ABSTRACT:
An improved scrubber tower is provided for removing pollutants from hot, corrosive off-gases from chemical processes, such as processes for the production of titanium dioxide pigments. The tower is formed from wood strip baffles treated with fire resistant chemicals arranged in alternate layers extending perpendicularly to each other and secured with titanium fasteners and enclosed in fiber glass walls, the flow passages through the tower being of large cross sectional area relative to the cubic feet of off-gas scrubbed per unit of time as to maintain a relatively low off-gas velocity upwardly through the tower, substantially the same as the velocity that would be present under natural draft conditions, and at low pressures, only slightly above ambient air pressure.
