After the feed oil of the catalytic cracking unit is filled with water, what are the possible places where gas blockage may occur?

Let’s talk about the parts where air blockage is likely to occur after the feed oil of your catalytic unit is filled with water. Thank you all.
It is possible to change to a position above 100, depending on your heat exchange process. . . If the raw material starts to be delivered from the tank area 70, it is estimated that it will start to vaporize and cause vapor lock when entering the second stage of the heat exchange process. . . :loveliness:
Parts that may cause air blockage include:: Raw material heat exchangers, especially oil slurry heat exchangers, heating furnaces, etc.

It will appear in the heat exchange process where the temperature is above 100℃
I also agree that the reflow heat transfer from the top of the first stage will produce
Temperature is a relationship, and the pressure inside the pipeline must also be taken into consideration. Therefore, vapor lock may only occur in the pipeline of a general installation at about 120°.
From the pressure gauges at various places in the on-site process, I can see that the main air resistance of our device may be at the nozzle where the raw oil enters the riser.
