Vapor Horn

Definition - What does Vapor Horn mean?

A vapor horn is a device used with liquid/vapor feeds to separate and introduce only the vapor into a process vessel for petroleum processing. The vapor horn works by using open bottom construction and induced deviating action. This is applied to designated liquid particles on the column wall, which then flows down into the collector tray.

Corrosionpedia explains Vapor Horn

Vapor horns are used for bulk phase separation of the vapor and liquid, and to provide initial distribution of the feed vapor. Some vapor horns are able to withstand high inlet velocities by providing pressure differentials.
