Hot Gas Filter Discussion Will Be Continued On July 2
Twelve experts weighed in on hot gas filtration options at the Power Conference
held by AFS in Charlotte eight weeks ago. This discussion will be continued on
July 2 at 10:00 a.m. The purpose will be to help decision makers determine the
options which are available and guide them to select the option which best fits
their unique needs.
The discussion will be a constructive review and new additions for the following
decision guide route map and summary
http://home.mcilvainecompany.com/images/Hot_Gas_Filter_Decision_Guide_April_30_2015.pdf
The decision guide starts with a clean slate. Why place the SCR ahead of the
particulate collector? Why use a rotary air heater with 10 percent leakage and a
discharge temperature of 320oF? Why use multiple devices for particulate
filtration, NOx reduction, and acid gas absorption? Why not combine all the
technologies in one device?
There are two options which are fully explored. One is the conventional option
which results in particulate filtration at 320oF. The other is the catalytic
filter with filtration at 850oF.
The 320oF option has two routes. One is to use a dry scrubber and fabric filter.
The other is to use an electrostatic precipitator. This decision is dependent on
the dust limit and the ability of the precipitator to meet it. It is dependent
on decisions about by-products. In fact there are many factors which need to be
considered. How will each option deal with mercury? Are there water use and
pollution concerns? What space is available? What is the age and condition of
the existing air pollution control system? As you can see, all these are
addressed in the guide. However, there was a difference of opinion on:
• Achieving 5 mg/Nm3 particulate continuously with a dry precipitator
• Bag designs for the filter alternative
• Media designs
• Fiber selection
• Method of cleaning
The greatest differences of opinion related to the 850oF option, should metallic
elements be used and followed by an SCR? Two variations are available: sintered
metal fibers and sintered powdered metal. Alternatively, why not use a ceramic
catalytic filter element? Both choices can be accompanied with DSI. If the
catalytic filter is the choice, then there are a number of related questions:
• Will the catalytic filter element prove as good in large coal-fired boiler
applications as it has in industrial boilers, glass plants, mining operations,
etc?
• Who will supply and guarantee the systems using catalytic filter elements?
• Who will supply the elements?
• Who will supply the catalysts and ceramic bundles?
One of the potential benefits of these expert discussions is the holistic
analysis. The question of pleated bags vs. tubular bags needs to take into
account the potential to vary the cleaning design. A more robust pulse cleaning
system and the pleated design may have to be matched against a less robust
cleaning design and the tubular bag.
There are billions of dollars being spent to improve the particulate removal
performance at coal-fired power plants in China, the U.S., South Africa, Europe,
Chile and even Russia. Cement plants and operators of industrial boilers are
also facing upgrades of their particulate removal systems at the same time they
are required to capture acid gases and reduce NOx. So this discussion is an
important one for combustor operators around the world.

$20 Billion Market for Air Pollution Solutions
Air polluters are increasingly seeking total solutions. The result is a market
for suppliers with double digit growth opportunity reaching $20 billion per year
by 2025. The scope includes initial design, installation, operational guidance
and maintenance programs. There are a number of drivers in this marketplace.
Driver Example
Complex systems with multiple control steps Coal-fired boilers, cement kilns and
chemical processes
Valuable final product recovery Precious metal mining
Valuable process product recovery Refinery catalyst, solvents in chemical and
surface treatment
Safety Explosive gases
Health Semiconductor toxic fumes
Potential for air pollution control system to negatively impact operations Many
industries
Lack of skilled personnel within the plant Continuous trend
Success of remote monitoring Applicable to all pollutants and operating
parameters
Ability of suppliers to provide a lower cost alternative Reduction of repairs,
downtime, energy consumption, etc.
The world’s information is increasing geometrically, whereas human capacity to
absorb it remains fixed. The result is that knowledge now resides in narrow
niches. The purchaser no longer has staff that can equal the knowledge provided
by the supplier who has the niche knowledge.
In the past, a plant only had to worry about stack opacity. The complexity of
the removal task has increased greatly with regulations on NOx, mercury, acid
gases and toxic metals. The choice of NOx removal equipment affects the
generation of SO3 which in turn necessitates an additional pollutant to remove.
The scrubbing option with the most environmental byproduct does not capture
mercury, whereas the option which does capture mercury creates solid waste
issues.
The result is that the initial design and operations is complex. Outsourcing is,
therefore, a cost effective alternative.

Renewable Energy Briefs
Mainstream Renewable Power Awarded 250 MW of Wind Energy Projects in South
Africa Government Tender
A consortium led by global wind and solar company Mainstream Renewable Power was
awarded Preferred Bidder status by the Department of Energy in South Africa for
two large-scale wind energy projects with a total generation capacity of 250
megawatts. The award was made under the fourth round of the South African
Government’s Renewable Energy Procurement Program and the two wind farms
represent an investment of approximately $469 million. The date for financial
close has not yet been released by the Department of Energy.
Mainstream has been awarded a total of 848 megawatts of wind and solar projects
under this program since the first award in 2011, which is more than any other
developer. In addition to the projects awarded today Mainstream is currently
constructing three wind farms in South Africa’s Northern Cape, totaling 360 MW,
which it was awarded under Round 3 of the program. Last year the company
delivered three wind and solar facilities into commercial operation in South
Africa under the first round of the program.
SCE Continues Encouraging Solar Development
Southern California Edison (SCE) continues to encourage and support the
development and interconnection of solar projects within its service territory.
SCE has about 125,000 rooftop solar systems installed in its territory, totaling
more than 1,000 megawatts. Those systems include residential and non-residential
installations, as well as some utility-owned projects. Nearly 600 megawatts are
from residential projects.
Adding to those totals, SCE recently announced that the California Public
Utilities Commission has approved 22 projects totaling 42.6 megawatts of direct
current power from the utility’s fourth solicitation to obtain electricity from
independent power producers as part of its Solar Photovoltaic Program (SPVP).
This Request for Offers is the fourth of five planned solicitations since the
program began in 2010. The solar program is just one of a set of programs used
by the utility to procure power from renewable energy generation projects. It is
designed to encourage energy production from rooftop-mounted solar photovoltaic
facilities sized between 1-2 megawatts, but allows for projects between 0.5-10
megawatts.
The rooftop projects selected are distributed throughout SCE's service territory
and were proposed by two different developers, Borrego and Sun Edison.
