Awastewater stream is contaminated with 6 weight percent acetic acid and flows into a process at 10,000 kg/hr. prior to release, the level of acetic acid must be reduced to 0.5 weight percent. two solvents are being considered for extraction of the acetic acid: methyl acetate and 1-heptadecanol. the distribution coefficient kd (weight fraction aa in the solvent phase divided by the weight fraction aa in the water phase) for methyl acetate is 1.273. kd for 1-heptadecanol is 0.312. you can assume that both solvents are completely insoluble in water. a)how much of each solvent is required if the extraction is done in a single equilibrium stage? b)which solvent would you choose? provide reasons for your selection.'
