A method is described for treating a gas stream comprising fluorine (F2) gas. In a preferred embodiment, the method comprises adding water vapor to a gas stream and conveying the gas stream and water vapor to a reaction chamber containing a heated bed of material to react with F2 to form an inorganic fluoride while inhibiting formation of CF4 within the reaction chamber, and at least partially evacuating the reaction chamber so that the gas stream is conveyed to and from the reaction chamber at sub-atmospheric pressure. |
