INTELLIGEN

- Version v9.0 - Designer Facilitates Modeling Software

0

SuperPro Designer facilitates modeling, evaluation and optimization of integrated processes in a wide range of industries (Pharmaceutical, Biotech, Specialty Chemical, Food, Consumer Goods, Mineral Processing, Microelectronics, Water Purification, Wastewater Treatment, Air Pollution Control, etc.). The combination of manufacturing and environmental operation models in the same package enables the user to concurrently design and evaluate manufacturing and end-of-pipe treatment processes and practice waste minimization via pollution prevention as well as pollution control.

SuperPro Designer is a valuable tool for engineers and scientists in process development, process engineering, and manufacturing. It is also a valuable tool for professionals dealing with environmental issues (e.g., wastewater treatment, air pollution control, waste minimization, pollution prevention). SuperPro provides under a single umbrella modeling of manufacturing and end-of-pipe treatment processes, project economic evaluation, and environmental impact assessment.

SuperPro Designer is available for the MS Windows 2000, XP, Vista and 7 platforms.. It requires a Pentium PC (> 800 MHz) with at least 128 MB of RAM, and 400 MB of free hard disk space.

Key Features of SuperPro Designer:

  • Models for over 140 unit procedures / operations.
  • Rigorous reactor modules.
  • Material and energy balances.
  • Extensive chemical component and mixture database.
  • Extensive equipment and resource databases.
  • Equipment sizing and costing.
  • Thorough process economics.
  • Scheduling of batch operations.
  • Throughput Analysis and Debottlenecking.
  • Resource (utilities, raw materials, and labor) tracking as a function of time.
  • Waste stream characterization.
  • Environmental impact assessment
  • OLE-2 support.
  • PFD customization through addition of your own graphics and text.
  • Compatibility with a variety of graphics, spreadsheet, and word processing packages.
  • Option to export PFDs in DXF format (for incorporation into AutoCAD) and in WMF format.

 

A brief description of the new features and capabilities in v9 follows below. For detailed information on the subject, please click here to download the 'SPDReadMe_v9.zip' file. It is a help-type of file (compiled HTML). You will need to unzip the downloaded file before you can run it. Then click on 'What's New in Version 9.0' (in the contents tree on the left) to see the detailed information on the new features in v9.0.  If you cannot see the contents of the file, please right-click on it, select 'Properties' and then click the 'Unblock' button.

Operation Scheduling Based on Finish Time

It is now possible to schedule operations based on their finish time. This is useful for pre-processing activities that must be completed before other operations that are on the critical path. The mode of scheduling (based on Start or Finish time) is selected using the “Start” or “Finish” option in the Schedule box (top of the dialog shown below). Alternatively, the same can be accomplished through the “Scheduling Dependency Link” drop-down menu at the bottom of the dialog.  In the past, users were forced to use negative “Time Shifts” in order to represent the equivalent of scheduling based on finish time.

Quick Scheduling of Slave Operations

In batch processing, it is common to have multiple operations running in parallel. A transfer-in operation in a vessel procedure that represents the eluant collection of a chromatography step is a typical example. The transfer-in operation has the same duration and starts at the same time as its corresponding elution operation. The “same duration” constraint is specified in SuperPro using the “Master-Slave Relationship” option for duration specification in the Oper. Cond’s tab. The “same start-time” constraint is specified in SuperPro through the “Scheduling” tab (see figure below). A new button has been added (Sync. With Master…) to expedite the “Same-Start-Time” specification for slave operations. Clicking on the highlighted button will directly set a 'start-to-start' relationship on the timing of this operation with respect to the (already assigned) master operation. Please note that this button is active for 'slave' operations only.

Independently Cycling Procedures

In the batch production of commodity biochemicals for which maintenance of batch integrity is not a requirement, it is common to have batch processing steps operating with a cycle time that is not related to the cycle time of the overall process (typically determined by the production fermentors). This is common with chromatography columns operating in SMB (simulated moving bed) mode, membrane filters that need periodic cleaning, rotary vacuum filters that need periodic pre-coating, etc. Basically, this is the case with cyclical units that macroscopically appear to function continuously in a batch process. This mode of operation for a procedure is specified by checking the “Cycles Independently of Main Recipe” button in the Procedure’s Data dialog (see figure below). More information on the subject can be found in the ReadMe files of the Citric Acid and Lysine examples of SuperPro as well as in the manual and help facility of the application.

Procedures that cycle independently display a clock icon on the left of their name (see figure below) that denotes their mode of operation. This icon is part of the procedure’s style and can be hidden by de-selecting the “Independent Cycle Sign” check box in the procedure’s icon style tab (right-click on the procedure’s icon and select Style \ Edit…).

Non-Ideal VLE Models Available Everywhere
 

Use of non-ideal models for VLE (vapor-liquid equilibrium) calculations is now available in all streams and unit procedures. In previous versions, that functionality was limited to few selected operations (e.g., flash, condensation, and rigorous distillation). Please note that the old short-cut method (based on normal boiling points) is still the default for most operations and streams. For streams, the rigorous option is specified through the Physical State tab of a stream’s dialog by checking the 'Overwrite' box for 'Physical State (PS) Calculation Options', selecting the 'Rigorous' option and clicking the 'Edit Rigorous Toolbox Options' button. That displays the window shown below that enables you to make the specification. It is possible to exclude certain components (e.g., non-volatile solids) from the VLE calculations by clicking the “Exclude Components From…” button and then identifying the non-volatile components. Please note that excluded components contribute to the energy balance calculations.

 

VLE options for procedures are specified by right-clicking on a procedure icon and selecting “Default PS Calc. Options…”. Please note that it is possible to specify the default rigorous VLE options at the flowsheet level by selecting “Edit \ Process Options \ Rigorous PS Calc. Toolbox…”. For more information on the subject, please consult the manual and the help facility of the application.
