As per the question, benzene is a distillate product.
00:09
Benzene is a, benzene is a distillate product.
00:24
So, then the value is x naught b equals to 99 .8 percent equals to 0 .990.
00:36
Then the bottom product composition is, bottom product composition, bottom product composition is, composition equals to x w b equals to 0 .5 percent equals to 0 .005.
01:04
Then assume the flow rate, assume, assume the flow rate, assume the flow rate is f equals to, f equals to 100 k mole per watt.
01:27
The heavy key components, we less volatile components as per tolerance, aminoxylene, ethylbenzene, paraxylene and the light key components are high volatile components like benzene and n -pentane.
01:43
So, the total, total balance is, total balance is f equals to d plus w.
01:59
So, the value of f equals to 100 d plus w.
02:04
This is equation first.
02:08
Then the f x f equals to, f x f equals to o x d plus w x w.
02:24
The values are f x f equals to 100 into 0 .7 equals to 0 .99 into 0 plus w into, into 0 .005.
02:41
This is equation second.
02:42
And then from equation one and equation two, we get from, from equation one and equation two.
02:58
We get, we get distillate, distillate equals to 70 .55 kilo mole per w.
03:14
So, reduce bottom product, we residue bottom product.
03:24
What is bottom product of residue is, bottom product equals to 29 .44 k mole by w.
03:39
Then given useful equations from the calculating minimum number and stages we have.
03:45
The minimum number is equals to i n x 0 i upon x 0 i into x b i upon x b i.
04:09
Then the values put in on this 1 .01 upon 0 .975 equals to 2 .62.
04:26
And the n minimum is, n minimum equals to n 0 .99 upon 1 minus 0 .99 into 1 minus 0 .005 by 0 .005 upon n 2 .62...
