The bromine index of the benzene product from the extraction unit is too high
Thread Content
Analysis of the benzene product obtained through the side line showed that the bromine index was originally zero, but it has suddenly risen to over 100, around 120. What should I do? The clay tower is in operation; the temperature upon entry into the tower is 157°C, and it is 150°C upon exit. The pressure in the clay tower is 2.1 MPA
Increase the operating temperature of the white clay tower, while paying attention to the reflux ratio of the recovery tower to ensure that cyclosulfone is not carried in the mixed aromatics.
The white clay has lost its effectiveness; it’s time to replace it
I keep it around 0.6-0.7
How much does the design institute usually provide for process card design?
All of this is specified in the design documents provided by the design institute, but it is also necessary to determine the appropriate reflux ratio based on the conditions of one’s own installation
