At high temperatures, coking is the main issue; at low temperatures, poor fluidity leads to condensation and scaling
I completely agree with you! The difference between coking and scaling!
What are the differences in the scaling behavior of catalytic slurry in the high-temperature and low-temperature areas? How to solve the structural problems of the slurry system? In catalytic slurry, coking occurs in the high-temperature areas as hard coke, while it forms soft coke in the low-temperature areas. Hard coke is formed when high-temperature oil slurry reacts exothermically with light hydrocarbons under the catalysis of metallic substances. Soft focus is a problem that arises from a lack of flow over an extended period during the operation of the slurry system. These are my personal opinions; if there are any mistakes, I earnestly ask for the leaders’ criticism and guidance. Thank you.
Ensure that the temperature of the slurry at the bottom of the fractionation tower remains below 350 degrees by using a slurry anti-scaling agent
