PROCESS FOR CRACKING A HYDROCARBON FEEDSTOCK COMPRISING A HEAVY TAIL

摘要

The invention relates to a process for thermally cracking a hydrocarbon feed in an installation comprising a radiant section (6) and a convection section (7), wherein
a hydrocarbon feed stock is fed to a feed preheater 1 present in the convection section 7,
the heat pick-up of the feed preheater 1 is controlled by regulating the heat exchange capacity of an economiser 9, said economiser 9 being located in the convection section 7 between the feed preheater 1 and the radiant section 6, and wherein
the feed heated in the preheater 1 is thereafter cracked in the radiant section. The invention further relates to an installation for cracking a hydrocarbon feed.
