Simulation of the benzene removal tower
Thread Content
I am currently working on a simulation calculation related to a benzene removal tower, using PROII, and I don’t know where to start. I would be extremely grateful if experienced friends could offer some guidance! Oil-rich feed: 240 M3 at 180 degrees; it is required that light benzene be produced at the top of the tower, while heavy benzene and naphthalene are obtained from the side streams
With the feed conditions and discharge requirements established, what’s left that can’t be addressed? Just build a distillation tower for simulation, right?
But there’s no specific process for feeding the rich oil, right? Also, I’m not sure how to choose thermodynamics Is it NRTL or SRK? Could anyone who has succeeded in simulating this please offer some help?
How do you determine the composition of the rich oil?
I think the boiling range of the oil-rich mixture is determined by taking the boiling range of the washed oil and adding 5% naphthalene, 2–2.5% benzene, and 1% water to it as the feed material – is that correct?
Could anyone with experience give some advice?
Bro, you have all the parameters; just check the design specifications and do the calculations!

(In the case of a complex column with two or more key components, SHORTCUT can be used to determine the minimum number of theoretical plates and reflux ratio required for each component separately, and these values can then be combined to calculate those parameters for the complex column.) Add controllers and use REDFRAC to compute the number of theoretical plates.
