Client Testimonials

“SIMSCI’s powerful tools have given solutions to many problems concerningoptimization, debottlenecking, energy savings, and new designs. The technolo-

gy is supported by truly excellent engineering services,” said EniChem’s corpo-

rate simulation coordinator. “EniChem wanted to find a standard that has an

open and common architecture across its diverse simulation applications and

also wanted an experienced vendor with a track record in more than just

steady-state flowsheeting. SIMSCI has the right strategic technology mix and a

vision of a Windows environment, as well as references in fluid flow, data rec-

onciliation, heat transfer, on-line optimization, and wastewater.”

4) Double-click on each external feed

stream to supply stream data

(flowrates, compositions, tempera-

ture, and pressure).

5) Double-click on each unit operation

icon in your flowsheet, and provide

the required process data (data

fields outlined in red). As you enter

process data, the data field border

changes color from red to blue.

6) That’s it! Once you have provided

all of the required data and no

longer see red-bordered fields, you

are ready to run your simulation.

Powerful, Easy to Use InterfaceThe PRO/II simulation program offers a

graphical environment with an easy-to-

use interactive interface, PROVISION. A

full-featured drawing utility incorporates

point-and-click and drag-and-drop func-

tionality for defining streams and unit

operations—so drawing process flow dia-

grams (PFDs) is simple.

PROVISION incorporates many built-in

Microsoft® standards, such as OLEAutomation, enabling you to quickly

transfer graphics and process data to

other Windows applications. You can eas-

ily configure the environment to suit your

preferences in many areas, such as units

of measure, thermodynamics, and unit

icon types. In addition, you can select

interactive or batch calculation control

and quickly review simulation results via

on-demand reports, plots, and tables.

PROVISION employs a novel approach to problem specification: an interac-

tive color-coded data entry and validation system guides you through simu-

lation setup and execution. The result: a remarkably easy-to-learn and easy-

to-use interface with visually enhanced program navigation.

Productivity–Enhancing ArchitecturePRO/II not only promotes ease-of-use but also provides the openness need-

ed to successfully transfer important data to other engineering programs.

Engineering workgroups can significantly improve productivity using this fea-

ture. The PRO/II OLE Automation layer provides access to practically any

piece of data in a simulation database. You can easily move data betweenPRO/II and Microsoft Excel or other OLE compliant applications through the

server interface. This powerful capability supports practically any engineering

workflow process.

Having a standard process engineering computing environment reduces soft-

ware learning curves, facilitates data transfer between applications, and increas-

es software usage. PRO/II provides an environment where engineers spend less

time simulating process problems and more time implementing process

improvements.

PRO/II Add-on ModulesThe PRO/II process simulation program offers you a number of optiona

modules for expanded functionality.

Interface Modules

• HTFS - The PRO/II-HTFS Interface automates the retrieval of stream property

data from a PRO/II database and creates an HTFS input file using the data.

• HTRI - The PRO/II-HTRI Interface retrieves data from a PRO/II database and

creates HTRI input files for the various HTRI programs. Stream property pro-

files from PRO/II thermophysical properties calculations are provided to

HTRI’s rigorous heat exchanger design programs.
