Sorry for late replies. To everyone getting negative values for Rmin, please check that your theta should be between the relative volatilities. Make sure you have a reasonable initial guess.
Please explain how to select numbers of theoretical plates in crude oil distillation column/tower on the basis of crude oil properties (during designing of CDU).
What to do if the two columns are thermally coupled, how to apply underwood's equation for that system. How to apply underwood equation for petlyuk config..
If I have the coefficent ratio (c), can I calculate the Rmin without Underwood equation? For me, the c is 1.35 Using this equation : copt=1+0.192*(Rmin/Nmin)^0.5

there are two theta which value we should take

Thanks for the clear explanation! Worked perfectly for me!
How can I do the question if maybe the values of theta are more than 1

this is great thank you so much
What value should I take for the initial guess of theta?
Hey, your videos are really good
Thank you!
Why did i get negative Rmin? 😭
