Abstract
In a process for producing olefins, a hydrocarbon-containing feed is fed into a cracking furnace where relatively long-chain hydrocarbons of the hydrocarbon-containing feed are cracked at least partly to form shorter-chain olefins, encompassing ethylene and propylene. Cracking gas () formed during cracking is conveyed in succession through an upper section () and a lower section () of a scrubbing column () in countercurrent to a liquid scrubbing medium (), is proposed. A fraction () rich in petroleum spirit is used in the lower section () of the scrubbing column () and a water-rich fraction () is used in the upper section () of the scrubbing column () as scrubbing medium (). A plant configured for carrying out the process is likewise provided by the present invention.
