During the first start-up of atmospheric and vacuum distillation, can water pass through the heater when water-cooling is used?

During the first start-up of the atmospheric and vacuum distillation unit, can the water from the bottom of the initial distillation tower be directly transferred from the atmospheric furnace to the atmospheric distillation column? The company’s management says it’s not possible, but I think it is feasible – if we use combined water and air transport methods to thoroughly clean the furnace. What do you all think?
Yes, the water intertransport wants to go directly from the heating furnace to the atmospheric pressure tower
:Lol, without going through the heating furnace, how can water get to the atmospheric pressure tower? After the water is processed, oil processing follows, and at that point the water is removed
Hydraulic testing is the preparatory step for oil testing; in my opinion, it is possible to use it inside the furnace to check for leaks and to verify that the instruments are functioning properly
Add a temporary line that crosses the heating furnace; the concern is that the water supply may not be complete during transportation
There’s no major issue with feeding the tube; water comes out when hot oil is circulated
We do the same for water intermodal transport
What your supervisor meant is water flushing (the water flushing takes place before the water circulation; in fact, in order to achieve sufficient pressure, water flushing and water circulation occur almost simultaneously). As long as the pipes are cleaned thoroughly, they can be connected to the initial distillation tower. Normally, the pipeline is disconnected before the fuel line; after the pipes have been cleaned with water, the pipeline is reconnected, and then water is sent into the furnace tubes. At the end of the furnace tubes, there is a flange with an 8-shaped blind plate – that part is disconnected so that the blind plate remains in its closed position during flushing. Once the water is clean, the flange is reconnected to feed water into the initial distillation tower. I’m not sure if your supervisor conducts settlement tests on the towers; if such tests are carried out, the initial distillation tower must definitely be filled with water.
In water transportation, the focus is mainly on the instruments; then when should the instruments used in the furnace be inspected? Also, is it more serious for there to be oil leakage or water leakage?
