I will design and simulate distillation columns and chemical processes in dwsim


About this gig
I am a Chemical/Process Engineer specialized in rigorous process simulation and distillation design using DWSIM (Aspen/HYSYS alternative).
My simulations are not academic exercises. They are built to support real industrial decisions such as equipment sizing, energy reduction, separation optimization, troubleshooting existing plants, and feasibility studies before construction.
Clients use my models to:
reduce energy consumption and operating costs
improve product purity and recovery
size columns, heat exchangers and pumps correctly
validate process modifications before implementation
avoid expensive design mistakes
What I can help you with:
Distillation column design and tuning
Multi-component separations
Reflux & reboiler optimization
Mass and energy balances
Reactor modeling (conversion or kinetic)
Full process flowsheets
Convergent DWSIM simulations
Engineering reports (PDF/Word)
What you will receive:
Clean DWSIM simulation file (.dwxmz)
Professional flowsheet
Product purity results
Mass & energy balance tables
Engineering summary report
This service is for chemical/process simulation only (not PLC or 3D modeling).
Please contact me before ordering to confirm requirements.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

FAQ
What software do you use?
I use DWSIM for rigorous process simulation. It is an engineering-grade alternative to Aspen HYSYS / Aspen Plus.
Do you only draw flowsheets or do real calculations?
I perform real thermodynamic and mass/energy balance calculations. Every flowsheet is fully simulated and converged, not just drawn.
What deliverables will I receive?
You will receive the DWSIM simulation file (.dwxmz), flowsheet, product compositions, mass & energy balances and a professional PDF/Word report.
Can you design distillation columns?
Yes. I design and optimize distillation systems including reflux tuning, reboiler duties, stage numbers, purity targets and energy consumption.
Can you model reactors and full process plants?
Yes. I can simulate reactors, heat exchangers, flash units, recycle loops and complete process plants.
Do you provide Aspen/HYSYS files?
No. I work in DWSIM. However, the methodology and results are equivalent and can be replicated in Aspen if needed.
Do you also provide CAD modeling or technical drawings?
Yes, I also offer CAD modeling and technical drawings. However, this gig is strictly focused on process simulation (DWSIM). CAD/P&ID/PFD drawing services are available in my separate gig.
Can you help with academic or university projects?
Yes. I can support both industrial and academic simulations with clear explanations and reports.
How fast can you deliver?
Small models: 1–2 days. Distillation systems: 2–3 days. Complex plants: 4–5 days. Faster delivery available as an extra.
