
There are significant variations among spray tower designs. For example, MHI has
a double contact with down flow followed by upflow. This design utilizes
rapid air flow. The air velocity is one of the big questions. It can
be 10-20 fps. At lower flows there is more retention time. At higher flows
there is more turbulence. It can be argued that the turbulence is more
important in the reaction than is the retention time. There is a tradeoff
between vessel size and pressure loss.
The role of mist eliminators cannot be underestimated. The question is when you
have higher turbulence do you need better mist elimination?
Efficiency, water (for cleaning) consumption, pressure loss and configuration
all need to be reviewed.
The role of nozzles varies greatly between the spray tower and other types. It
is critical in the spray tower design, but may be relatively unimportant in the
other designs.
We are now preparing the website for “Scrubber Design Options for Calcium
Reagents” and welcome input which will be relevant. Much of it will
come from our existing FGD & DeNOx Knowledge System which we have
been compiling since 1974. But we need to make use of the latest Insights
and look forward to your contribution.
FGD Revenues to Exceed $7.7 Billion in 2015
Sales of flue gas desulfurization (FGD) systems will exceed $7.7 billion in
2015. This is the latest forecast in FGD Market and Strategies published
by the McIlvaine Company. (www.mcilvainecompany.com)
The forecast includes both wet and dry scrubbing processes which remove sulfur
dioxide from power plant exhaust stacks.

Over 65 percent of the system revenues will be in East Asia. The majority of the
sales in this region will be to power plants in China. The revenues per MW
in China will be only 50 percent as large as the system revenues per MW in most
other countries. Therefore, the Chinese market share based on FGD MW will be in
excess of 80 percent of the total. Most of the Chinese sales will be
for new power plants, but there will also be some retrofits to old power plants
without FGD. China has more scrubbers than any other country, but also
more power plants without scrubbers than any other country.
There is competition among technologies. Wet scrubbers using limestone and
making wallboard quality gypsum as an end product will be the most popular. Dry
and semi-dry systems using lime will carve out a significant but minor share. In
the U.S., dry injection system revenues will be substantial. These lower capital
cost systems will be purchased for older power plants where the higher operating
cost is preferable. Many of these power plants may be retired in the next ten
years, so the expense over the remaining lifetime will be much less than if the
expected life were twenty-five years.

Top Ten Air and Water Monitoring Companies Had A 20 Percent Market Share Last
Year
The top ten companies in the air and water monitoring market had 2013 revenues
of $4.7 billion representing 20 percent of the $23 billion market. This ranking
analysis has just been posted to the McIlvaine report, Air & Water Pollution
Monitoring World Markets. (www.mcilvainecompany.com)
The market share is down slightly from a similar analysis last year. This is in
part due to the growth of Asian suppliers.

There are many thousands of companies participating in this market with sales of
less than $100 million. The total market includes those companies providing
periodic sampling. They often consist of a handful of people with a modest
investment in portable test equipment.
At the other end of the spectrum is Emerson which has complete automation
systems for air and water monitoring and control. It is also a major
supplier of combustion analyzers including oxygen and carbon monoxide. The
forecasts include distributed control systems and PLCs used in the monitoring
process. For this reason the top ten list includes not only Emerson but
Yokogawa, Siemens, Invensys and ABB.
Endress + Hauser and Thermo Fisher have the widest assortment of instruments,
but they are not at the top of the rankings because they do not supply extensive
software.
The automotive test system portion for Horiba is included because it is centered
on measuring the impurities in the gas discharged from engines. This is a
substantial portion of Horiba sales and, thus, elevates the company to the top
ten rankings.
There are several segments of the market growing at double-digit rates.
One is the market for continuous emission monitoring systems for gas turbines.
Another is the monitoring of shale gas and oil extraction and processing. The
highest rate of growth is for continuous emissions monitoring systems for
coal-fired boilers in China. Much of these revenues are captured by Chinese
companies even though the instruments are purchased internationally. This growth
has been another factor in the slight market share decline by the largest
companies.

Renewable Energy Briefs
Cape Wind Wins Major Legal Victories
In a set of major legal victories for the Federal Government and for Cape Wind,
United States District Judge Reggie B. Walton issued rulings against project
opponents in their four lawsuits that had challenged Cape Wind’s permitting
approval by the U.S. Department of Interior.
In his rulings, Judge Walton upheld the Department of the Interior’s review and
approval of Cape Wind, a thorough and comprehensive permitting process that took
10 years. The Court soundly rejected the plaintiffs’ request to vacate the
granting of the nation’s first offshore wind lease by the Department of the
Interior to Cape Wind.
Judge Walton rejected a long list of legal claims project opponents had raised,
including arguments over navigational safety, alternative locations, alternative
technologies, historic preservation, Native American artifacts, sea turtles, and
the adequacy of the project’s environmental impact statement and biological
opinions. In two narrow instances, Judge Walton has asked Federal agencies to
clarify its findings on whales and birds. The order indicates that the case is
administratively closed until the Court is provided with the clarifications.
Cape Wind expects these two compliance actions to be minor agency administrative
actions that will not impact Cape Wind’s financing schedule.
DTE Energy’s Northern California Biomass Plant Begins Operations
DTE Energy Services, Inc. (DTEES) has finished its construction project to
convert a shuttered coal-fired power plant at the Port of Stockton to operate on
biomass fuel.
The plant, known as Stockton Biomass, began commercial operations on February
21, 2014. It is selling its renewable power to PG&E Company to help it meet its
renewable energy requirement.
The plant will use about 320,000 tons of woody biomass fuel annually to generate
about 45 megawatts of power – enough electricity to meet the needs of 45,000
homes. The fuel primarily is derived from urban wood waste, tree trimmings and
agricultural processes.
DTEES, a subsidiary of DTE Energy, is headquartered in Ann Arbor, MI. It has
completed similar biomass conversions in Cassville, WI and Bakersfield, CA. The
company also operates biomass power plants in Woodland, CA and Mobile, AL.
Xcel Energy Announces Plan to Significantly Boost Solar Energy Resources Through
Large Scale Projects
Citing the advantage of adding more solar energy at a lower customer cost, Xcel
Energy submitted to state regulators a plan to add up to 150 megawatts of
large-scale solar resources in its Upper Midwest service territory by the end of
2016.
Xcel Energy is proposing that a significant portion of Minnesota’s solar
standard be met through large-scale projects, which are more efficient and less
expensive than rooftop solar and smaller distributed systems. The company
notified the Minnesota Public Utilities Commission of its intent to issue a
request for proposals by April 15, 2014, for large-scale solar projects totaling
up to 150 megawatts to be installed by December 31, 2016, prior to a reduction
in the federal Investment Tax Credit for solar.
The omnibus energy bill passed last spring by the Minnesota Legislature and
signed into law by Governor Mark Dayton requires investor-owned utilities to
acquire 1.5 percent of retail electricity sales from solar energy by 2020. Xcel
Energy estimates that it will need approximately 300 megawatts of solar capacity
to meet the standard.
DeNova Homes, PetersenDean and Canadian Solar Offer Solar as Standard in New
Lathrop, CA Home Community
DeNova Homes recently announced the future opening of the new contemporary
community of Edgewater at River Islands in Lathrop, CA, offering all new homes
with solar as standard, in a partnership with PetersenDean Roofing & Solar and
Canadian Solar.
While many new home communities offer solar as an option, Edgewater at River
Islands is one of the few that offer solar as a standard feature. The community,
which includes a variety of other eco-friendly attributes, has 92 lots that
provide 1.5 kW Canadian Solar Standard on every home backed by a 25-year
warranty. Buyers will have the option to upgrade to 3.0 kW or 6.0 kW, depending
on plans, elevations, orientations and available roof space. Federal tax credits
totaling about $2,500 are also available for most homeowners with solar roofing.
Additionally, estimated five-year savings can total up to $10,296.
A123 Energy Solutions Adds to Grid Storage Solution Deployments in China
A123 Energy Solutions announced the commissioning of a 500-kilowatt Grid Storage
Solution (GSS™) for Dongfang Electric Machinery Co., a manufacturer of power
generating equipment in China. The 500 kW, 125 kWh GSS is connected to the
microgrid at Dongfang Electric Machinery Co'sHangzhou facility and will be
performing renewable integration for the site, where it is co-located with wind,
PV, and conventional generation resources. This energy storage installation,
A123 Energy's second deployment in China, is a High Rate (HR) GSS and is not
containerized, but instead is housed in one of the site's existing buildings.
The HR GSS is well suited for accommodating fluctuations in variable energy
resources like wind or solar, and can be used to improve the efficiency of
traditional thermal generators as well. Operating worldwide in revenue service
since 2009, the HR GSS forms the bulk of the grid energy storage that A123
Energy Solutions has deployed to date, and performs in a variety of applications
including frequency regulation, reserve, ramp management, and T&D support.
