A Molecular Knowledge Systems® Web Application
Exporting Physical Properties to AVEVA

The AVEVA process simulator provides a single platform for conceptual design, equipment optimization, and detailed engineering. Cranium and Synapse can generate input files for the AVEVA process simulator. These input files can contain both physical property data and parameters for physical property models. Once these files are generated, commands within the AVEVA process simulator can be used to read the contained physical property values into the simulator's databases.

Molecular Structure Entry

To generate an input file for a desired chemical, begin by drawing the chemical's molecular structure in the editor to the right. (Press the editor's demo button to view a short video explaining the editor's operation.)

Once you have drawn the molecular structure, press the 'Estimate' button. The entered structure will be sent to a WebServer Edition of Cranium running on the internet. Cranium will compile data, estimate properties, regress coefficients, and format results into the AVEVA input file shown below. (Note that the input file may take several seconds to generate depending upon the complexity of your molecular structure.)

Finally, press the 'download' button to save the exported contents into a file that can be imported into the AVEVA process simulator.

Exported AVEVA Input File

Use the 'download' button the text header below to save a file that can be imported into AVEVA. If you need to process a number of chemicals, you might want to download the Basic Edition of Cranium or Synapse. Both applications provide more functionality than that found on this webpage. (For example, click here to view documentation on the AVEVA Process Simulation export dialog.)

Please contact us if you encounter any problems or have any comments or suggestions.

Exported AVEVA Input File

The following presentation shows the commands to use from within the AVEVA Process Simulator to import the generated neutral file.

How It Works

The above structure editor converts the input molecular structure into a molfile string. This string is then combined with a request for an AVEVA input file and sent to a version of Cranium, Web Server Edition running on a Microsoft Azure virtual machine. Cranium processes the molfile, extracting substructures for group contribution techniques, and estimates the physical properties needed for the input file. The resulting input file is then sent back to this webpage for display.
