Absorbed Statement / Hysys

                                                                                                              This lecture introduces the use of Aspen HYSYS

 to model continuous gas adsorption a process in a packed

 column The only unit process in the absorber is the tray section and

 the only streams are the upper steam and the lower liquid products .

                        

PROBLEM STATEMENT

CO2 is absorbed into propylene carbonate

in a packed column. The inlet gas stream

is 20 mol% CO2 and 80 mol% methane

The gas stream flows at a rate of 2 m³/s

and the column operates at 60°C and

60.1 atm. The inlet solvent flow is 2000

kmol/h. Determine the concentration of

CO₂ (mol%) in the exit gas stream, the

column height(m) and the column

diameter(m)
