Diesel hydrocracking fractionator
Thread Content
Let’s discuss this: the temperature after air cooling at the top of the diesel hydrodesulfurization fractionation tower is closely related to the tower pressure. However, I’ve observed that sometimes when the pressure increases, the temperature also rises after air cooling; yet at other times, the temperature drops even though the pressure increases. What causes this?
The temperature after air cooling is highly dependent on the tower top temperature and the extraction rate
But its relationship with stress is sometimes proportional and sometimes inverse
