Abstract |
The company performs continuous absorption of fluorine - containing waste gas. This low-waste technology is a continuous method for absorption of SiF4 from waste gas of the phosphate-fertilizer industry. It works upon the principle of turbogrid absorption. In an absorption tower, the waste gas is cleaned of fluorine streams through several, specifically-designed turbogrid trays, one after the other. These turbogrid trays are sprayed with aqueous hexafluorosilicic acid. In the turbogrid trays, stable of dynamic bubbling layers develop which offer a big mass-transfer surface for the absorption. |
