    Simplify Creation of Distillation Schemes

    Aspen Distillation Synthesis enables rapid conceptual design of distillation schemes for the separation of chemical mixtures with non-ideal, vapor-liquid equilibrium. Use Aspen Distillation Synthesis to reveal the limits of feasible separations for individual columns and to design advanced distillation schemes for the separation of such mixtures.

    Build Distillation Models Directly in Aspen Plus

    Build conceptual design models with Aspen Plus, which contains six standard distillation column models.

    • Rigorous two-three phase fractionation (most popular)
    • Shortcut distillation rating and design
    • Rigorous counter-current extraction
    • And more!

    You also have the ability to import schemas directly from Aspen Distillation Synthesis.

    Get a More Detailed View of Your Distillation Columns

    Column Analysis in Aspen Plus allows you to immediately identify hydraulic issues (i.e. flooding and weeping) and understand the operating envelope for the entire column. Evaluate how modifications in packing and trays change the hydraulic operability of your columns. Downcomer choke flooding is now included in V10 to provide an indication of ineffective vapor disengagement at higher liquid flows.

    Highly Detailed Distillation Column Modeling

    Aspen Rate-Based Distillation Column Modeling extends Aspen Plus, our most popular RadFrac model, ensuring more accurate simulations and maximum reliability over a wider range of operating conditions.

    Distillation Modeling Specific to Batch Processes

    Use Aspen Batch Modeler in Aspen Plus for batch distillation modeling to predict and optimize cycle times, as well as pressure levels. Rigorous batch distillation modeling capabilities enable you to quickly and cost-effectively determine the optimum design and operating conditions, while maintaining the required product quality and purity, and ensuring safe operation.
    “Column Analysis in Aspen Plus helps Evonik to better understand the hydraulic performance of the tower with interactive functionality and visual depictions. With this deeper view, we can effectively troubleshoot, debottleneck, and determine the root cause of operations issues -- minimizing expensive, physical inspections of the column.”
