one group used a set of tools and
generated data, then passed it to
the next group, " he says. " But it
makes more sense for these separate
groups, who are really all working
to achieve the same goals, to use
the same simulation model and data.
Sharing the model means all the data
is consistent, so we are working toward
making sure the data from the
simulator can easily export into the
data standards that exist within other
engineering tools. "
For example, an engineering team
may build a model and then wrap an
Excel interface around it or send the
data to the supervisory control and
data acquisition (SCADA) system so
that operations and maintenance
staff can see what's going on and
perform their own engineering studies
without having to understand the
underlying engineering of simulation
or be trained on the simulator. " The
way this type of integration works
is that the engineer builds a model,
connects it to the OPC [open platform
communications],
and the
operations and
maintenance staff
can see the values
coming from
the simulator
and apply them
to performance
monitoring and
other tasks, " explains
Brown.

simulation and the plant's digital twin
can be used to pull all the disparate
systems together for a better view.
" There are a lot of different systems
managing separate things, so facilities
often have disparate data, systems
and business processes, which
means there are a lot of separate deFIGURE

the ability of simulators to address a variety of challenges. Here, Reactor

CONTROL VALVES FOR
ALL YOUR CORROSIVE APPLICATIONS
Collins plastic control valves are
highly responsive control valves
designed for use with corrosive
media and/or corrosive atmospheres.
Collins
valves feature all-plastic
construction with bodies in PVDF,
PP, PVC and Halar in various body
styles from 1/2 " - 2 " with Globe,
Angle or Corner configurations and
many trim sizes and materials.
Valves may be furnished without
positioner for ON-OFF applications.
Call for more information on our
plastic control valves.
