Abstract (en)

A gaseous fluid (6) is treated by bubbling in a treatment composition (26) containing magnesium chloride, sugars and surface-active agents in an aqueous solution. The composition (26) is held in a vessel (11) within which the gaseous fluid is also submitted to a dehumidification step by filtering through an expanded-clay bed (41), preceded by an active-carbon filter bed. The fluid thus treated is brought into contact with atomized paint or other electrostatically charged element, to neutralize the effects of the electrostatic charge. <IMAGE>
