Recycle Block Simulations| Complete Flowsheet| Complex Distillation | DWSIM Simulation for Beginners

In this tutorial, we take our DWSIM simulation to the next level by integrating a Recycle Block to create a fully continuous flowsheet. After completing the setup for an Extractive Distillation Column and a Solvent Recovery Column, we demonstrate how to loop the recovered solvent stream back into the process—just like in real industrial operations.
🧪 What You’ll Learn:
– How to simulate extractive distillation for separating close-boiling components
– Configuring a solvent recovery column to purify and reuse the solvent
– Setting up a recycle block in DWSIM to connect unit outputs and close the loop
– Tips for achieving convergence and stable simulation results
🔁 This video is perfect for chemical engineering students, simulation enthusiasts, and professionals looking to model sustainable and efficient separation processes.
