Download ChemSep LITE

ChemSep is a column simulator for distillation, absorption, and extraction operations. It combines the classic equilibrium stage column model with a nonequilibrium (rate-based) column model in one easy and intuitive interface. Test-drive the equilibrium column model and convince yourself with the free ChemSep LITE with up to 40 components and 300 equilibrium stages using a database covering 400+ chemicals.

Industrial Strength Solver

The new release is our most robust and fastest simulator yet. Computation speed remains high even when including tens of compounds. With our intuitive and easy to use interface you will solve your separations problems more rapidly than ever before. ChemSep has been tested with many difficult industrial columns such as demethanizers, debutanizers, refluxed absorbers, azeotropic and extractive distillation; all run without requiring the user to make any initial guesses.

Versatile and Customizable

Few standalone column simulators run inside other simulation environments, but ChemSep does! Using CAPE-OPEN technology ChemSep can run as a column model inside all major compliant flowsheeting packages, including free packages like COCO. For this ChemSep has its own extensive set of thermodynamic and physical property packages but can also use any CAPE-OPEN compliant package and compounds, see our 2011 AIChE talk.

Comprehensive and In-depth Modelling

ChemSep rate-base model includes more validated mass transfer coefficient, pressure drop, and capacity models than any other program. The integrated design mode allows you to include nonequilibrium columns in flowsheets at the conceptual design stage, including industrial vendor design methods and pressure drop models for trayed and packed columns. It offers a wide variety of ways to analyze simulation results, such as McCabe-Thiele and operational diagrams, and includes a completely configurable export mode that write results to Excel in just the way you want.
