Summary:recovery of gaseous wastes. SUBSTANCE: process waste gases containing krypton and xenon are passed in advance through gas-lift apparatus. Suitable absorbent is supplied to mentioned apparatus and temperature lower than boiling point of component being extracted, that boils at high temperature but not higher than air and other component, is maintained. This process is followed by ultrasonic treatment stage from air and other component, temperature being maintained above boiling point of other component and air but below that of component being extracted. Then absorbent enriched by component being extracted is conveyed for other ultrasonic treatment carried out at temperature higher than boiling point of absorbent. Component being extracted is extracted in gas phase and absorbent is returned to cycle. EFFECT: improved purity of end products upon extraction in continuous process. 1 dwg
