🎥 Extractive Distillation in DWSIM Toluene-Isooctane Separation with Phenol Solvent
Struggling to separate azeotropic or close-boiling mixtures using simple distillation? This video dives into the powerful technique of extractive distillation—a game-changer for chemical engineers and process designers.
🔍 What You’ll Learn:
– Why simple distillation fails for certain mixtures
– How extractive distillation enhances separation using a selective solvent
– Step-by-step simulation setup in DWSIM
– Integration of solvent recovery for process efficiency
🧪 Case Study:
– Feed: Toluene + Isooctane at 25°C, 1 bar, 100 kg/hr (Toluene mole fraction: 0.45)
– Solvent: Phenol at 25°C, 1 bar, 25 kg/hr
– Extractive Distillation Column: 20 stages
– Solvent Recovery Column: 10 stages
💡 Phenol selectively interacts with toluene in the vapor phase, shifting relative volatilities and enabling clean separation. Watch how DWSIM models this process with realistic thermodynamics and flow parameters.
📊 Perfect for students, researchers, and professionals aiming to master advanced separation techniques and simulation workflows.
