How Chimney Collector Trays Work

Discover how a Chimney Collector Tray works inside an Absorber Tower and why it plays a critical role in efficient gas-liquid separation. In this video, we explain the design, function, and operating principle of a chimney tray, including how it collects liquid, allows vapor to pass through the chimneys, and ensures proper liquid redistribution to the sections below.
