A stream of natural gas at pressure $2000$ kPa and $22$ C with composition as shown on table $1$ needs to be processed to remove C$2$ as part of a green process by using absorption process and diethanolamine $($DEAmine$).$ Complete the following task in HYSYS$.$

$($STEP BY STEP TUTORIAL$)$

For a feed of $100$ kgmol$/$hour of the natural gas at the inlet

conditions, present the phase envelope $($Bubble and Dew Point

curves$)$ of the mixture with identification of critical properties $($Pc$,$ Tc$),$

cricondentherm and cricondenbar.
