DWSIM Valve Simulation | Joule Thomson Effect Explained | Propane Example

Hello everyone, welcome to Chemical Engineering Education

In this video, we simulate a Valve (throttling process) in DWSIM using Propane and analyze the Joule Thomson effect

👉 Inlet conditions
Temperature: 25 degree C
Pressure: 10 bar
Flow rate: 80 kg per hour
Phase: Liquid

👉 Property package used: Peng Robinson (ideal for hydrocarbons)

👉 Process details
Adiabatic valve
Pressure drop from 10 bar to 2 bar

📌 Key Concept
A valve is an isenthalpic process — enthalpy remains constant
This leads to temperature change due to the Joule Thomson effect

🎯 What you will learn
