Title:
How to manufacture Olefin by heat vapor decomposition in a cracking furnace
Document Type and Number:
Japanese Patent JP6181181
Kind Code:
B2
Abstract:
The invention relates to a process for converting hydrocarbon feeds by thermal steamcracking to at least one olefin-containing product stream comprising at least ethylene and propylene, with at least partial conversion of a first hydrocarbon feed in at least one first cracking furnace (1) and of a second hydrocarbon feed in at least one second cracking furnace (2). According to the invention, the second hydrocarbon feed is converted in the second cracking furnace (2) with cracking conditions that lead to a ratio of propylene to ethylene of 0.7 to 1.6 kg/kg, and the first hydrocarbon feed is converted in the first cracking furnace (1) with cracking conditions that lead to a ratio of propylene to ethylene of 0.25 to 0.85 kg/kg at the cracking furnace exit, the value for the ratio of propylene to ethylene for the second hydrocarbon feed being above the value for the ratio of propylene to ethylene for the first hydrocarbon feed.
