Air equipped with a rectification column consisting of a high pressure column that separates raw air into liquid air and nitrogen gas, and a low pressure column that separates the liquid air into liquid oxygen and nitrogen gas. In the separation device, a nitrogen gas line is provided to take out low-purity nitrogen gas containing oxygen and carbon monoxide from the rectification column, and carbon monoxide and oxygen are reacted in the low-purity nitrogen gas to this nitrogen gas line. 1. An air separation device comprising: a reaction device that converts carbon dioxide into carbon dioxide; and an adsorption device that adsorbs and removes the carbon dioxide produced in the reaction device to produce high-purity nitrogen gas. 2. The air separation apparatus according to claim 1, wherein the nitrogen gas line takes out low-purity high-pressure nitrogen gas from the high-pressure column of the rectification column. 3. The air separation device according to claim 1 or 2, further comprising a sub-rectification column for obtaining high-purity liquid nitrogen from high-purity nitrogen gas discharged from the adsorption device, on the outlet side of the adsorption device in the nitrogen gas line. . 4. The high-pressure column of the rectification column is divided into an upper part and a lower part, so that the low-purity nitrogen gas in the lower part is introduced into the nitrogen gas line, and the high-purity nitrogen gas coming out of the adsorption device is returned to the upper part. The air separation device according to claim 1, characterized in that the air separation device is constructed as follows.
