I would like to ask the experts what is an appropriate storage temperature for the residue tank area

Why keep it so high? Are there any special requirements? What is the design temperature of the storage tank, and can it withstand such high temperatures? What is the initial boiling point of residue? At such high temperatures, could the volatile light components evaporate, leading to excessive VOC emissions from the tank top as well as an unpleasant odor? Furthermore, maintaining such a high temperature requires much stricter insulation for the storage tank; otherwise, heat loss would represent a significant waste as well. Generally, the temperature at which the residue from atmospheric and vacuum distillation units is sent out is controlled around 120 degrees; a range of 100 to 130 degrees is sufficient to meet the requirements regarding the fluidity of the residue, while also ensuring environmental protection and safety during storage and transportation. When the control temperature is below 100 degrees, ensure that the residue oil is free of water.
It’s mainly that the value from the tank area to the plant side is 160, which is why I wanted to ask
Is the temperature sent from the tank area to the unit 160? What device?
The fact that such high temperatures emerge from the device indicates that the waste heat from the material is not being utilized effectively; generally, the temperature needs to be reduced to 60–70°C for it to be considered safe.
In our residue hydrogenation unit, the operating temperature of the residue fed into the reactor is also 150°.
