ChemSep: Program - Overview

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.

Robust and Rapid Industrial Strength Solver

The new release features our most robust fastest simulator yet. ChemSep version 6 is significantly faster than earlier versions. Computation speed is high even when your simulation includes scores of different compounds. 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. The new version is more robust thanks to some novel convergence methods that now have been implemented. Together with our intuitive and easy to use interface you will solve your separations problem more rapidly than before.

Versatile and Customizable

Few column simulators run inside other simulation environments, but ChemSep does! Using CAPE-OPEN technology ChemSep can be run as a column model inside all major CAPE-OPEN compliant flowsheeting packages. CAPE-OPEN also means that ChemSep can use any CAPE-OPEN compliant thermodynamic package (including those of your favorite flowsheeting tool) and it allows any variable to be specified as in- or output variable. ChemSep offers a variety of ways to analyze simulation results, including a completely configurable mode that can export results to Excel in just the way you want.

Most In-depth Simulation Model

ChemSep includes more validated mass transfer coefficient, pressure drop, and capacity models than other programs. ChemSep's non-equilibrium model with integrated design method allows you to include nonequilibrium columns in flowsheets at the conceptual design stage. ChemSep now offers several vendor design methods and pressure drop models for both trayed and packed columns.
