Your goal is to design a process to change a natural gas stream $($F $=1$ kmol$/$hr; $90\%$ CH$4,5\%$ C$2$H$8,3\%$ C$3$H$10,2\%$ CO$2)$ from $($T $=30$ C$,1$ bar$)$ to $(30$ C$,10$ bar$).$ Develop a feasible process superstructure and write the mathematical formulation describing the superstructure. State the Assumptions.
