| 摘要 |
The invention relates to a method for converting hydrocarbon feedstocks by means of thermal steam cracking into at least one olefinic product flow containing at least ethylene and propylene, said feedstocks being at least partially converted in at least a first cracking furnace (1) and in at least a second furnace (2). According to the invention, a fresh feedstock (B) is fractioned in at least a first and a second fresh feedstock fraction (B1, B2), and the first fresh feedstock fraction (B1) is fed at least partially into the first cracking furnace (1) and the second fresh feedstock fraction (B2) is fed at least partially into the second cracking furnace (2). |
