9.5.3 gPROMS
An advanced modeling environment for process industries is offered
by gPROMS (PSE, 2009), which provides advanced custom modeling
capabilities within a flowsheeting environment combined with an
object-oriented modeling language. The process modeling, process
simulation, and optimization capabilities of gPROMS are used to
generate accurate process behavior predictions and information for
decision support in product and process innovation, design, and
operation. Because gPROMS is a flowsheeting environment, the user
can optimize complex units within the context of an entire process.
The software employs synchronized graphical and text views, which
makes it easy to develop, maintain, and assure the quality of the
models, and archive them. It is capable of assessing all phases of the
process life cycle, from laboratory experimentation to process design
and detailed engineering to online operations.
For modeling problems and deriving solutions, the environment
provided by gPROMS ModelBuilder is employed. ModelBuilder is a
flexible environment in which engineering experts can perform custom
modeling, process engineers can generate graphical flowsheets, and
process operators can run “execution-only” routines. Figure 9.7 shows
an example user interface. In summary, gPROMS is an equation-
oriented modeling system used for building, validating, and executing
first-principles models within a flowsheeting framework.
