Extracted text: PROBLEM 1 A 50:50 mixture of acetone (A) and water (W) is fed to a series of two extractors using methyl isobutyl ketone (M) as the extracting solvent. Each extractor was designed to output Si (kg) S2 (kg) the same amount of extract which was then mixed to obtain F (kg) 50% acetone 50% water R1 (kg) R2 (kg) EXTRACTOR 1 EXTRACTOR a combined extract having a composition of 46% acetone, 42% methyl isobutyl ketone, and 12% water. This mixture is then fed to a distillation column that is designed to obtain a final distillate composition of 97% acetone, 2% methyl isobutyl ketone, and 1% water. Overall, the process is designed to generate 25 kg of acetone-rich distillate (D) from 100 kg of the raw acetone-water mixture for every hour of E1 (kg) E2 (kg) D (kg). COLUMN operation. B (kg) If the two-extractor system is designed such that feeding 25 kg of methyl isobutyl ketone to the second extractor will generate a raffinate with a composition of 5% acetone, 2% methyl isobutyl ketone, and 93% water, and an extract with a composition of 26% acetone 69% methyl isobutyl ketone, and 5% water, determine the following: 1. The mass flowrate (kg/h) of the final raffinate stream. 2. The required mass flowrate (kg/h) of the methyl isobutyl ketone in the first extractor. 3. The composition (mass %) of the intermediate raffinate stream. 4. The percentage of the acetone lost in the bottoms.
