How to define a Pseudo-Component in Aspen Plus | Biodiesel Fatty Acid Fraction Tutorial

In this Aspen Plus tutorial, learn how to model an unknown fatty acid fraction as a pseudocomponent in a biodiesel process simulation — using only its normal boiling point (300°C) and liquid density (870 kg/m³).
✅ What you'll learn:
• How to define a pseudo-component in Aspen Plus Component Selection
• How to enter limited physical properties (NBP + density) using the pseudocomponent property editor
• How to select an appropriate thermodynamic method (Ideal method for demonstration)
• How to review and display calculated unknown parameters using the Review tool
⚙️ Software used: Aspen Plus

📌 This tutorial is perfect for:
→ Chemical engineering students working on process simulation assignments
→ Engineers modeling biodiesel, oleochemical, or refinery processes in Aspen Plus
→ Anyone dealing with ill-defined heavy fractions or petroleum pseudocomponents

💡 Even with minimal data, Aspen Plus can estimate a full set of thermodynamic parameters — this video shows you exactly how.
