PENYELESAIAN :

Misalnya :

T = 423 K

Dengan menggunkan rumus antoin

Dit : P & T ?

Jawab :

Mencari P masing-masing Komponen

P(etilen) : ln P = A(-B/t+C)

Ln P= 13.8182(-1427.22/423+(-14.3080)

Ln P= 10.326 kPa

P(Air) : Ln P= 16.5362(-3985.44/423+(-38.9974)

Ln P=6.1575 Kpa

Mencari P (total)

P(total) = P(etilen) * X(etilen) + P(Air) * X(air)

= 10.326 * 0.5 + 6.1575 * 6.1575

= 6.1575

F=1000 mol/menit

V=etilen 99%

L = Air 99%

Etilen = 50% Air = 50%

Mencari K masing-masing komponen :

K(etilen) : = P(etilen)/P(total)

= 10.326/6.1575

= 1.675

K(air) : = P(air)/P(total)

= 6.1575/6.1575

= 1

Mencari V :X1 = Z1/(1+V(K1-1))0.01 = 0.5/(1+V(1.676-1))

0.01+(6.76*10^-3V)=0.5

(6.76*10^-3)=0.5-0,01

V=0.49/(6.76*10^-3)

V = 72.485

Mencari Neraca massa total

F = L + V

100 = L + 72.485

L = 100 - 72.485

L = 27.615 Mol/Menit
