Question

Problem 3 A flash drum is separating a feed consisting ofnp wt % n-propanol and ip wt % isopropanol with F kgmoles/hr at Tdrum °C and Pdrom kPa. Use the Rachford-Rice equation to find V/F, V, L, and then and y. Note: This does not have to be trial-and-error. Determine K values from Raoult's law using Antoine equation for vapor pressure. Watch your units. The Antoine constants are n-propanol: A-7.84767, B-1499.2, C-204.64 isopropanol: A-8.11778, B-1580.9, C-219.61 Where the form of the Antoine equation is Logio(Vp)-A-BI(T+c) VP in mm Hg and T in C Source: J.A.

Explanation / Answer

I will give brief explanation to solve this problem first of all using the antonie equations you are able able to find vapor preassure right?(having doubt comment me)--------(1)

next we have feed values F,so use the two formulas given below

F=L+V and F*Xf=L*X+V*Y

we have X and Y values also so now you are capable of finding L,V values for six given feed compositions understand?(not?,comment me)------------------(2)

Finally we need to calculate the values of K from raoults law and is given as (total preasure)*(mole fraction in vapor phase)=vapor preasure *K

Now you have all the stuff to calculate K values for 6 feed compositions(yes/no comment me)---------------(3)

hope you will solve this and upvote to my answer.
