Tray Scrubbers

Tray Scrubbers (also known as sieve tray scrubbers) are a highly effective contacting device for applications requiring a low gas-to-liquid ratio.  The design consists of a number of perforated trays in a vertical cylindrical tower.  Liquid flows horizontally across the trays while gas flows up through the perforated tray at high velocity creating a frothing effect where the 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.

Sieve trays are best suited for absorption of highly soluble but volatile compounds such as alcohols and other soluble organics as well as some acid gases. This type of configuration minimizes water usage while achieving maximum contaminant removal. Sieve trays are also less prone to plugging than packed towers and can effectively remove particulate down to 5 microns in size.
