Benefits of Sharing Air Pollution Information across Geographies and
Applications
Large power plants in the developed countries were the main purchasers of air
pollution control systems in the past. This is no longer the case.
Developing countries are the big spenders in the power plant sector. Other
industries such as cement, waste-to-energy, steel and oil and gas are stepping
up the investment to remove gas phase contaminants.
The innovations and insights are now scattered around the world. In order
to ensure that the value is shared, McIlvaine is taking several steps:
·
Strengthen the interface with Asian and African power plants who are making many
difficult decisions.
·
Expand coverage of all the industrial applications.
·
Facilitate the transfer of information from industry to industry.
Changes have been made to the McIlvaine webinar format as part of the new focus:
·
Organization is by pollutant with segmentation by industry rather than the
reverse.
·
Power point decision guides for various industry/pollutant combinations are
maintained and available for reference during the webinars.
·
The webinars are focused on helping end users make decisions using the guides.
·
End user participants can ask questions which will be addressed in the
discussion format.
·
Suppliers and various experts can submit information for consideration in the
guides and can debate or discuss options during the webinars.
·
The guides are displayed and continually updated on the Air Quality Decisions.
·
The webinars are free of charge to everyone. The decision guides and
access to the Air Quality Decisions website is free to end users but by
subscription only for others.
A webinar on February 11 will cover mercury control in all industries in all
countries. There will be seven slide decks available for reference and
display during the meeting:
·
Pulverized coal with wet scrubbers
·
Pulverized coal without wet scrubbers
·
Coal gasification and IGCC
·
Cement
·
Sewage sludge incineration
·
Waste-to-energy
·
Other including steel, taconite mining, etc.
Anyone can submit data for consideration over the next three weeks. End
users and subscribers can request copies of the draft slide decks in advance.
Activated carbon improvements are important and are options for all the
applications. Bromine injection to oxidize mercury also has widespread
application. Mercury absorber modules are now being used in power, sewage
sludge incineration and have potential for most applications.
The multi pollutant aspects of each application influence the mercury removal
choice. If wet scrubbers are used for acid gases, the bromine additive for
mercury oxidation is the likely first choice.
The mercury emission limit is a major consideration. Many industries in
many countries are not constrained. In others, the limit is 50 ug/Nm3.
This limit can often be met without special mercury reduction investment. The
U.S. has led the way with limits approaching 3 ug/Nm3. As a
result, many of the latest innovations have occurred here.
The decisions are influenced by the ultimate fate of the captured mercury.
One aspect is mercury re-emissions from scrubbers. Another is mercury in
gypsum and scrubber sludge. Dust with mercury laden activated carbon is
another challenge. There are some unique solutions which need further
investigation. Several waste-to-energy plants in Germany are utilizing
two-stage scrubbers. The first stage concentrates HCl and generates dirty
30 percent hydrochloric acid. The mercury is removed with ion exchange
resin. The clean acid is then sold.
This process opens up a brand new opportunity which is the rare earth and
precious metals recovery from flyash using acid leaching.
Combining emission sources is another solution. Municipal solid waste and
sewage sludge can be utilized in cement kilns and coal-fired power plants.
MSW gasification, cleanup and direct use as a turbine fuel is relatively costly.
On the other hand, using gasified dirty municipal waste as a reburn fuel in coal
fired boilers has several benefits. It replaces coal and reduces net
greenhouse gases. Injection above the primary firing zone reduces NOx.
The mercury in the gasified waste is removed along with the mercury in the coal
in the main air pollution control system.

McIlvaine Hot Topic Hours and Recordings
McIlvaine conducts periodic webinars which are in a discussion format and are
free of charge to all participants.
Format:
50-90 minute discussion using McIlvaine display material. The session will be
free of charge to all participants but registration is required.
Approach:
A summary with 50 or more slides covering the issues and options will be
displayed. The default coverage will be a brief review of the individual slides.
However it will be a discussion format with questions and comments encouraged.
The interactive index provides quick display
of any slide. Registrants will receive the
index to the slides in advance.
Value to purchasers and specifiers:
Your questions and interests will be prioritized in the discussion. The
complete summary will also be supplied to you subsequent to the meeting at no
charge.
Value to Suppliers:
You have the opportunity to provide data to be considered at no charge. If
you are also a subscriber, you will see the summaries in advance and be able to
shed light on issues and options not properly covered in the summary. If you are
a subscriber, you will have continuing yearly access to the summary and
intelligence system.
