Abstract

The present invention relates to a system for separating and recycling a perfluorinated or perfluor compound, and more particularly, to a system for separating and recycling a perfluorinated compound, which is developed to prevent damage of separation membranes and degradation of the separation efficiency of through the application of a constant pressure to respective separation membranes when the perfluoro compound passes through a plurality of separation membranes in a process of effectively separating, removing and recycling the perfluoro compound including sulfur hexafluoride primarily generated in a semiconductor manufacturing process.
