What will happen if the top temperature of the benzene removal tower remains at 98 degrees?
Why 98 degrees? Being in this position for a long time evaporates the light components in the washing oil, increasing the consumption of washing oil.
98 degrees is quite high; usually it’s around 90–95
The crude benzene spotting fails to meet standards, and a large amount of washing oil is consumed. It generally needs to be kept around 90°C.
The temperature is too high; it should generally not exceed 93, otherwise the oil consumption will be unmanageable for you.
In fact, it’s not necessarily necessary to keep the temperature at a specific level; this depends on the manufacturing processes used in your plant. If the quality of crude benzene is well above 91%, it’s necessary to increase the temperature at the top of the tower until it approaches 91%. In our facility, this temperature is usually around 98 to 99 degrees, resulting in an distillation yield of 91.5%. However, when conducting comparisons, some companies maintain a temperature of only 95 degrees at the top of their towers
1. The volume of benzene vapor at the top of the benzene removal tower increases； 2. Increase in crude benzene production ； 3. Decline in the quality of crude benzene ； 4. Increased oil consumption for washing ； 5. Increase in the pressure of the benzene removal tower ； 6. Increased water demand for the cooler ；
:D has been learned: higher temperatures lead to higher yields but lower quality
