Cooling tank issue
Thread Content
I would like to ask why the oil at the bottom of the coking contact cooling tower must be cooled using a cooling water tank – can’t other types of water coolers be used?
My personal opinion: The water tank has a simple structure; it does not require auxiliary facilities such as circulating water – it is sufficient to maintain a certain water level inside the tank. Moreover, given the variations in coking processes, this type of tank is used intermittently, and from the perspectives of investment and safety factors, it represents the most reasonable choice for a water tank.
Due to the high density and viscosity of heavy oil, a water tank is suitable as a cooler.
Are there many devices that use slurry to cool water tanks?
We use water tanks for both of our catalytic systems, before the slurry is discharged
The high water temperature in the water tank is suitable for cooling media with a high freezing point; moreover, the coil in the cold box is easy to clean
