Ammonia from the exit of the reactor is completely separated from unconverted gases. To avoid the buildup of inerts, a small fraction (5%) of the unreacted gases purged and the balance recycled.

- Methanol (CH3OH) is produced in the reaction of carbon dioxide and hydrogen via the reaction and process given below: CO2+3H2→CH3OH+H2O The fresh feed to the process contains hydrogen, carbon dioxide, and 0.400 mol% inerts (I). The reactor effluent passes through a condenser that removes essentially all of the methanol and water formed and none of the reactants or inerts. The unreacted reactants and inerts are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. 100 mol/h of feed to the reactor (not the fresh feed to the process) contains 29.5 mol% CO2, 68.0 mol% H2, and 2.50 mol% inerts. The single-pass conversion of hydrogen is 46.71%. What is the recycle-to-fresh feed ratio?arrow_forwardA spent sulfuric acid solution is brought up to strength for a pickling process in a mixer. Spent solution at 3% sulfuric acid (by weight) is mixed with a 50% solution (by weight) to obtain the desired product concentration of 40% acid by weight. All are aqueous solutions. Determine all flowrates on the basis of 100 lbm/h of product. If the actual flow of the spent stream is 300 lbm/h, what must the flowrates of the streams be?arrow_forwardTo prepare a delicious banana milk on an industrial scale, there is an experimental process that consists of seven unit operations. A stream of banana (whose components are fruit, peel, and moisture) is fed to a peeler, where 99.9% of the peel is removed. This stream should become pulp, so it is mixed with an additive Q to avoid pulp oxidation. This mixture is then sent to an extruder press wherein a stream of a 50:50 mixture of additives Q and R is added. The resulting flow of 30 kg/h has a composition of 2% additive R and 5% additive Q. This flow is then fed to an agitated mixer. To the same mixer is fed a dairy stream of 250 kg/h that contains 70% milk (the rest is water) and a sweet aqueous stream that contains 30% sugar. For each 25 kg/h of dairy flow, 2 kg/h of the sweet flow is fed. The stream that leaves the agitated mixer has 5% fruit and 0.005% peel and enters a series of two thermal processes in which each operation allows 5% of the water and 2% of the milk to evaporate.

- A variation of the indicator-dilution method (see preceding problem) is used to measure total blood volume. A known amount of a tracer is injected into the bloodstream and disperses uniformly throughout the circulatory system. A blood sample is then withdrawn, the tracer concentration in the sample is measured, and the measured concentration [which equals (tracer injected)/(total blood volume) if no tracer is lost through blood vessel walls] is used to determine the total blood volume.In one such experiment, 0.60 cm3 of a solution containing 5.00 mg/L of a dye is injected into an artery of a grown man. About 10 minutes later, after the tracer has had time to distribute itself uniformly throughout the bloodstream, a blood sample is withdrawn and placed in the sample chamber of a spectrophotometer. A beam of light passes through the chamber, and the spectrophotometer measures the intensity of the transmitted beam and displays the value of the solution absorbance (a quantity that…arrow_forwardIt is intended to produce Propylene Glycol, PG (CH2(OH)CH(OH)CH3) by the hydrolysis of Propylene Oxide, PO (CH20CHCH3) in CSTR.
