Patent ID: 6905663

Claim:
A method of abating fluorine from a fluorocompound-containing gas, said method comprising: heating the fluorocompound-containing gas to temperature in a range of from about 120° F. and about 300° F.; and introducing a catalyst and a fluorocompound abatement medium into the fluorocompound-containing gas to abate fluorine from the fluorocompound-containing gas, wherein the fluorocompound abatement medium comprises at least one medium selected from the group consisting of superheated steam, methane and hydrogen, with the provisos that when the fluorocompound abatement medium comprises superheated steam, the concentration of fluorine in the fluorocompound-containing gas is in a range of from about 1.1 vol. % to about 3.1 vol. %, based on the total volume of the fluorocompound-containing gas, and when the fluorocompound abatement medium comprises methane or hydrogen, fluorine is abated from the fluorocompound-containing gas under non-combustion conditions.
