Gas Turbine Decisions Program
Gas Turbine Decisions based on the right facts
and factors
Mcilvaine has been analyzing gas turbine options
for air and water treatment plus combustion for
decades.
The Utility E-Alert plus the various
newsletters have continually reported on
innovations.
For more than a decade Mcilvaine published the
Gas Turbine and Combined Cycle Supplier Program.
An outgrowth of that service was Gas Turbine
Decisions.
This is a free service which can be
accessed at
http://www.mcilvainecompany.com/GTairTech/Subscriber/Default.htm
This service is being transformed in two ways.
·
Provide a system identifying the important facts
and factors shaping gas turbine air, water,
combustion decisions.
·
help suppliers utilize the various media to
provide validation of their value propositions.
Subsidiary child web covering Intake filters
An example of the approach is the gas turbine
intake filter.
Within Gas Turbine Decisions there is a
separate child web for intake filtration.
http://www.mcilvainecompany.com/gtairanalysis/Subscriber/Default.htmthis
This includes links to recorded webinars, white
papers, and analyses.
There is one analysis of all the various facts
and factors.
This is accessed from the left column
under Filters and Media.
It is an 84-slide compilation of
important facts and factors.

This website is in transition as additional data
is added.
Facts x relevant factors = forecasts = lowest
total cost of ownership = value proposition.
Forecasts include both technology and
revenues.
So, the split between revenues for pulsed
and static filters is directly proportional to
the cost of ownership.
The forecast for all suppliers x cost of
ownership advantage x validation success =
market share.
Each gas turbine filter niche whether it is just
an equipment application such as offshore rigs
or on shore plants in Saudi Arabia, or a product
such as pre filters needs to be addressed with
the fact, factor, and forecast analysis.
Helping Suppliers communicate their value
propositions based on facts and factors
Mcilvaine
is helping suppliers validate their value
proposition in a process similar to a civil
trial where the supplier is a litigant.
Step # 1 is to create a body of evidence which
can be made available to the jury.
Step # 2 is to use this body of evidence to
prepare a value proposition.
Step # 3 is to convince the jury.
A number of media and conferences are available
for the purpose of validating the value
proposition. Three examples are provided.
IFN is the top filter media publisher
INDA (association of non wovens) publishes
International Filtration News.
There is easy access to previous
articles.
Mcilvaine writes an article in each issue
on True Cost.
This is an ideal forum for analysis of new
filter media which can be applicable to many
applications beyond gas turbines.
The true cost of a gas turbine inlet filters can
be affected by a large number of factors.
These factors are not constants. They are
changing. The filter purchaser is challenged to
not only identify these factors, but also keep
up with the pace of change.
Studies show that turbine maintenance can be
reduced with
higher efficiency E12-U17. One study
showed that even if the cost of higher
efficiency filtration were four times higher
than lower efficiency, the true cost would be
lower.

Turbine filter seals and frames are also
important
In an article in Diesel and Gas Turbine World
Tim Nicholas, product manager of Parker Hannifin
gas turbine filter division wrote about filter
designs to meet the latest requirements.
The newer design turbines have special
needs.
Design features include advanced blade
aerodynamics, enhanced air-cooling flow,
improved design of hot gas path components to
reduce temperature and stress gradients and
upgraded thermal barrier coatings. The fine
tuning of these machines and the super alloys
they employ requires more rigorous protection
from the damage finer particulates and
contaminates.
The filter media is important but not the only
consideration. Edge seal technology such as that
used on Parker’s vCell filters incorporate
continuous hot-melt beads at the border of the
pleats to act as a secondary reinforcement seal
in high moisture environments.
When looking for a reliable filtration solution,
operators should also look for units that
include robust frames, the use of construction
materials that do not crack or become brittle
over time and media selection that is not prone
to sudden blockages and pressure spikes.

SpiderMaxx cassette filter for efficient
filtration of the finest particles
Freudenberg Filtration Technologies (FFT) said
its new spiderMaxx cassette filters for gas
turbines and compressors helps avoid costly
machine downtime and losses in efficiency.
The premium filtration performance is designed
to ensure clean air in gas turbines for power
plants and oil rigs as well as in compressors
for a range of industrial applications.
SpiderMaxx cassette filters offer this
performance over a long period of time and
reliability even at full load and during load
peaks. They are Efficient Particulate Air (EPA)
filter class and feature an increased dust
holding capacity and a service life that is
around 25% longer than the previous standard
cassette filter life, the company said.

Parker has lots of filters on offshore platforms
Parker Hannifin secured a contract to supply gas
turbine filtration systems for use aboard a
floating production storage and offloading
(FPSO) vessel planned for offshore Brazil.
Through its Gas Turbine Filtration division,
Parker Hannifin has long and successful
experience in providing air intake filtration
packages for use on FPSOs. Its close
relationship with major gas turbine OEMs often
makes it a preferred supplier for new projects,
the company said.
Gerald Woodward, division sales & marketing
manager, gas turbine filtration said Parker has
provided around 150 modular GT filtration units
with Static Offshore E12 air-inlet high velocity
worldwide,” We continue to develop and enhance
our filtration units to support the increasing
efficiency.”
KHL Group covers filters in multiple

Combined Cycle Journal
Three pillars for optimum filter selection
Michael Roesner of Donaldson provided insights
on filter selection.
Donaldson has developed a user-friendly filter
rating system that measures efficiency and two
other properties crucial to power output and
cost control.
Three performance factors important to selection
of the proper filter for your plant are
efficiency, watertightness, and, in
pulse-cleanable applications, pulse recovery
rate. Think of them as the key filtration
“pillars” that support optimal gas-turbine
operation. In most cases, all three performance
factors are important, but their ranking may
vary depending on the local environment and
operating conditions.
The Three Pillars can be described as follows:
Efficiency. The
proportion of particulates entrained in the
inlet air and captured by the filter is the most
widely recognized performance metric. Because
higher-efficiency filters have associated costs,
operators need to determine an efficiency rating
that delivers the best return on investment
(ROI).
Watertightness. In
humid or ocean-front locations, resistance to
moisture becomes a high priority. Salts and
other dissolved solids carried by water can be
highly corrosive and oftentimes more detrimental
than airborne contaminants.
Pulse recovery rate. How
readily filters regain peak performance after
pulsing is a third key concern. High pulse
recovery rises to top priority in desert or
arctic environments, where there is either
continual exposure to dust, snow, and ice
buildup, or potentially sudden episodes of heavy
loading.
Combined Cycle Journal covers filters from the
operator perspective.
This journal provides extensive coverage of gas
turbine user group activities and reports on
user experience and recommendations.
New Filter Media
Verdex introduces a new filter media
Verdex Technologies has developed and patented a
highly scalable and green nanofiber
manufacturing process called “melt-film
fibrillation” to produce advanced filtration
materials. The
process can produce materials with fibers
as small as 100 nm and submicron pore sizes. The
process bears some similarity with meltblown but
uses a shearing airflow to produce submicron
fibers from a thin film.
Unlike electrospinning it is entirely
solvent free and produces 3D fibers and a very
lofty material.
·
The median fiber size can be as low as 250 nm or
about ten times smaller than typical fibers from
meltblown media.
·
The fiber surface area is more than 100 times
greater than meltblown for particle deposition,
resulting in much higher filtration efficiency.
·
The fiber size is bimodal with the vast majority
of fibers below 500 nm and a small number of
larger fibers for structural integrity and
mechanical strength. A unique characteristic of
the material is the entanglement structure where
nanofibers get entangled within the larger
microfibers providing high mechanical strength
to the finished material.
·
Unlike microglass and ePTFE fibers, the Verdex
media is directionally homogeneous and is
equally strong in the machine and cross
directions.
·
The media produced has very high porosity (>
95%). This high porosity enhances dust holding
capacity and improves service life.
·
Virtually any type of thermoplastic polymer can
be fibrillated including biodegradable polymers.
This material offers high tortuosity and air
permeability and is capable of both depth and
surface filtration.
Comparison of Physical Characteristics
An extensive analysis of this media is contained
in a white paper found at
http://home.mcilvainecompany.com/images/Verdex_Technology_Overview.pdf
In future issues of the Alert we will be
covering the potential for this media for HEPA
level efficiency with lower pressure drop and
maintenance.
