ChemSep
ChemSep is a suite of programs for performing multicomponent separation process calculations on PC’s. But it is much more than that: it contains ChemProp which can visualize fluid phase equilibria as well as physical properties, ChemLib to manipulate pure component data, and a simple flowsheeting program to solve small flowsheets. It has lots of graphical output to quickly understand the simulation results but also facilitates tabular output that can be edited into the required format.

Chemsep что это за программа

Whether used stand-alone or embedded in a flowsheet, ChemSep provides you with a robust column simulator that does not require you to supply initial guesses. Our intuitive interface runs within all CAPE-OPEN compliant commercial process design software allowing a wide variety of column configurations and specifications. The easy to use interface enables you to solve your separations problems in minutes.

Models Actual Column Performance

ChemSep is a column simulator for distillation, absorption, and extraction operations. Choose the classic equilibrium stage column model and then switch to the nonequilibrium (rate-based) model for more accurate descriptions of actual column performance. ChemSep has its own libraries with an extensive set of capacity and mass transfer performance parameters for trays and packings. Together with the thermodynamic and physical property packages ChemSep offers a wide range of applications is covered.

Quick Engineering

Inspect the results of your column configuration instantaneously with predefined plots so that you can engineer the best line-up using rigorous simulations. Quickly find the specifications that deliver optimal column performance and use vendor tools to match capacity and required packed bed or trays to obtain the most economical solution. ChemSep can then directly export to requisition data sheets.

Industrial Strength Solver

ChemSep has been tested with many industrial columns such as demethanizers, debutanizers, refluxed absorbers, azeotropic and extractive distillation; all solve robustly without requiring the user to provide any initial guesses. Computation speed remains high even when including tens or hundreds of compounds. An extensive set of examples is available online.

Versatile and Customizable

Engineers do not have to worry about units conversions; they are built-in. Results can be exported into a range of formats including a spreadsheet layout that the you can design. Graphs can be stored and re-applied to each new simulation. Populate your toolbar with your favourite actions.

Comprehensive and In-depth Modelling

Simulate columns by means of efficiencies, or better, by means of detailed rate-based models for trays and packings to compute actual column performance. With ChemSep’s design mode the simulator runs automatically and column diameters are set by means of the specified fraction of flood. ChemSep has a large database with validated model parameters for all standard column internals including modern high capacity packings from Sulzer, Koch-Glitsch, Montz, and Raschig.

Test Drive for Free

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. Run ChemSep standalone or inside a flowsheet simulator.

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. New in release 8 is the capability to solve Dividing Wall Columns (DWC). As with all releases of ChemSep LITE this will be CAPE-OPEN compatible so you can model simple DWCs in your favorite flowsheet simulation package (the image below shows the DWC model being used in COCO). Just be aware that the DWC model in this release of LITE has some limitations: one wall only, and there is no heat transfer across the wall. New in release 8.2 is the ability to have more than one condenser or reboiler. Our industrial version will be able to handle multiple parallel walls which can be used to design more complex and higher energy saving DWC configurations. It also can be used to assess what maldistribution costs you in column performance.

Industrial Strength Solver

ChemSep 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 robustly 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, using their thermo and properties. However, ChemSep 7 now also exports its own extensive thermodynamic and physical property methods as a CAPE-OPEN Properties Package (CS/COPP), bringing various group contribution methods such as the Predictive SRK and the Universal Mixing Rule EOS methods that deploy modified UNIFAC to any compliant flowsheet.

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.
