Question: Use a process simulator to model a two-stage compression system with an intercooler. The feed stream consists of (95 mathrm{~mol} %) hydrogen and (5 mathrm{~mol}

Use a process simulator to model a two-stage compression system with an intercooler. The feed stream consists of $95 \mathrm{~mol} \%$ hydrogen and $5 \mathrm{~mol} \%$ methane at $100^{\circ} \mathrm{F}$ and $30 \mathrm{psia} ; 440 \mathrm{lbmol} / \mathrm{hr}$ is compressed to $569 \mathrm{psia}$. The outlet temperature of the intercooler is $100^{\circ} \mathrm{F}$ and its pressure drop is 2 pisa. The centrifugal compressors have an isentropic efficiency of 0.9 and a mechanical efficiency of 0.98.

Determine the power requirements and heat removed for three intermediate pressures (outlet from the first three stages): 100, 130, 160 psia. If using ASPEN PLUS, use the MCOMPR module and the RK-SOAVE option.
