A 50 mol% mixture of propane (1) and n-butane (2) enters an isothermal flash drum at 37°C. If the flash drum is maintained at 0.

Ulleksa [173]

Answer:

Explanation:

given data :

xi=0.5 (i.e. mole fraction 50%)

two liquid mixtures are given i.e. propane and n-butane

generally raoults law is applicable to ideal mixtures

the basic equation of raoults law

ki=pi saturated (T)/p...............1

first we take propane liquid

the basic forula to calculate psat is

%log psat=A-B/T(K)+C

for this we need to calculate tv=B-C/A-ln(P)

Substitute the values from antoine data

B=803.997,A=3.92828,C=26.11,P=0.6*10^-3

TV= 44.74K

NOW WE WILL take n-butane and calculate tv

for butane antoine data is as follows

B=2292,A=13.98,C=-27.86

Tv=134.96 k

now calculating psat

%log psat=A-B/T(K)+C

Psat for propane is -11.29 bar

psat for n-butane is -21.27 bar

pure component of vapour pressure is

1. p1=xi*psat=0.5*-11.29=-5.645 bar

2.p2=xi*psat=0.5*-21.27=-10.635 bar

2. now we are calculating the composition of phase

to calculate the composition

first we need to add up all the pure component pressure

p=p1+p2=-5.645+10.635=4.99 bar

i am assuming yi as vapour composition

yi=p1/p=-5.645/4.99=-1.131

y2=p2/p=-10.635/4.99=-2.131

so these are the minimum values of vapour pressure and pure component vapour pressure
