Plants need phosphate. Phosphate rock [ (CaF)Ca4(PO4)3] is used extensively by organic farmers, but releases phosphate very slowly. If phosphate rock reacts with sulfuric acid (H2SO4), monocalcium phosphate [CaH4(PO4)2H2O] calcium sulfate (CaSO4) and hydrogen fluoride (HF) are produced. Rapid release superphosphate fertilizer is the mix of monocalcium phosphate and calcium sulfate produced in this reaction. (HF) is not used. You are in charged of designing a process to produce 600 tons of superphosphate fertilizer per day. Calculate the tons/day of phosphate rock and sulfuric acid rquired. If phosphate rock sells for $125/ton, sulfuric acid for $60/ton and superphosphate for $280/ton, what annual profit can you expect? Assume the process operates 350 days per year
