| 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. |
