Droughts and Water Shortage Is a Large Opportunity for Treatment and Flow
Providers
Many countries are facing major economic and political problems due to water
shortages. However, a combination of new technologies and more intelligent water
use can virtually eliminate the problem while boosting the economy. This
is the conclusion reached by the McIlvaine Company in
Air/Gas/Water/Fluid Treatment and Control: World Market. (www.mcilvainecompany.com)
Israel is the shining example of what can be done. Not only was water in short
supply a decade ago, but the available supply has shrunk further due to
droughts. However, Israel now has a water surplus and a booming economy.
The reason is it has embraced the latest desalination technologies and has
adopted a policy of water reuse. Eighty percent of the water now used in
Israeli cities is desalinated seawater. All municipal wastewater is
reused. Furthermore, Israel has led the world in drip irrigation.
The Amiad, Arkal and other filter technologies developed in Israel were
originally to filter water which has to move through tiny drip tubes and must be
free of contamination. So Israel is now the headquarters for a number of
international filtration companies. Amiad has developed into a $100
million corporation.
Desalination is decreasing in cost while the true cost of water from fresh
sources continues to rise. San Diego is installing a large desalination
system rather than rely on imported water. Water shortages in the
Southwest U.S. are causing municipalities to rethink pricing of water. In fact,
in some of the hardest hit communities, water prices are actually lower than in
some Eastern cities where water is plentiful. If cities reset prices to
levels based on demand, the cost of desalination will be comparatively
attractive in many areas of the U.S.
Treated municipal wastewater should replace fresh water at power plants.
Studies show that there are power plants in the proximity of nearly all large
municipal wastewater treatment plants. There are chemical and physical treatment
methods to make treated wastewater acceptable for all power plant requirements.
There are many technology advances which make desalination more cost effective.
Larger membrane modules with lower pressure drop are now available. The
recovery of reverse osmosis pump energy is another. Pre filters caused
problems at Tampa Bay. However, there are reliable inexpensive pre filters which
are available. Improvements in treatment chemicals keep the membrane
surfaces clean. Improved pumps and valves reduce maintenance expense. Cost
effective corrosion resistant materials are also now available.

Large Gas Turbine Aftermarket
Gas turbines are the leading choice for additional capacity in the U.S. and
Europe. As a result, in 2015 installed gas turbines will be capable of
generating 1.3 million MW of electricity. This large and growing installed
base has generated a substantial market for turbine components, steam cycle
components, intake air filters and treatment chemicals. A number of
McIlvaine publications forecast these expenditures and track the individual
plant activity.
The trend is away from peaking units and toward combined cycle operation.
One reason is the higher global warming potential of peaking units. The
aftermarket potential for a combined cycle plant is 20 percent higher than for a
peaking plant with the same electrical output. However, sales of some
products are lower. Air intake filters and gas turbine component
replacement sales are lower. However, steam turbine, HRSG, water filtration,
pump and valve replacement sales are higher.
Many new plants are opting for zero liquid discharge. There are two options.
One is dry cooling. Many Chinese plants are being equipped with air cooled
condensers. This is due to the water scarcity in the country. Some
new gas turbines in the U.S. are also opting for dry cooling. Most new
turbines in the arid southwest are being equipped with air cooled condensers.
Some new plants in areas where water is plentiful have also opted for dry
cooling. The reason is to fast track construction and avoid water permit
requirements.
A second option is to use wet cooling with water recycling. A bleed loop
is directed to a filtration and evaporation system. This results in pure
water recovery and waste which can be disposed as a solid. This option has
become quite popular. It can be combined with use of municipal wastewater
to eliminate any water withdrawal.
The frequent cycling of turbine units which are working in tandem with solar and
wind generation has resulted in a larger repair market than for units operating
in a steady state. Problems such as stellite delamination of valves have
been encountered.

“Gas Turbine Emission Control” Webinar on July 17th Will Focus On NOx,
CO and Toxics
This webinar will build on previous ones and a whole dedicated site
Gas Turbine
Emission Control - Continuous Analyses
Panelists will include:
Greg Holscher,
Sr. Applications Engineer, CERAM Environmental, Inc.
Joshua Gillespie,
EmeraChem
Thomas "Nathan" White,
Director, Business Development, SCR/DeNOx Catalyst & Technology,
Haldor Topsoe, Inc.
Glenn C. England,
Principal Consultant, Environ International Corporation
The webinar will include some brief presentations, but will evolve into a
collaborative discussion of the choices which turbine owners will have to make
to meet State and Federal emission limits and also ambient air quality limits
and tough limits to obtain construction permits. The unique challenges of
frequent cycling on both maintenance and exceedances also need to be considered.
NOx, CO, PM and VOCs all have to be considered. With the need
to introduce ammonia for NOx reduction, an additional potential
pollutant, NH3, needs to be considered. The choice of catalyst
is most difficult for units operating in a single cycle mode. The choice is
either high temperature catalyst or tempering air and lower temperature
catalyst. Each has advantages and disadvantages.
When both NOx and oxidation catalyst are incorporated, there are
options relative to location of each. Many plants are opting to convert
urea-to-ammonia on-site rather than use anhydrous or aqueous ammonia. There are
cost and safety considerations in making this choice.
These issues and others will be discussed. The webinar is free to power
plant operators. To join us next Thursday, July 17th at 10:00 a.m.
