August 29 DSUA, SOx-NOx Pre Conference Webinar
In the Sept 10-13 type frame there will be a
dry scrubber conference in the U.S and a SOx, NOx conference in India. Attendees at both conferences can benefit
from shared information on a continuing basis.
On August 29th at 10:AM central time,
there will be a preview of the DSUA conference and some insights for the
SOx NOx conference in India. Gerald
Hunt, DSUA president, will provide the DSUA preview. The question posed to
the audience will be how to leverage the conference and archives on a
continuing basis to assist in dry scrubber decision-making worldwide.

· Q. How will Sox-NOx 2019 benefit international
suppliers who want to partner with Indian companies?
· Q. Sox NOx 2019 attendance has been growing steadily
each year. What is your expectation for the quantity and quality of
information exchange this year?
· Q. Can you cite some specific examples of value which
will be provided this year?
Insights on the Indian market will be presented by Ravi
Krishnan of Krishnan Associates. McIlvaine is reporting programs for 100,000 MW of wet
limestone scrubbers which are well underway and 60,000 MW of dry scrubbers
for smaller and older plants which is just being initiated. Ravi will give
us his estimates. Ravi has already submitted a detailed analysis prepared
by Sumitomo SHI FW which shows that circulating fluid bed scrubbers have a
lower total cost of ownership than wet scrubbers for many Indian
applications. This analysis is posted in Coal Fired Power Plant Decisions (CFPPD) and will be displayed
during the webinar on the 29th.
Dr. Jianchun Wang
(Joe) will discuss the application of dry scrubbers in Chinese plants using
the data which is displayed in CFPPD. Longking is the largest supplier of
dry scrubbers worldwide.

consultants from Burns & McDonnell will be on the call. They have
prepared a list of some of the data which is needed. The obvious items on the list are fuel
and reagent quality, regulations, and plant operation characteristics. But
there are other items which may be overlooked. For example the water
required for semi dry scrubbing has to be low in TDS.
will consume 40 minutes. This leaves another 40 minutes for discussion on
how to leverage the world’s scrubber knowledge going forward. Relevant data
in CFPPD will be displayed. It will be permanently available free of charge
to operators (utilities, WTE, Steel, and other scrubber users). It will be
available free of charge to other webinar attendees and registrants to the
DSUA and SOx-NOx conferences for a period until Oct 1. This provides
everyone with access to the information.
One of the
items to be discussed will be the scheduling of webinars subsequent to the
two conferences. Another subject
will be the access to DSUA archives at a special price for
The concept of
Lowest Total Cost of Ownership Validation ( LTCOV) using the criminal prosecution format will be
debated. The supplier attempting to
validate the superiority of his product is the prosecutor. The competition
is the defendant. The customer is the jury. Following the prosecution
format the case revolves around the organized presentation of evidence.
This is provided in CFPPD as well as face to face discussions at
conferences. The individual case can be a system or a component such as
bags or fans. CFPPD provides coverage of all the combust, flow, and treat
processes associated with coal fired power plants around the world.
DSUA/SOx/NOx pre conference webinar will be held August 29 from 10:AM to
11:30 CDT. Attendees will have the opportunity to view the slides in
for the conference just send an email to Bob McIlvaine at firstname.lastname@example.org

is nothing which has impacted the market for combust, flow, and treat
equipment comparable to hydraulic fracturing and the resultant production
of inexpensive oil and gas. Tax cuts, deregulation and other factors
pale in comparison. In fact the loosening of regulations has had a
negative effect. For example a $700 million NOx control project for
BHE was canceled because of the reduction in requirements for NOx control
in the Western U.S where there is concern about visibility impairment.
U.S. was already the largest combined oil and gas producer prior to April
of this year when it also became the largest oil producer. Investment by
the major oil companies is having a significant impact. The majors

Bubble Bath vs Shower Approach to Scrubbing
large numbers of spray tower type flue gas desulfurization scrubbers
being built in India today. In the past two decades this spray
tower design was used for over 800,000 MW of capacity in China. This
approach to capturing SO2 could be likened to taking a
shower. A cascade of water sprays down from the shower head and washes away
the dirt. In the U.S. nearly half the installations use technology likened
to a bubble bath. The dirt impinges on the bubbles. Babcock & Wilcox
and Chiyoda have been the largest suppliers of the bubble bath systems.
Did China and
India make the right decision by opting for the shower design?
Possibly so but the decision making process was less than ideal. The bubble
bath type scrubbers were the early choice. Chemistry control problems
resulted in significant scaling. Utilities demanded a design with the
minimum amount of internals. Since the spray tower only has headers and
nozzles scale buildup was less. This open tower approach became the default
good chemistry control was perfected the bubble bath scrubbers were able to
operate with minimal maintenance. However, at this point in time there were
a large number of shower type scrubber suppliers who had invested
significantly to maximize the efficiency of the shower design. These
suppliers then became the licensors and partners of Chinese and Indian
companies. The early shower type scrubbers were less efficient but more
maintenance free than the bubble bath type. Is this still true?
appropriate to reopen the debate between these two types of scrubbers for
several reasons. One is the upgrading of shower type scrubbers. One of
the approaches offered by the shower scrubber vendors is to insert a bubble
bath type tray in the existing shower scrubber. The reason is that
efficiency can be improved without increasing the size of the
scrubber. Granted that there is a world of difference between upgrade
and greenfield economics, but why not thoroughly investigate the economics
of the two approaches through the range of new and upgrade requirements.
Andritz has been a shower type scrubber producer but has a new design
with a rod deck which uses the bubble bath approach.
There are also
criteria which are unique to one country. India has found that
rolling and welding scrubber shells at the job site as opposed to
shipping fabricated shells is more economic. With the smaller shells
required for the bubble bath approach, this may make a difference in the
evaluation. The bubble bath approach requires smaller pumps and larger
fans. For a typical 500 MW power plant a number of 50,000 gpm special pumps
are required with the shower approach. Only a few international
companies can build these large special pumps. The bubble bath approach
requires 25,000 gpm slurry pumps such as made by a larger number of
over these two approaches is being encouraged and reported in Coal Fired Power Plant Decisions.
This service is also providing a forum to evaluate circulating
dry scrubbers vs circulating fluidized bed vs spray dryer absorbers.
Subjects such as slurry, turbine bypass, anti-surge, and other
processes requiring valves are also analyzed. Membrane vs non-woven
laminates for filter media is an ongoing debate. Evaporation vs spray drier
approaches to zero liquid discharge is another example. Methods for
eliminating ash ponds and beneficiating ash are of high interest in
the U.S. A big challenge in China is to determine the best way to
upgrade sub critical and even supercritical to ultra-super critical
operation. For more information click on 44I
