sors. " Dynamic modeling is the best
way to ensure the health and safety
of the compressors in a facility, but to
the typical process engineer, dynamic
modeling seems difficult and scary.
So we've developed an easier-to-use
dynamic model for this function, "
says Beck. " Our goal is to provide
more accessibility to difficult-to-use
tools by providing a number of different
templates and scenarios. "
The Activated Dynamics Analysis
automates dynamical modeling with
a single button click to speed model
setup and enable more process engineers
to perform compressor operability
screening (Figure 2).
Reliability and efficiency
Software that makes it easier for
operators and technicians to prioritize
actions is key to increasing
reliability and efficiency. " Processing
plants no longer have as many
skilled people as they used to, so

they are constantly faced with the
challenge of having to do more with
the people they do have, " notes
George Buckbee, general manager
at ExperTune, a Metso company
(Hartland, Wisc.; www.expertune.
com). " For this reason software solutions
that go beyond automated
monitoring to include automated
diagnostics and, more importantly,
automated prioritization and recommendations
are critical.
" There are so many issues at most
chemical plants that there's never
a chance to address everything, so
prioritization according to safety,
economic and technical factors is
of utmost importance, " Buckbee
explains. " If I can only work on one
thing today, what one thing should
it be? Our PlantTriage solution always
looks for that answer. "

Ensure your
piping integrity
In today's operating environment, it's more
important than ever that the piping within
your Mechanical Integrity Program complies
with standards such as API-570 and API-574.
Quest Integrity offers a comprehensive solution
for piping circuits using our proprietary,
ultrasonic-based intelligent pigging technology
combined with LifeQuest™ Fitness-for-Service
software.
Ensure your piping integrity by identifying
degradation before loss of containment occurs.

software performs continuous assessments
of the performance of
model predictive controls (MPC)
to improve the performance of the
whole control system, from advanced
control all the way down to the individual
instruments and valves. In
addition to a detailed assessment of
MPC performance, the latest version
now presents the results in a new,
more user-friendly browser interface
and allows users to drill down directly
from MPC monitoring to find
root causes that may be outside of
the MPC structure itself.
Buckbee adds that the latest version
can automatically generate
custom newsletters for individual
users. " For example, someone who's
responsible for controller tuning
gets a newsletter delivered to his
email box that may say: 'These five
loops need to be tuned. Here's what
the new tuning constants should
be.' This really streamlines the
work process and drives the work
directly to the individual who needs
to do it, " he says.
" We like to say that PlantTriage
is like having a 100-year-old, experienced
engineer who never sleeps.
