Sieve Tray Scrubbers (VTS)

A highly effective contacting device for applications requiring a low liquid-to-gas ratio, Verantis^® sieve tray scrubbers are best suited for absorption of highly soluble but volatile compounds, such as alcohols, acetone, and some other organic compounds and acid gases.

Sieve tray towers achieve maximum contaminant removal with minimal water use and are less prone to fouling than packed towers. Verantis sieve tray scrubbers also remove particulate as small as 5 microns in diameter.

The systems consist of a number of perforated trays in a vertical cylindrical tower. Liquid flows horizontally across the trays while gas flows up through the tray perforations at high velocity, creating a frothing effect where gas absorption takes place. The liquid then flows through downcomer pipes to the lower trays. The number of trays can vary depending on the application and efficiency required.
