DAV packed tower is built according to the counter-flow principle: the gas or airstream travels upwards through the tower, meeting the scrubber liquid - which flows downwards - on its way.Migration of unwanted components from gas phase to liquid phase happens in the packing, where a very intensive contact between both phases is organized. The performance of a packed tower scrubber can thus be improved by using the correct packing. In a well structured packing, the contact surface between unwanted gaseous components and the scrubber fluid is maximized. This enables optimal efficiencies, and thus low operational costs.
