Issues related to the bottom ring pipe of the fractionation tower

The distillation column contains a stirred slurry ring coil and a stirred steam ring coil, both of which serve to prevent coking at the bottom of the column. What is the difference between the two?
Stirring the slurry in the loop can save steam and also reduce water separation during startup.
The agitating slurry loop in the distillation column is used to prevent the slurry from staying still for long periods, which could lead to coking and blockages in the tubes, while the agitating steam loop serves a stripping function.
Some devices use superheated steam; so what is the difference in performance between saturated steam and superheated steam?
Superheated steam is great – it doesn’t easily turn into water when the temperature drops. Its high temperature means that it remains in gaseous state even after releasing heat; otherwise, it would turn into water, and that wouldn’t be good
Steam and oil slurry serve the same purpose, with only slight differences in their auxiliary functions; for example, steam can be used to further strip the oil slurry, reducing the amount of diesel contained within it.
