changers every six months
or all of them every two
years or some of them now
and some of them later. It
may end up that they are
cleaning
exchangers
that
don't need it and neglecting
ones that do, which leads to
exchangers that fail or lose efFIGURE

confi guration platform, SPX's hybrid
heat exchanger is designed to operate
under harsh conditions where other heat
exchanger technologies can fail, have a
shorter operating lifetime, or reduce
operational efficiency
nology (Figure 2). On one side, the
plate is pressed into a tube-like form
so it can handle contaminants, and on
the clean side, a plate channel is used
to increase thermal efficiency. The unit
covers can easily be removed and the
" tube-side " plate can be high-pressure
cleaned. " This marrying of technologies
gives the benefit of the increased
thermal efficiency of plate technology
along with the 'tube' capability to handle
contaminants or solids, " he says.
And no matter the heat exchanger
type or design, Emerson Process Management
(Austin, Tex.; www.emersonprocess.com)
recently launched the
pre-engineered Heat Exchanger Monitoring
Solution that detects accelerated
fouling and identifies the best
cleaning time to optimize a facility's
energy usage, capacity and maintenance
costs. As part of Emerson's new
suite of Essential Asset Monitoring
applications, the heat exchanger solution
embeds process and exchanger
best practices into software that provides
automated, 24/7 monitoring
and allows maintenance personnel
to schedule an optimal time to clean
exchangers. As a result, optimal heat
transfer can be achieved, and facilities
can reduce energy and capacity loss
due to fouling by up to 10%.
" Fouling is the number one issue
associated with heat exchangers, "
says Nikki Bishop, senior application
consultant, R&D/engineering with
Emerson Process Management. " And
associated with fouling is knowing
when to clean exchangers and which
ones need to be cleaned. A facility may
have a schedule that cleans all the exCircle

ficiency and slow the plant down. "
To combat this loss of productivity
and efficiency due to fouling, Emerson
developed a method of intelligent
interpretation of data that allows temperature,
pressure, and flow around
the heat exchangers to be checked, and
based upon that, a fouling rate and fouling
percentage can be calculated. This
