After that, it is transported to lower column to rectify, where oxygenenriched liquid air from the bottom, liquid air from the lower part, and liquid nitrogen from condenser are gotten. All of them respectively enter subcoolers where they are subcooled by some nitrogen and waste nitrogen from upper column. Part of liquid nitrogen as the product is sent out of chilled box, and the other is delivered to upper column. After the separation of upper column, the liquid oxygen is taken out from the bottom, the waste nitrogen is taken out from the upper part of upper column, and nitrogen is taken out of the top of upper column.

进入下塔的空气经过精馏，得到富氧液空、液空、液氮。富氧液空、液空及部分液氮分别从下塔底部、下塔下部及冷凝蒸发器导出，进入过冷器，被从上塔来的氮气、污氮气冷却过冷，部分液氮作为产品送出冷箱，其余进入上塔。在上塔中，经过精馏分别在冷凝蒸发器底部、上塔上部、上塔顶部得到液氧、污氮气、氮气。
