OLI Version 12.7 simplifies chemistry data workflows with Excel data exchange

PARSIPPANY-TROY HILLS, N.J., Oct. 29, 2026 /PRNewswire/ -- OLI is making it easier for engineers to move between chemistry modeling and data analysis with the introduction of Microsoft Excel import and export in Version 12.7. The new functionality reduces manual data handling and the potential for transcription errors, while providing greater flexibility to evaluate and share results in Excel.

Much of the chemical data used in engineering analysis originates in spreadsheets, but transferring that data into OLI Studio has traditionally required manual entry. This adds an unnecessary step to the modeling workflow, taking time away from analysing the chemistry and interpreting the results.

With Version 12.7, users can create new analyses in OLI Studio directly from Excel or update existing OLI Studio projects as new sample data becomes available. Calculated results can then be returned to Excel, where teams can compare cases and incorporate their findings into existing reporting workflows.

Initially, the functionality supports selected objects in OLI Studio: Stream Analyzer and OLI Studio: ScaleChem, including water, brine, gas and oil analyses.

"Engineers need the freedom to work with their data in the applications that make sense for each stage of an analysis," said Lisa Williams, Chief Service Officer at OLI. "Our focus with Version 12.7 has been on making that process more straightforward, allowing users to spend less time preparing information and more time interpreting the chemistry and applying the results."

Version 12.7 also introduces Simple Membrane, a new process unit in OLI Flowsheet: ESP that extends modeling support for nanofiltration and other ion-selective membrane separations. The development addresses applications in water treatment and lithium recovery where conventional reverse osmosis models may not adequately represent the separation process.

Engineers can specify rejection rates for individual ions and define water recovery, with OLI calculating the resulting permeate and concentrate streams. The unit maintains electroneutrality and retains OLI's thermodynamic and thermophysical calculations, allowing engineers to assess properties including mineral scaling and osmotic pressure within the wider flowsheet.

Version 12.7 is available to download now.
