Title:
METHOD FOR PRODUCING NITROGEN-ENRICHED AIR BY USING EXHAUST FLUE GAS
Document Type and Number:
WIPO Patent Application WO/2020/218653
Kind Code:
A1
Abstract:
The present invention relates to a method for producing nitrogen-enriched air by using exhaust flue gas, the method comprising: (I) a step of supplying exhaust flue gas to an air compressor; (II) a pretreatment step of separating and drying moisture generated in the process of compressing the exhaust flue gas, and then removing the residual moisture and contaminants; and (III) a step of enriching nitrogen from the pretreated exhaust flue gas. Using exhaust flue gas, instead of external air, as the supply gas, nitrogen-enriched air can be produced at a higher flow rate with significantly increased efficiency even when a compressor having the same capacity as in the conventional method is used.
