What is the impact of preheating the coking tower in delayed coking on the entire plant, and how is the best way to carry out this preheating?
During preheating, it has a significant impact on distillation. During oil rejection, it should first be sent to the vent tower; once the temperature rises, the distillation process is adjusted. It is essential to control the temperature carefully here – high temperatures have little impact on distillation, but they increase the load on the vent tower and thus raise indirect energy consumption ； Slightly lower, with increased distillation effects. This can be adjusted appropriately according to one’s own device
Ours changes to fractional distillation at 200 degrees: L:L:L:o:o:o:o. . . . . . . . . . .
The impact is significant; especially when the load is low, it can cause serious systemic effects. The current method of preheating coke valves without blockages involves using the heat within the system to preheat the coke tower; if heat from outside the system is used for this purpose, the problems associated with the system can be significantly improved!
