High pressure at the bottom of the benzene removal tower
Thread Content
The bottom pressure of the benzene removal tower in our plant is high, around 45 KPa. The benzene gas condenser, oil-to-oil heat exchanger, and vent pipes have all been checked, and there are no issues with them. There is a slight issue with the tubular furnace: the temperature of the rich oil can only be raised to around 165, while the temperature of the superheated steam has already reached 490°C. Oil flow rate: 110 m³/h, steam flow rate: 1.4 t. Steam pressure: 0.5 MPa. I hope everyone can help analyze the reasons for the high pressure at the bottom of the tower. Moreover, the benzene content in the gas after washing the benzene tower is also as high as over 3 g. Thank you now
The tower top temperature is normal, and the quality of the crude benzene product is also satisfactory
What is the pressure at the top of the tower? . . The tower pressure difference is crucial. . .

Just looking at the feed rate, you have less steam
