Description

ASSIGNMENT FOR A COURSE PROJECT

Calculate a shell-and-tube heat exchanger for cooling 500m3/h (under normal conditions) of natural gas from t1n. = 44°C to t1k =12°C.

Composition of natural gas (under normal conditions):

ComponentVolume, m3Volumetric composition, %
Methane (CH4)471,994,38
Ethane (C2H6)204,0
Bhutan (C4H10)5,51,1
Propane (C3H8)2,60,52
Total:500,0100,0

Natural gas pressure rabs = 24 atm. The refrigerant is the same gas under the same pressure, but with a temperature varying from -35 to +19°C.
