摘要：
An air separating unit which can jointly produce high purity nitrogen gas and compressed dry air of high quality freed of hydrocarbons such as methane and ethane. The air separating unit is constructed such that compressed dry air freed of hydrogen, carbon monoxide, carbon dioxide and moisture is cooled down near to its liquefying point and introduced into a rectification column (30) and nitrogen gas separated by rectification from the compressed dry air in this rectification column (30) is taken out as a product. The rectifying portion in the rectification column (30) is divided into a lower rectifying portion (34) and an upper rectifying portion (36), and in this lower rectifying portion (34), hydrocarbons such as methane are mainly removed from the compressed dry air, and the compressed dry air which has passed through the lower rectifying portion (34) is taken out as a product.
