• The coal-fired boiler capacity in Europe and the U.S. will shrink but will
be more than offset by new Asian capacity.
• New plants will continue to select precipitators for more new capacity
than will choose fabric filters.
However the share for fabric filters will slowly increase.
• Some existing plants with precipitators which are not meeting emission
limits are installing bags within the existing precipitator shell.
• Dry scrubbing and Dry Sorbent Injection (DSI) are gaining market share
although wet limestone FGD is still the dominant choice.
• Catalytic ceramic filters are not expected to gain much penetration by
2020 but will potentially be the first choice for power plants in later
years.
•New technical developments are shaping the forecast and create substantial
unknowns.
Fabric filters can produce consistently low particulate emission rates. They
are not impacted by changes in the coal. Electrostatic precipitator
performance is affected by coal variations. Where mercury regulations are
stringent activated carbon injected ahead of the fabric filter can result in
higher removal rates than injection ahead of a precipitator.
Dry scrubbing involves less capital expense than limestone wet scrubbing.
Direct sorbent injection has very low capital expense other than the fabric
filter. However, reagent costs are high. Where stringent regulations are
forcing scrubber additions but boiler life is limited, dry methods are more
cost effective.
The fabric filter cake provides final absorption in dry scrubbing and DSI
systems. Presently the cleaning of filter bags is done to optimize
particulate removal. There is significant potential to optimize acid gas
removal as well as particulate with new cleaning technology. Ceramic filters
with embedded catalyst in conjunction with DSI are the lowest cost approach
to remove particulate, NOx and acid gas. This is because only one vessel
instead of three are needed. The approach has worked well with three meter
bags on applications with relatively low air volumes. Longer bags are now
being commercialized. This could lead to widespread use by coal fired
electric generators.
All the existing and proposed fabric filter installations on coal- fired
.boilers are tracked in
42EI Utility Tracking System.

Industrial Ventilation and Dust Collection Should Not Be Two Different Silos
Carefully engineered ductwork systems for frac sand plants (outdoors) have
the same needs for optimum hood designs and balanced flow ductwork (without
dampers) as industrial ventilation systems in foundries (indoors). Both have
the same stringent regulations regarding silica dust. Industrial ventilation
covers many types of air flow other than those ducted to a dust collector.
On the other hand the ventilation design used at the pickup points in a dust
collector system has a direct effect on the system cost and energy
consumption.
A well-designed hood utilizes only as much capture air as is needed. The
cost of the dust collector is a function of flow. So a hood that requires
twice as much capture air results in twice the system cost. A balanced
ductwork system maintains the best velocity. It is not so high as to cause
abrasion and excess energy consumption. It has to be high enough to insure
that material does not deposit in the ductwork. Dampers need to be avoided
because they cause turbulence and plugging. A correctly designed system uses
tapered ducting and a constant duct velocity throughout the system. Also
turbulence is avoided with gradual rather than abrupt changes in direction.

The concern for worker exposure to particulates is primarily focused on
individuals working in environments such as foundries and coal mines where
silica dust is generated. However, the concern for workers is just as great
in frac sand plants and facilities which create toxic metal dust. John Brown
of IAC-Intl in a recorded presentation linked from the McIlvaine Global
Decisions Orchard reviews the needs and solutions for frac sand plants. He
also references both primary and secondary lead plants where fine
particulate emission limits are much lower than they are for silica.
There are a number of companies who are eliminating the two silos. CECO has
acquired Kirk & Blum, a major ventilation contractor. It also acquired Flex-Kleen
and other companies making air pollution control equipment. Nederman
purchased MikroPul to complement its ventilation activities. In April 2018
it purchased Auburn FilterSense which makes triboelectric dust monitors
commonly described as broken bag detectors. This gives Nederman a tool by
which to remotely monitor the system operation and schedule bag replacement
as needed for environmental and other reasons.
3M has introduced a blue tooth enabled pressure sensor which is inexpensive
enough than it can be placed on every furnace filter. This technology has
even more justification for use in industrial ventilation systems. Those
systems dealing with toxic dusts have even more justification to install
continuous monitoring devices.
Companies such as IAC-Intl, Nederman and CECO have the opportunity to be
involved with industrial ventilation and dust control from the design and
construction through the entire life of the system. New analyzers, data
analytics and process management software make remote monitoring and O&M
support very valuable. The biggest profit potential is total solutions. The
supplier can provide a fixed price for O&M and replacement parts. With
skilled remote operators, the cost to the owner can be less than if the O&M
is handled in-house.

Dry Scrubber Design-Construct-Guide-Maintain Market to Reach 9.6 Billion
Dollars in 2020
Traditionally wet scrubbers have been used for removing SO2, HCl and other
acid gases. But recently owners have favored the newer dry scrubbing
technologies. The capital cost is much lower and there is no wastewater
disposal problem. The disadvantage is the higher use of reagents. However
with new monitoring and data analytics tools the reagent use can be
optimized and the total cost of acid gas capture reduced.
The big beneficiaries are the lime and other reagent suppliers. Their
revenues will reach $6.4 billion in 2010.

The total design-construct-guide-maintain market will exceed $9 billion in
2020. The largest purchase will be the reagent. Increasingly process
management software, wireless transmitters and data analytic will be
utilized to most efficiently operate these systems. Some combination of SO2,
HCl, SO3 and mercury often needs to be reduced. Multiple reagents, e.g.,
lime and activated carbon may be needed.
There are a range of dry scrubbing technologies being utilized. Dry sorbent
injection is the least capital intensive. Other technologies utilize
vessels. One vessel type is the spray drier, another is a fluidized bed. A
third design utilizes concurrent flow and recirculation of a portion of the
reagent.
Fabric filters are typically used to capture the reacted product as well as
the particulate.
Electrostatic precipitators are less frequently used due to their lower
absorption efficiency.
Applications include coal-fired boiler, cement, glass, biomass, steel and
waste-to-energy plants.
More details on the automation of these systems is found in N031 Industrial
IOT and Remote O&M.

New Baghouse for Algerian Cement Plant
The Aïn Touta Cement (SCIMAT) plant near Batna, Algeria, has spent US$10
million on a new filter. The investment is part of a group of improvements
intended to increase production at the unit in 2019, according to Le
Courrier d'Algérie newspaper. The company is also implementing a new
integrated administration system.
Upgrade to Cement Plant in Georgia
Mamuka Bakhtadz, the Prime Minister of Georgia, has officially opened a
US$100 million upgrade to HeidelbergCement’s Kaspi cement plant. Work on the
new dry production line at the site started in mid-2016. A filtration system
and equipment for continuous emission control were installed to allow for
online monitoring of the plant's dust and emission volumes. The project was
supported by the Georgian Co-Investment Fund and Honeywell Partners.
COAL-FIRED BOILERS
Wyoming Governor Evaluating Sites for Experimental Coal-fired Station
Wyoming Governor, Mark Gordon, is looking at least three potential sites for
the experimental coal-generating plant he wants to build in the state.
The Gillette News Record reports that Gordon told the Wyoming Press
Association Convention that the Integrated Test Center near Gillette is one
possibility. The other potential sites include the Dave Johnson Power Plant
in Converse County and the Jim Bridger Plant in Sweetwater County.
Gordon has asked state lawmakers for $10 million to build a 5-MW power plant
that would be capable of capturing at least 75 percent of its carbon
emissions.
The money would be used to leverage up to $40 million in federal grant
funding to supplement the work of the test center, a research facility at
the Dry Fork Station power plant.
India Releases Clean Air Plan
The Indian Government’s National Clean Air Program proposes a “tentative”
target of reducing PM2.5 and PM10 fine particle pollution by between 20 and
30 percent by 2024 compared to 2017 levels. The plan proposes increased air
quality monitoring and the development of city-specific action plans for 102
cities designated as in breach of air quality standards. However, even if
the reduction targets are met, India’s most polluted cities would still well
exceed World Health Organization standards. The plan provides for no binding
targets or enforcement mechanisms but notes there is a need to ensure
“stringent compliance” of all coal-fired power plants with new emission
standards by 2022. A study recently published in the medical journal The
Lancet estimates that air pollution in India caused up to 1.24 million
premature deaths in 2017.
Reconsideration of NESHAPs for Coal and Oil Fired Generating Units
The Environmental Protection Agency (EPA) is proposing a revision to its
response to the U.S. Supreme Court decision in Michigan v. EPA which held
that the EPA erred by not considering cost in its determination that
regulation under section 112 of the Clean Air Act (CAA) of hazardous air
pollutant (HAP) emissions from coal- and oil-fired electric utility steam
generating units (EGUs) is appropriate and necessary.
After considering the cost of compliance relative to the HAP benefits of
regulation, the EPA proposes to find that it is not "appropriate and
necessary" to regulate HAP emissions from coal- and oil-fired EGUs, thereby
reversing the Agency's prior conclusion under CAA Section 112(n)(1)(A) and
correcting flaws in the Agency's prior response to Michigan v. EPA.
We further propose that finalizing this new response to Michigan v. EPA will
not remove the Coal- and Oil-Fired EGU source category from the CAA Section
112(c) list of sources that must be regulated under CAA Section 112(d) and
will not affect the existing CAA Section 112(d) emissions standards that
regulate HAP emissions from coal- and oil-fired EGUs.
We are soliciting comment, however, on whether the EPA has the authority or
obligation to delist EGUs from CAA Section 112(c) and rescind (or to rescind
without delisting) the National Emission Standards for Hazardous Air
Pollutants (NESHAP) for Coal- and Oil-Fired EGUs, commonly known as the
Mercury and Air Toxics Standards (MATS).
The EPA is also proposing the results of the residual risk and technology
review (RTR) of the NESHAP that the Agency is required to conduct in
accordance with CAA Section 112. The results of the residual risk analysis
indicate that residual risks due to emissions of air toxics from this source
category are acceptable and that the current standards provide an ample
margin of safety to protect public health. No new developments in HAP
emission controls to achieve further cost-effective emissions reductions
were identified under the technology review.
Therefore, based on the results of these analyses and reviews, we are
proposing that no revisions to MATS are warranted.
Finally, the EPA is also taking comment on establishing a subcategory for
emissions of acid gas HAP from existing EGUs firing eastern bituminous coal
refuse.

METALS
Chengdu Changfeng Orders EAF Quantum Electric Arc Furnace and Ladle Furnace
from Primetals Technologies
Chinese steel producer Chengdu Changfeng Steel Group Co., Ltd. (Chengdu
Changfeng) placed an order with Primetals Technologies to supply an EAF
Quantum electric arc furnace and a ladle furnace for its plant in Dujiayan
city, Sichuan Province. This marks the 9th EAF Quantum for China. The EAF
Quantum furnace is designed to handle scrap steel of vary varied composition
and quality. The electrical energy requirement of the electric arc furnace
is extremely low because the scrap is preheated. This reduces both the
operating costs and the CO2 emissions. The twin ladle furnace sets the
desired steel grades and the correct casting temperature. The new furnaces
are scheduled to be commissioned in early 2020.
Chengdu Changfeng is a medium-sized state-owned enterprise based in Chengdu,
Sichuan Province. The company operates three steel branches, one oxygen
production company, and one mechanical manufacturing and processing company.
For the new EAF Quantum electric arc furnace and the twin ladle furnace,
Primetals Technologies will supply the complete mechanical and electrical
process equipment and the automation technology. This includes the automated
scrap yard management, the automated charging process, automation of the
oxygen injection and sand refilling, as well as the Level 2 automation which
makes the plant ready for Industry 4.0.
The EAF Quantum developed by Primetals Technologies combines proven elements
of shaft furnace technology with an innovative scrap charging process, an
efficient preheating system, a new tilting concept for the lower shell, and
an optimized tapping system. This all adds up to very short melting cycles.
The electricity consumption is considerably lower than that of a
conventional electric arc furnace. Together with the lower consumption of
electrodes and oxygen, this gives an overall advantage in the specific
conversion cost of around 20 percent. In comparison to conventional electric
arc furnaces, total CO2 emissions can also be reduced by up to 30 percent
per metric ton of crude steel. An integrated dedusting system with modern
automatic off gas control fulfills all environmental requirements.
Tenova LOI Thermprocess Will Supply a Large Aluminum Recycling Furnace to
Italian Company
Tenova LOI Thermprocess, supplier for custom-made heat treatment lines and
furnaces and specialist for recycling plants for contaminated aluminum
scrap, has received an important order from Fonderie Pandolfo, Italy, for
the delivery and installation of a Twin Chamber Melting Furnace TCF®.
Fonderie Pandolfo is the recycling and melting enterprise within the Panalco
Holding, specialized in processing of aluminum, mainly for extrusions. The
casted billets are mainly extruded in the extrusion shops of the main
European extruders.
Currently, over 60,000 tons of refined and recycled aluminum are molten and
cast into semi-products. Fonderie Pandolfo already operates a set of TCF®
and casting furnaces supplied by Tenova LOI Thermprocess in 2008. The new
installation will double the production rate, aiming to satisfy the
continuous market requests.
The TCF®, with a capacity of 65,000 tons/year, is designed for aluminum
scrap recycling. In order to cover a broad range of scrap and contamination
degree, the TCF® combines pre-treatment and melting in one furnace.
The beneficial TCF®-process relies on the efficient melting by limiting
dross formation due to pre-treatment, while the evolving Volatile Organic
Contents (VOCs) are combusted completely in the furnace to decrease the
overall energy consumption and fulfill the most restrictive environmental
regulations.
By combining regenerative air heating (CCR) and optimized thermal treatment
of the organic scrap components, this proven furnace technology reaches an
unmatched grade of energy and metal efficiency. A sophisticated automation
technology, applied by Tenova LOI Thermprocess with the aim to streamline a
fully automatic charging machine, increases efficiency further.
The scope of supply contains the turnkey-installation, including a
state-of-the-art flue gas treatment plant.
The TCF® is expected to go into operation at the end of 2019.
COMPANY NEWS
Nederman Year End Report is Cautiously Optimistic
Sven Kristensson, CEO of Nederman, provided the following comments in their
year-end report:
"After the challenging 3rd quarter when our US operations were hit by
production and distribution interruptions in the wake of Storm Florence and
the caution in China increased further, it is very satisfying that the
year's 4th quarter was strong. Incoming orders in the quarter grew to SEK
967.8 million (815.9), equivalent to a currency-neutral growth of 13.4
percent. Sales saw an even stronger development and amounted to SEK 1069.0
million (860.0) during the quarter, corresponding to a currency-neutral
growth of 19.4 percent. Adjusted operating profit increased to SEK 126.7m
(106.8).”
“The positive development during the final quarter of the year also means
that we see a strong development for the full year for 2018. Incoming orders
totaled SEK 3479.5 million (3,157.3), equivalent to a currency-neutral
growth of 7.4 percent. Sales amounted to SEK 3553.9 million (3148.5),
corresponding to a currency-neutral growth of 10.1 percent. The adjusted
operating profit rose to SEK 308.1 million (285.8), corresponding to an
adjusted operating margin of 8.7 percent (9.1). The slightly lower margin is
mainly explained by increasing investment in innovation and product
development. Earnings per share rose to SEK 5.79 (5.31). A dividend per
share of SEK 2.30 (2.00) is proposed.”
“During the quarter, Nederman acquired the Swiss group Luwa. This has
enabled us to strengthen our operations with a global market leader within
the air filtration field for the fiber and textile industries. Luwa's
significant market presence and its strong position in the fiber and textile
market which is an important market for Nederman, linked with our global
organization, will make the Nederman Group a more complete and attractive
partner for our customers, not lst in APAC where Luwa has a strong
position.”
“Just as during the 3rd quarter, Nederman Insight has continued to develop
positively. It is clear that our customers have a great need to establish,
with the help of Nederman Insight, a digital and online business with all
the benefits this provides. In 2018, Nederman Insight has taken the step
from idea to the establishment of significant business operations. We have
recently received orders for Insight solutions from customers in the wood
industry, foundries and from medical technology companies among others.
Nederman Insight as a whole is now approaching an annual turnover equivalent
to SEK 250 million. Although Nederman Insight already forms a significant
part of the Nederman Group, we are still only at the beginning of the
journey aimed at establishing Nederman as the obvious digital partner for
our customers.”
“Many of our markets are characterized by continued uncertainty. The risk of
trade conflicts and financial uncertainty means that decisions about major
investments are being delayed and that large projects are being postponed.
Despite these geopolitical challenges, our basic view is one of cautious
optimism. Environmental issues will continue to be important for our
customers and in 2018, we have strengthened our positions in several central
areas where we see that future growth will occur."
Donaldson Introduces Connected Technology
