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

$$Based on the phase envelope graph and the conditions of the natural

gas stream, indicate the state of the mix $($gas$,$ liquid solid$)$ and which

unit process are required to increase the percentage of light

hydrocarbon components. Support your answer with the phase

envelope and case study.

$6.$ Investigate and propose a process flow diagram PDF $($only using

Visio or PowerPoint$)$ for CO$2$ absorption to clean natural gas, explain

the purpose of each required process unit and main variables

affecting the process.
