| description | The invention relates to a method for producing olefins, in which a hydrocarbon-containing charge material is introduced into a cracking furnace, where longer-chain hydrocarbons of the hydrocarbon-containing charge material are cleaved at least in part into shorter-chain olefins comprising ethylene and propylene. Cracked gas (1) formed in the cleavage is successively conducted through a lower section (11) and an upper section (12) of a wash column (10) in countercurrent to a liquid washing agent (43, 31). A petroleum-ether-rich fraction (43) in the lower section (11) of the wash column (10) and a water-rich fraction (31) in the upper section (11) of the wash column (10) are used as the washing agent (43, 31). The present invention likewise relates to a system designed to perform the method. |
