The present invention I) comprising: a first stage gas supplied to the separation module including the hollow fiber membrane by compressing the mixture containing the fluoride gas; II) separating from the first stage gas separation unit into a first enriched gas and the first permeate gas; And III) the step of separation into two enriched gas and the second permeate gas and supplied to the second stage gas separator comprising a hollow fiber membrane module of the first enriched gas; provides a fluoride gas recovery method comprising a.
According to the invention, the fluoride gas by using the selectivity is high the hollow fiber membrane or more of the steps 2, including modules multi-stage gas separation process of the nitrogen for the fluoride gas recovery fluoride gas from the mixed gas containing the fluoride gas at a high efficiency and feed It can be discharged separately up to 5% compared to the concentration, and can also increase the amount of gas discharged into the permeate gas by controlling the multi-stage gas separation portion stage cut increased.
