How Vane Inlet Devices work? Gas-Liquid Separators

Discover how Vane Inlet Devices (VIDs) improve the performance of gas-liquid separators and absorption towers. In this video, we explain the working principle of vane inlet devices and how they combine vapor distribution and liquid separation into a single, efficient system.

Watch as we break down the flow path inside the vessel, showing how high-velocity gas enters the inlet, changes direction through specially designed vanes, and separates entrained liquid droplets using centrifugal force. Learn how VIDs help prevent maldistribution, reduce pressure drop, increase tower capacity, and protect downstream internals.

🔹 How gas and liquid enter the separator
🔹 Flow through the vane channels
🔹 Centrifugal liquid separation mechanism
🔹 Vapor distribution across the tower cross-section
🔹 Benefits of vane inlet devices in absorber towers and gas-liquid separators
🔹 Improved efficiency, capacity, and reliability

Whether you’re an engineer, student, or process industry professional, this video provides a clear visualization of how vane inlet devices enhance separation performance in industrial vessels.
