Spray Towers

Spray Towers are used for low efficiency, low capital cost scrubbing of large particulates and highly soluble gaseous contaminants. Spray towers are especially effective for applications where the inlet contaminants hydrolyse to form difficult to handle solids, or where more efficient scrubbing is not desired for budget or technical reasons.

Operating Principle

A spray tower consists of an open chamber within the vessel which is irrigated with a spray of scrubbing liquor. The contaminated gas passes through the chamber, contacting the scrubbing liquor spray and the contaminants are washed from the gas stream.

ERG spray towers are provided as complete scrubbing packages, with the necessary fan, ductwork, pump, pipework and controls. In some applications, the spray tower may also be combined with other ERG mass/heat transfer equipment (venturi, tray tower, packed tower, V-tex® scrubber, etc).Refer to our other mass transfer technologies for full details of the range.
