SIM4ME Portal Excel integration with Simsci software simulation packages. Allows for bidirectional transfer of applicable variables between programs, and allows users without simulation experience the opportunity to interact with the simulator without necessitating prior knowledge or experience with the simulation software.

SIM4ME Portal

SIM4ME Portal is an integration application that facilitates the

powerful combination of SIMSCI-ESSCORs various process

simulation products (PRO/II, VISUAL FLOW, INPLANT, PIPEPHASE,

and ROMeo/ARPM) with Microsoft Excel.

PRO/II vs. PROVISION vs SIM4ME

PRO/II is the calculation engine

PROVISION is the graphical user interface

Makes PRO/II easy to use

Over time, older operating systems are no longer supported while

newer ones become supported

SIM4ME Portal is similar to PROVISION, but encompasses all

products

Common platform for multiple SimSci products

Steady State Simulator

No Time Dependent Phenomena

Exception: Depressuring Unit

Controllers and Instrumentation are Irrelevant

Simplify the Flowsheet by...

Grouping units if desired

Thermo Reset Unit


Distillation

Tray Numbering

Use Theoretical Trays (Stages)

Each stage is another flash calculation

Numbered from Top to Bottom

Condenser is always stage 1 if used

Even for subcooled condenser

Reboiler is always the last stage if used

Certain types add more than 1 effective stages

Model your reboiler based on how the return stream mixes back into

the column, not by what the actual type of reboiler it is

General Rule of Thumb when Converting Packing to Stages:

2 3 feet of packing per stage

Modern structured packing could be inches, so check with the

manufacturer

Tray Efficiency

Murphree

Vaporization

Equilibrium

Vapor leaving stage not at dew point

Can lead to mixed phase condenser product

Better to use overall efficiencies

Theoretical / Actual trays to carry out separation

Use different values in different column zones

Dont forget condenser and reboiler!

Typical Overall Efficiencies (%)

Deethanizers 60-65

C3 Splitters 95-100

Crude Units

Stripping Section 30

Flash Zone to Gas Oil 30-40

G.O. Draw to Diesel Draw 40-50

Diesel Draw to Kero Draw 45-55

Top Section of Column 55-65

Columns with reboilers and condensers 60-80

Pumparounds eliminate trays 20-25

Specifications and Variables

Specifications are constraints to be met by the column

Variables are calculated to meet specifications

Column always balances equations with unknowns (i.e. # of

specifications = # of variables)

To impose a specification, you must add a variable, other equations

and unknowns dont balance.

Example: Impose 2 product specifications by declaring reboiler and

condenser duties as variables

Improper Specifications

0% methane in crude column bottoms

Infinitely many solutions

300 lbmol/hr propylene in overhead

No solutions if column feed only has 250 lbmol/hr propylene

98% ethanol product

No solutions if water-ethanol azeotrope present

Keyword Files

Text version of PRO/II File

Significantly smaller size than *.prz files

Contains only the most important information for the simulation

Only shows items you have changed from default values

Keyword file runs very fast through batch mode

Useful for

Smaller size means less space when archiving simulation files or

sending via email

Running a large *.prz file in a shorter amount of time

Merging multiple *.prz files together (export *.prz files to keyword,

then copy/paste from 1 file to the other)

Troubleshoot input errors

Export *.prz file to keyword and reimport to clean simulation databases

Restore damaged *.prz files using input file in an output report

Exporting and Importing Keyword Files

To export a PRO/II file to keyword, go to File Export, then

choose Simulation Data to Keyword File

To import a keyword file to PRO/II,

go to File Import and select the
