Design of Pre-cooler (Brazed Aluminum Plate Fin Heat Exchanger)
The hot air comes into the precooler at temperature of 390°C and is expected to be
cooled to 8°C. the cooled fluid, that is, the coolant used in this design is cold
nitrogen at temperature of -195°C.
Assumptions;
* Heat loss by hot air equals heat gained by cold nitrogen.
Given that; øhin = 390°C, Øhout = 8°C, Øcin = -195°C
ṁ, = 131.4165 Kgmol

= 0.0365 Kgmol/s
3600s
Cpair = 1005J/KgK, CpN,= 1040J/KgK,
Density of nitrogen = 1251Kg/m³
Volume flow rate of N2 = 0.0000449m³/s
Recall that, mass flow rate (m) = density (p) x volume flow rate (v)
Hence, m. = 1251 × 0.0000449 = 0.0562Kg/s
%3D
Qn = m, × Cpair* (Øhin - Øhout)..
.3
Qu = 0.0365 × 1005 × (390-8) = 14012.715J/s
But Qh = Qc
Q. = 3668.25 = m, x CPN,× (Øcout - Øcin)
14012.715 = 0.0562 × 1040 x (Øcout" - 195)
3668.25
= 239.7467 = Øcout + 195
58.448
Øcout = 44.75°C
Øhin = 390°C
Øcout = 44.75°C
Øhout = 8°C :
