Part 1: Design Spec In a given process, it is desired to extract lsopropanol from a mixture of water and lsopropanol of 75 mol% and 25 mol% respectively. Pentanol is used as a solvent with an initial mass flow rate of 100 kmoI/h. The desired mole fraction of Iso-propanol in PROD-2 stream is 16 i0.002 mo|%. In order to determine the required mass flow rate of pentanol to perform the extraction, a design spec is implemented on Aspen. Answer the following questions: Q1) Where can you find the design spec on Aspen? (5 points) C12) Explain how the design spec differs from the sensitivity analysis in Aspen. (10 points)
