DWSIM distillation process simulation

A DWSIM process-simulation study of thermodynamics, column operation, energy use, and product purity in a selected binary distillation system.

  • DWSIM
  • Python
  • LibreOffice

Software compatibility

DWSIM only

The flowsheet and case files are delivered for the documented standard open-source DWSIM release. Aspen Plus, Aspen HYSYS, CHEMCAD, and PRO/II files are not included.

Project definition

Problem statement

Distillation results depend on vapour-liquid equilibrium, property method, stage count, feed condition, pressure, reflux, specifications, and convergence strategy.

Project objectives

  • Select and justify a thermodynamic property method for a prepared binary system.
  • Build a converged steady-state distillation flowsheet.
  • Close overall and component material and energy balances.
  • Compare reflux, stage count, feed stage, pressure, and product-purity cases.
  • Check rigorous results against shortcut or hand calculations.

System design

System modules

01

Thermodynamic setup

Defines compounds, property package, interaction data, units, and validity notes.

02

Flowsheet

Connects feed, column, condenser, reboiler, product, and optional recycle blocks.

03

Column specification

Sets stages, feed location, pressure, reflux, duties, and product targets.

04

Sensitivity study

Varies selected design and operating inputs while recording convergence.

05

Balance checker

Calculates component recovery, purity, duties, and material and energy residuals.

Methodology

System workflow

  1. 01
    Verify properties

    Basic phase-equilibrium behaviour is checked for the selected method and range.

  2. 02
    Build shortcut estimate

    A preliminary stage and reflux estimate provides a reference.

  3. 03
    Converge flowsheet

    The rigorous column reaches stable product and energy results.

  4. 04
    Run sensitivities

    Reflux, stage, feed, pressure, and purity cases are compared.

  5. 05
    Check balances

    Component and energy closure and result plausibility are documented.

Demonstration scenario

A binary feed is separated to specified top and bottom purities. The student justifies the property method, compares shortcut and rigorous stages, then measures how reflux and feed stage change reboiler duty, condenser duty, recovery, and convergence.

Engineering

Technical architecture

Environment
Native files for the documented standard open-source DWSIM release.
Thermodynamics
A justified activity-coefficient or equation-of-state method within a stated range.
Simulation
Steady-state equilibrium-stage column with explicit specifications and convergence settings.
Verification
Shortcut equations, independent balance tables, trend checks, and saved sensitivity cases.

Testing

Evaluation

Evaluation measures

  • Overall and component material-balance closure
  • Energy-balance closure
  • Product purity and recovery
  • Shortcut and rigorous-model comparison
  • Sensitivity to property method, reflux, stage count, feed stage, and pressure
  • Convergence reliability across cases

System boundaries

  • Only native DWSIM files are delivered.
  • The study uses a selected non-reacting binary system and steady-state equilibrium stages.
  • Hydraulics, tray or packing design, control, relief, mechanical design, hazards, and plant economics are outside the first scope.
  • The simulation is educational and not a plant design or operating instruction.
