Aspen BatchSep™

Conceptual design, analysis, and optimization of batch distillation processes

Aspen BatchSep is a comprehensive simulation tool for conceptual design, analysis, and optimization of batch distillation processes in chemicals, specialty chemicals, pharmaceuticals, food and beverage, and other industries. Aspen BatchSep is a core element of AspenTech’s aspenONE™ Process Engineering applications.

Features

  • Intuitive interface designed specifically for simulating batch distillation.
  • Interoperability of Aspen BatchSep models inside the industry-leading Aspen Plus® process simulation environment.
  • Best-in-class physical properties methods and data: Aspen Plus includes extensive databases of pure component and phase equilibrium data for chemicals such as electrolytes and complex intermediates. Ongoing collaboration with the US National Institute of Standards and Technology ensures easy access to the best available experimental data and methods.
  • Optimization tool enabling rigorous identification of optimum operating steps to minimize cycle time while maintaining operating and performance constraints.
  • Equation-oriented architecture allowing timely and robust dynamic simulation of complex columns.
  • Rigorous equipment modeling including flexible, configurable controller models, pressure drop correlations, multiphase, azeotropic, and reactive distillation, and options to start from empty or total reflux conditions.

Options

  • Aspen Plus: Aspen BatchSep models can be imported into Aspen Plus to simulate the batch distillation in context of the overall chemical process.
  • Aspen Simulation Workbook™: Enables easy development of Microsoft® Excel-based user interfaces to Aspen BatchSep, allowing broad deployment to casual users.
