The role of flushing oil in catalytic devices
Thread Content
What is the function of the flushing oil in the catalytic device? Also, what is the purpose of introducing diesel into the bottom of the burned tank? Please discuss this, thank you
Functions of flushing oil: 1. Isolation 2. Cooling 3. Flushing 4. Lubrication
Function of flushing oil: flushing, displacement, cooling. Diesel is introduced into the bottom of the coking tank: this raises the temperature of the two vessels
The flushing oil is for instruments! Burnt tank diesel is used as a combustion fuel to heat the catalyst when the bed temperature is low!
Coked tank diesel is used as a burning fuel to heat the catalyst in the coked tank when the bed temperature is low or at startup! :loveliness:
It doesn’t seem quite correct to say that diesel is poured into the bottom of the burned-out tank; rather, diesel should be sprayed there. The purpose is to raise the temperature of the regenerator, so that the dense phase reaches a certain temperature. However, spraying can only take place once the temperature reaches the ignition point of diesel (370 degrees), and spraying must be stopped when steam is introduced into the regenerator
Rinsing, replacement, diesel is required to provide the heat needed to raise the catalyst temperature
Is diesel injected into the bottom of the burned-out tank? Does this refer to the injection of burning oil into the regenerator at the beginning of operation in order to raise the bed temperature? Such injection is possible only if the temperature of the regenerator bed exceeds the auto-ignition point of diesel, and there must be a sufficient amount of material in the regenerator to cover the diesel nozzle; otherwise, problems will occur. Additionally, during normal operation, spraying may also occur if the regenerator bed temperature is too low.
1. As a flushing oil for instruments. 2. As a burning oil for the regenerator; it is introduced at the bottom of the coking tank for this purpose, to aid in heating during the startup process. But we never use it.
It has the functions mentioned above; burning oil is used to raise the bed temperature, but this is generally not necessary
The flushing oil mentioned on the 1st floor is referred to as flushing oil in the field of instrumentation; it is used to clean the pressure leads of instruments, and diesel is commonly used as its component. When used in pumps, it is called sealing oil, and its function is as described on the 3rd floor. It is not accurate to say that diesel is injected into the bottom of the coking tank; after additives are added and the bed temperature reaches 370 degrees, diesel is sprayed in to raise the temperature – this should be referred to as injecting combustion oil into the bottom of the coking tank.
