are some of the key new UniSim Design Suite
features and enhancements in this release.
Safety System Design Tools
With UniSim Design Suite R451, Honeywell is
enhancing the workflow and data transfer between
the pressure relief sizing product, UniSim PRS,
and the flare sizing and rating product, UniSim
Flare. This workflow is part of the larger scope of
development work on the safety system design
tool integration.
UniSim PRS exports an excel file, which contains
information per:
 Relief device: lists a data summary for all
scenarios applicable to a specific relief device
historical plant data. The generated data can be
used to tune scheduling and optimization
applications, through copy/paste functionality
and/or communications via OLE to excel.
The utility investigates a number of cases within
an operating range for each independent variable
and generates linear models with each dependent
variable. Once the vectors are generated, the
results can be visualized in plots, to compare how
well the linear models match the data. In cases of
non-linearity, the operational envelope can be
broken down into smaller ranges and different LP
vectors can be generated, to approximate linear
behavior.
With this development Honeywell is
commercializing and enhancing a Honeywell UOP
engineering tool. Although the original intent was
to better serve the refining market, this application
is very powerful and applicable to all other
markets.
 Project: lists the scenario which yields the
largest relief area for each device in a project
The data transferred, include:
 Non-scenario specific data: configuration
information (PRD and piping data)
 Scenario specific data: stream information (P, T,
F, and composition)
These data can now be imported into UniSim
Flare. This development eliminates tedious work
and potential errors with large volumes of data

Crude Assay Management
UniSim Design now links to Haverly H/CAMS, a
specialist 3rd party crude management software,
via a COM interface. Haverly library crude assays
Importing UniSim® PRS data into UniSim® Flare
can be imported under the UniSim Crude Manager
environment, where it is also possible to include
proprietary assays and import assays using the
crude assay import facility (which was introduced
with UniSim Design R450).
Haverly H/CAMS contains over 2000 assays:
