Transcribed Image Text:3. A volumetric flow rate of 120 m³/min of mixture of real gases composed of
(40 mol % hydrogen, 35% CO, 20% carbon dioxide and 5% methane) is
cooled from 1000°C to 10°C isobarically at 35 atm. After cooling, the mixture
enters an absorber where the gases are contacted with liquid methanol at a
molar flow rate of 1.2 times that of the entered gas. All carbon dioxide and
98% of the methane is absorbed and none of the other gases entering in the
feed. The gas leaving the absorber is saturated with methanol at -12ºC is
then fed to a pipeline. (47.4 kmol/min, 0.0148 kmol/min). Hint: Hydrogen needs
