Answer a question b) and c)

CHENG 111 - Introduction to Chemical Engineering 2021-22 Sem 2 Q1: In a particular installation, the purification system for the removal of sulfur compounds, designed to operate at a feed rate of up to 820 mol/h, is temporarily subjected to a feed rate of 1000 mol/h. Since the absorption system can only accommodate 82% of this flow, it is proposed that the overload be bypassed and that the exit H2S concentration from the absorption system be reduced frenough so that the mixed exit stream contains only 1% H2S and 0.3% COS (mole basis). The feed stream consists of 15% CO2, 5% H2S, and 1.41% COS, with the remainder being CH4, all in mole basis. a) Completely label the flow chart of the process. b) Do the degree of freedom analysis on all subsystems and on the overall process. c) Calculate all unknown mole fractions and molar flow rates in the system.
