Caffeine is often added to headache medications because it affects the flow of blood in vessels and may enhance the pain-relieving qualities of the medication. A scientist has been tasked with evaluating one process that extracts caffeine from a coffee slurry, and he decides to study a small-scale version of the process. A coffee slurry containing a mass fraction of 0.01 g of caffeine per gram, 0.08 g of other solids per gram, and 0.91 g of water per gram is fed to a mixer at a rate of 390.0 g/min. Na, co, is added to the mixer such that the mass ratio of Na, Co, to coffee slurry is 0.0400. This aqueous solution proceeds to an extractor where CH, Cl, is added such that the mass ratio of CH, Cl, to coffee slurry entering the extractor is 0.350. Two streams leave the extractor. The first is a mostly aqueous stream that leaves the process containing some caffeine, all of the other solids in the original slurry, all of the Na, Cox, all of the water, and 2% of the mass of CH, Cl, entering the extractor. The second stream contains the remaining caffeine and CH, Cly, and it enters an evaporator that completely vaporizes the CH,CI. The vaporized CH, Cl, is condensed and is merged with the fresh CH, Cl, on the way to the extractor. The dried caffeine crystals exit the evaporator and leave the process. Of the caffeine entering the process, a fraction of 0.960 leaves the process in this product stream. Label the process flow diagram. Label any quantities as "unknown" if a calculation is needed to obtain the numeric value. Do not leave any answer space blank. g NaC0/min CH.CL/min CHCI./min SCH.Cl/min m coffee slurry/min caffeine/min Mixer Extractor Evaporator caffeine/g X, gother solids g water m- = g mostly aqueous solution/min g caffeines gother solids/g Na,C0/8 g waterig 2CH.CH = Answer Bank 0.02 unknown 0.91 0.0400 0.960 390.0 0.08 0.01 0.350 What is m, the mass flow rate of crystallized caffeine? m7 = g caffeine/min What is m4, the mass flow rate of fresh CH, Cl, to the process? m = g CH,C1,/min What is the ratio of the flow rates of recycled CH, Cl, to fresh CH, Cl,? ratio
