Mixing process for sulfuric acid production.
1) You need to prepare an aqueous sulfuric acid solution that is 35.0 wt% H2SO4 (specific gravity is 1.274). What is the molarity of the solution?
2) The solution will be prepared by mixing two streams of H2SO4, one more concentrated (60.0 wt%, SG=1.498) and one more dilute (20.0 wt%, SG=1.129). Draw and label a flow chart for this process, labeling both masses and volumes. Assume a basis of 100 kg of the 60% solution, then calculate the feed ratio in terms of liters of 20% solution per liter of 60% solution.
3) What feed rate (in L/h) of the 20% solution would be required to produce 1000 kg/h of the 35.0 wt% product?
