Question: 3. A feed stream containing CO2 and H2S is fed to a mixer, where it is mixed with a fresh feed stream containing 100% solvent

3. A feed stream containing CO2 and H2S is fed to a mixer, where it is mixed with a fresh feed stream containing 100% solvent (S), and a recycle stream. The mixer effluent is fed to a flash unit, for the purpose of separating the CO2 from the H2S. The liquid stream leaving the bottom of the flash is fed to a valve, where it is split equally into two streams, so that 1/2 of the stream is recycled back to the mixer, and the other 1/2 is removed from the system. - The vapor stream leaving the top of the flash contains 67%CO2, and remainder H2S and S. This stream contains 25% of the CO2 from the fresh feed and 15% of the H2S from the fresh feed. - The liquid stream leaving the bottom of the flash contains 5%CO2, and remainder H2S and S. There is no chemical reaction. Process is continuous and at steady state. a) Completely label each stream on the process flowchart, assigning variable names. Use the conventions described in class ( ni for molar flow rates, yi for mole fractions). b) Do a degree of freedom analysis each of the 4 systems: Label each equation with the SYSTEM AND SPECIES being balanced; or name of type of information (if not a material balance)
