Carbon monoxide is an important chemical raw materials which can be used for the synthesis of a variety of high value added products, such as acetic acid, acetic anhydride, formic acid, dimethyl formamide, light gas and metal carbonyl compounds, etc.

To get high purity carbon monoxide, cryogenic separation process could be used.  Cryogenic separation is to separate various components based on their different boiling points. According to the different contents in carbon monoxide, we use different combinations to realize separation and purification.
