Asian Coal-Fired Power Generators Will Spend Over $300 Million/yr. for Ultrapure
Water
By 2019 coal-fired power generators in Asia will be spending $342 million for
ultrapure water systems. This is up from $243 million in 2012. This
includes the ion-exchange or electrodeionization modules, ultrafiltration and
reverse osmosis, degasification membranes, metering pumps, treatment chemicals,
piping and all the associated valves. This does not include the valves in the
steam cycle. These forecasts are displayed in
McIlvaine publication, Ultrapure Water: World Market. (www.mcilvainecompany.com)
Asian expenditures will equal those of Europe/Africa and the Americas by 2019.
Many of the new power plants in Asia are of the supercritical design. They
require very high purity water due to the very high pressures and temperatures.
There is increased use of municipal wastewater and other low quality water
sources. This increases both the capital and consumable expenditures.
There are variations in contaminants such as silica in the water sources. So
each source has to be separately evaluated and the equipment and chemicals
tailored to that source.
Most of the investment is in the small fraction of fresh water which is added to
the recirculating system. The condensed steam can range from 99
percent of the total downward. The extreme case would be where all the
steam is being used for district heating and none is being returned. This
results in the need to purify large quantities of fresh water. However,
the quality requirement is not so high due to the fact that the contaminants are
not concentrating.
Condensate polishing is necessary due to corrosion of the piping and other
potential sources of contamination of the recirculating steam.

HCl Scrubbing and Rare Earth Recovery from Coal-Fired Power Plants and Gasifiers
are the Perfect Marriage
By using the hydrogen chloride in coal, the rare earths contained in it can be
extracted in what the McIlvaine Company believes to be simply the marriage of
two proven systems. This evaluation is contained in two McIlvaine
publications,
N043 Fossil and Nuclear Power Generation: World Analysis and Forecast
and
N027 FGD Market and Strategies.
The McIlvaine Company has been evaluating HCl scrubbers in coal-fired power
plants. It has also been evaluating the economics of rare earth and metals
recovery from the flyash produced by coal combustors and coal gasifiers. Using
the two technologies in combination has not been previously addressed. However,
McIlvaine concludes that they will unite in a perfect marriage which will reduce
electricity costs, reduce environmental emissions and produce very valuable
byproducts.
McIlvaine was involved in the original design of the HCl and SO2
scrubbing systems provided by United Engineers to Philadelphia Electric in the
1970s. Since that date, a number of companies have designed and installed
HCl scrubbing systems. Systems at waste-to-energy plants in Germany start
with a water scrubber which quickly absorbs HCl and allows the SO2 to
pass through. The recirculated scrubbing liquid quickly reaches 30 percent
hydrochloric acid. This percentage is maintained with a bleed stream of
acid which is then purified and sold.
McIlvaine began publishing a newsletter on coal gasification in 1979. In
the intervening decades, hundreds of gasifier systems have been installed around
the world. China has embarked on a program which would make coal gasification a
main source of gas and liquid fuels. There are several approaches to HCl
removal. The E gas system has a separate HCl scrubber. McIlvaine also
suggests that the GE particulate scrubber could be run at low ph
and produce hydrochloric acid. So a two stage scrubbing system is already
being used in the gasification process.
China is now mining flyash to recover large quantities of rare earth elements
and metals. One of the leaching methods is with hydrochloric acid. Why buy
hydrochloric acid when you can make it as part of the process? The
schematic below is a way to marry both processes.
February 2015 - Water Market Insights 136
This schematic provides the mixing of HCl and flyash in a system which
eliminates the first stage precipitator. It is therefore attractive for
old coal-fired power plants in the U.S. as well as for new coal-fired power
plants in China. It does incorporate a wet precipitator. Coincidently,
this is the latest trend in China for other reasons (to meet tough new
particulate standards).
Neumann Systems has a contract from DOE to extract REEs and metals
in conjunction with a scrubbing system which it is installing at Colorado
Springs Public Utilities. The proposed approach by McIlvaine differs by
proposing that rather than buy acid, the power plant can make it. The HCl
content does not have to be high. The first stage scrubber starts with
water and then reaches equilibrium with 30 percent dirty acid. A portion is bled
to maintain this percentage.
The advantages of using high chlorine coals would be that these coals are less
expensive and the byproduct sales volume of acid will be higher.
With an EPA grant Physical Sciences, Inc. (PSI) and the University of Kentucky
Center for Applied Energy Research (UK/CAER) investigated REE extraction from
flyash and concluded that the technology “has the potential to significantly
reduce U.S. dependency for Rare Earth Elements (REE) on foreign suppliers.”
The Chinese believe coal flyash is already a very attractive source for REEs and
are pursuing it aggressively. One reason is that the CO2 emissions
are 75 percent less than from extraction through mining. The coal is
already in a powdered condition. Reducing an ore to a powder takes lots of
energy.
This new approach would be more energy efficient than others and would be more
cost effective. Since it is the marriage of two proven processes, the
development effort will be minimal. The McIlvaine Company does not have
any patents or proprietary interest in the technology. It serves industry in a
consulting role part of which is to identify novel opportunities. For more
