Maka, konsentrasi black liquor = -81.48 (1.026)2 + 352.4 (1.026) - 269.2
= 6.514 % berat
Berat pikno + black liquor,out = 23.04 g
Berat black liquor = 10.34 g
Densitas black liquor = 1.030 g/cm3
Konsentrasi black liquor = 7.251 % berat
4. Perhitungan umpan
Contoh perhitungan :
Untuk variabel laju udara 0 m3/jam dan laju black liquor 100 l/jam
F = (Laju alir volumetrik x densitas black liquor)umpan
F = 82.7 l/jam x 1.026 kg/l
= 84.816 kg/jam
= 0.0236 kg/detik
5. Perhitungan produk
Contoh perhitungan :
Untuk variabel laju udara 0 m3/jam dan laju black liquor 100 l/jam
P = ( F x XF ) / XP

15. Heat capacity (Cp) gas masuk dan keluar
Dari tabel C.1 Smith, diketahui :
Cp/R = A + BT + CT2 + DT
-2
Dimana, untuk udara :
A = 3.355
B = 0.000575
C = 0
D = -0.00000016
TG,in = 30 °C = 303.15 K
TG,out = 111.0 °C = 384.15 K
R = 8.314 kJ/kmol.K = 0.082057 m3.atm/kmol.K
BM Udara = 29 kg/kmol
Cp,G,in = (3.355 + 5.75 x 10-4
(303.15 J) - 1.6 x 10-7
(303.15 K)-2
)
x 8.314 kJ/kmol.K / 29 kg/kmol
= 1.01182 kJ/kg.K
A-14
Cp,G,out = (3.355 + 5.75 x 10-4
(384.15 K) - 1.6 x 10-7
(384.15 K)-2
)
x 8.314 kJ/kmol.K / 29 kg/kmol
= 1.02517 kJ/kg.K
16. Harga densitas gas (ρG)
DP = 0 mmHg
P = (0/760) + 1 atm
= 1 atm
= (P/RT) x BM udara
= (1 atm / (0.08205 m3.atm/kmol.K x 384.15 K)) x 29 kg/kmol
= 0.9200 kg/m3
17. Harga G

Densitas gas (ρg)

18. Harga enthalpy gas masuk (HG,in) dan keluar (HG,out)
HG = Cp,G ( TG - Tref )
HG,in = 1.0118 kJ/kg.K x ( 30 - 0 ) K
= 30.3545 kJ/kg
HG,out = 1.02517 kJ/kg.K x ( 111 - 0 ) K
= 113.7938252 kJ/kg
19. Harga Q
F. hL, F + Q + G.HG,in = V HV + P hL, P + G HG,out
Maka,
Q = V.HV + P.hL,P + G (HG,out - HG,in) - F.hL,F
= 0.0085 kg/detik . 2658.524 kJ/kg + 0.015 kg/detik . 402.3 kJ/kg +
0 kg/detik (113.7938 - 30.3545) kJ/kg - 0.0236 kg/detik . 427.95 kJ/kg

20. Mencari Tw rata-rata
Harga Tw diperoleh dari dengan cara mengintegralkan menggunakan trapezoidal rule
T W = [z/2][T W1 + 2(T W2 + T W3 + T W4 + T W5 ) + T W6 ]/ [panjang absis]
dimana,
z = jarak antar termokopel
= 32 cm
TW = (32/2)(113.13 + 2(124.90 + 107.904 + 83.488 + 102.190)
+ 107.022)/(180 - 20 )
= 110.9086 °C
ΔTW = TW - TL
= 21.5 °C
21. Mencari koefisien perpindahan panas, hi
hi = Q / (ΔTW.π.D.L)
hi = 31.4727 / (17.6 x π x 0.028 x 2)
= 1.380 kW/m2.K
A-17
22. Mencari thermal conductivity black liquor (k bl )
kbl = 0.00144 Tbl - 0.335 S + 0.58
dimana :
kbl = konduktivitas black liquor ( W/m.K )
Tbl = suhu black liquor ( °C ) (20 °C - 100 °C)
S = fraksi massa black liquor ( 0% - 82% )
M. Johansson et al. / International Journal of Heat and Mass Transfer 52 (2009)
Untuk T = 89.4 °C, kbl = 0.00144 (89.4) - 0.335 (0.06514) +0.58
kbl = 0.687 W/m.K
23. Mencari NRe,L dan NPr,L
µL, rata-rata = (0.001061 + 0.001359) / 2
= 0.00109 kg/m.s
Cp = 3.722 kJ/kg.K
kbl = 0.000686913 kJ/s.m.K
NRe,L = 4[(F+P)/2]/(π.µ.D)
= 4[(0.0236 kg/s + 0.015 kg/s) / 2] / ( π x 0.00121 kg/m.s x 0.028 m )
= 937.068
A-18
NPr,L = Cp . µL, rata-rata / k
= (3.722 kJ/kg.K x 0.00121 kg/m.s) / 0.0006869 kJ/s.m.K
= 5.884

N = h . ΔTW / λair
λair,F = HV - hL,F
= (2658.524 - 347.4764) kJ/kg
= 2311.0476 kJ/kg
= 2311.048 kJ/kg x 19.1134 kg/kmol
= 44171.885 kJ/kmol
λair,p = HV - hL,p
= (2658.524 - 332.7647) kJ/kg
= 2325.7593 kJ/kg

= 44760.164 kJ/kmol
λair,rata-rata = 44466.025 kJ/kmol

Sehingga, flux massa (N) = 9.093 kW/m2.K x 17.6 K / 45879.67 kJ/kmol
= 0.0006676 kmol/m2.s
Koefisien perpindahan massa rata-rata ( β )
