SYSTEM 7 Process Explorer®

The Evolution of a Revolution in Process Simulation Software™

The SYSTEM 7 Process Explorer® graphical user interface provides quick and efficient development and simulation of process flowsheets consisting of streams and unit operations. Output is made available in Process Notes™ for each stream and unit operation that can be docked as desired for ongoing analyzes. A detailed custom report can be exported to Microsoft Excel with all inputs and outputs available in Microsoft Access format.

Creating a Flowsheet: A flowsheet is created by opening a flowsheet and clicking on feed streams, product stream, and unit operation icons in the SpeedDraw Tools Pallet and clicking on the Process Explorer workspace. This process can be repeated until all of the desired feed streams, product streams and unit operations have been placed on the flowsheet. Then the stream drawing tool is selected to connect feed streams, product streams, and unit operations to complete the flowsheet development. Alternatively, the SpeedDraw ‘arrow’ icons can be clicked on to create a stream and the next unit operation or product stream as selected in the SpeedDraw Tools Pallet.

Running a Simulation: Once the flowsheet and data has been entered, select the Start icon to run the flowsheet simulation analysis. The streams in the flowsheet will change to green for gas, blue for liquid, and orange for multi-phase to indicate the calculated phase of each stream as a result of the simulation run. By moving the mouse pointer over any stream or unit operation, a Process Note appears with all important results displayed in miniature spreadsheet format.  The process notes disappear when the mouse is moved away.

Process Explorer Interface: The SpeedDraw Pallet provides all flowsheet development and navigation tools for quick data entry. Zoom In/Out and Zoom Window buttons are provides for adjusting the zoom level along with an indication button of % zoom which can also be clicked on to specify the precise zoom level. The top section of the SpeedDraw Pallet provides 8 directional arrows to create a stream from the currently highlighted unit operation to the unit operation selected in the pallet. Feed streams, product streams, and unit operations can also be created by selection in the pallet and then clicking on the Process Explorer graphical user interface. The stream tool allows for connecting intermediate and recycle streams to complete the flowsheet development. A freeform label with a border can be created for highlighting sections of a flowsheet, providing custom labeling, and displaying graphical bitmap images.

Thermophysical Properties: A process simulator is only as good as the thermophysical property data that it delivers. SYSTEM 7 Process Explorer provides the world’s leading thermophysical property data options by bundling the basic Dortmund Data Bank Software Package (DDBSP) with SYSTEM 7 along with full regression capabilities to accurately fit model parameters. For critically evaluated pure component data coverage, SYSTEM 7 provides the AIChE DIPPR® Database for selection of pure components and retrieval of the associated pure component properties. Psuedo Components can be specified by clicking on the Pseudo Component node in the tree view and entering its boiling point and specific gravity. Select the Property Slate – either ‘Oil’ or ‘Chemical’ to provide an accurate and complete thermodynamic specification for your simulation analyzes. The Property Slate selection determines all property routes/methods to provide the best possible accuracy for the system being analyzed. Highly tuned binary interaction parameters for the selected components will be automatically retrieved and utilized when available.
A matrix of coverage is shown for the liquid fugacity binary interaction parameters that have been loaded. If interaction coverage is not available, a warning is provided and binary parameters can be fitted from DDB experimental data and entered for either one time use or stored for automatic use in the future (requires the DDB VLE Data Bank).

With the same thermodynamic engine and methods used by the 8th Edition of the API Technical Data Book, SYSTEM 7 provides the recommended approach from today’s leading thermodynamic experts to help insure accurate results without the need to have a detailed knowledge in thermodynamics. Combined with the Dortmund Data Bank - SYSTEM 7 provides Intelligent Thermodynamics ™ to help insure accurate simulation results.

Advanced Features: With extensive customization capabilities through internal Function unit operations or external Excel calls, SYSTEM 7 provides a flexible, programmable process simulation environment. Access any stream or unit operation parameter directly through SYSTEM 7’s object-oriented architecture or use VB for Applications to build your own custom simulation solution in Excel.  Link your simulations with your plant data historian through Excel to provide online performance and analysis capabilities.

A Total Solution:  SYSTEM 7 Process Explorer includes Engineer’s Aide SiNET™ and CHEMPRO™ for simulation of pipeline networks, flare headers, and pressure relief valves with equipment sizing for pumps, fans, compressors, heat exchangers, tanks, vessels, etc to provide a total process engineering solution for your company. Improve both plant safety and profitability using SYSTEM 7’s field proven computational engines, intuitive interface design and industry standard thermophysical property data.
