I need a Pakistan-based chemical engineer who can jump straight into Aspen HYSYS and build a reliable simulation model for an ongoing process-engineering and product-development study. The work centres on a biochemical route, so experience that spans classical process design as well as biochemical engineering quirks will be valuable. Here’s what I expect: • A clean, well-structured HYSYS file (.hsc) with all units, streams, and thermodynamic packages properly defined. • Stream and equipment sizing reports that can be lifted directly into the wider project documentation. • A brief technical note (2–3 pages) that explains key assumptions, convergence strategy, and any sensitivity checks carried out. Accuracy, clear documentation, and adherence to good simulation practice are far more important to me than speed. If you have handled similar simulation and modeling tasks in Aspen HYSYS before, let me know—screenshots or sample files will help me gauge fit quickly.

I am a Pakistan-based chemical engineer with significant experience in Aspen HYSYS, specializing in both classical process design and biochemical process simulation, including fermentation-based routes, enzyme-catalyzed systems, and separation of bio-based products. I understand the importance of accurate thermodynamic package selection (e.g., NRTL for aqueous organics, custom components for biochemical species) and robust convergence strategies for sensitive bioreactor and purification trains. I will deliver a clean, well-documented HYSYS (.hsc) file with logically named streams and units, accompanied by a comprehensive sizing report for all equipment and streams, formatted for direct inclusion in your project documentation. The 2–3 page technical note will detail all assumptions, convergence approach, sensitivity analyses performed (e.g., yield, purity, utility variations), and justification for thermodynamic and unit operation selections. I prioritize rigorous simulation practice and clear documentation, and I can share anonymized sample HYSYS files and reports upon request to demonstrate my approach. I am available to begin this work immediately and commit to the accuracy and reliability your project requires.

Hi, I recently completed a similar Aspen HYSYS project simulating the conversion of biodiesel to pharmaceutical glycerol, dealing with specific biochemical purification quirks. I will apply this experience to build your model with a focus on thermodynamic accuracy, delivering a clean .hsc file and the detailed sizing reports you require.
