[54] PROCESS FOR CONVERTING HYDROCARBON INPUTS TO OLEFIN-CONTAINING PRODUCT STREAMS BY THERMAL STEAMCRACKING
[57] Abstract: The invention relates to a process for converting inputs composed of hydrocarbons by thermal steamcracking to at least one olefin-containing product stream comprising at least ethylene and propylene, with at least partial conversion of the inputs in at least one first cracking furnace (1) and in at least one second cracking furnace (2). According to the invention, a fresh input (B) is fractionated into at least one first and one second fresh input fraction (B1, B2), and the first fresh input fraction (B1) is conducted at least partly into the first cracking furnace (1) and the second fresh input fraction (B2) at least partly into the second cracking furnace (2).
