    This invention relates to a process for the purification of gases from acidic impurities by absorption by a liquid absorber.
    The purpose of the invention is to increase the degree of purification.
    Example 1. In the upper part of a steel extraction column with a height of 290 mm and a diameter of 63 mm, equipped with Rapsch rings under a pressure of 5.2 MPa and 8 l / h of a mixture consisting of 95 wt. n-butyraldehyde and 5 ma.ch, n-butyraldehyde. 5 m / h of synthesis gas containing 1 mg / m hydrogen cyanide, 0.8 mg / m hydrogen sulfide and 1.5 mg / m carbon dioxide as the main impurity are introduced in countercurrent. Thus, the absorbent is used in a concentration of 1.6 l / m of gas. In the gas leaving the upper part of the column, these impurities are no longer detected, i.e. the content of each component is less than 0.1 ppm. Gas loss and corrosion are not observed.
    Example 2. An example is taken with the difference that 10 m / h of synthesis gas containing 10 mg / m of hydrogen cyanide, 0.8 mg / m of hydrogen sulfide and 1.5 mg / m of carbon dioxide is subjected to countercurrent absorption of 5 l / h (0.5 l / m of gas) isononal under a pressure of 1.5 MPa and at 40 ° C. Cleaned

    these impurities are no longer detected in the gas. Gas loss and corrosion are not observed.
    Example 3 Example 1 is repeated, with the difference that 0.5 l of n-oil aldehyde per m of gas or 3 l of isosomaldehyde per m of gas or 4 l of a mixture of 95 parts by weight are used as absorbent. . n-butyric aldehyde and 5 wt.h. isomaldehyde per m of gas.
    In this case, in all cases, impurities are no longer detected in the purified gas. In addition, gas loss and corrosion are not observed.
    According to a known method, the degree of purification from acidic impurities is 10 ppm.
