Part A
the molecular weight of propane oxide is 12.011x3 + 1.008x6 + 15.999 = 58.079
the molecular weight of propane is = 12.011x3 + 1.008x6 = 42.08
the molecular weight of mCPBA is = 12.011x7 + 1.008x5 + 15.999x3 + 35.453 = 172.566
to produce 26 kg of propene oxide the amount of propane needed = (42.08/58.079)x(100/96)x26 kg= 19.6227 kg
the cost of propane needed is 19.612x10.97 $ = 215.261$
initial propane concentration is 21g/L
so the amount of CH2Cl2 needed is 19.6227/21x1000 L = 934.414 L
cost of CH2Cl2 needed is = 934.414 Lx2.12 $ = 1980.958 $
the amount of mCPBA needed is (172.566/58.079) x (100/96) x 26 kg= 80.471 kg
cost of mCPBA needed is = 80.471 x5.28 $ = 424.885 $
total cost for waste disposal is $5x26 = $130
total cost for production = $(215.261 + 1980.958 + 424.885 + 130) = $2751.1047 for 26 kg
total earning from 26 kg of propane oxide = 258.25 x 26 = $6714.5
total profit = $6714.5 - $2751.1047 = $3963.395
Part B
since the yield is 89% to produce 26 kg of propene oxide the amount of propane needed = (42.08/58.079)x(100/89)x26 kg= 21.166 kg
the cost of propane needed is 21.166 x10.97 = $232.191
since 25% of catalyst loaded is being used and remaining is being recovered the neat amount of catalyst required is = 21.166x25/100 = 5.2915 kg
the cost of vanadium catalyst needed is 5.2915 x57.50 = $304.261
the molecular weight of hydrogen peroxide is 34.0147 g/mol
the amount of hydrogen peroxide needed is (34.0147/58.079) x (100/89) x 26 kg = 17.109 kg
the cost of hydrogen peroxide needed is 17.109 x 1.96 = $33.534
the amount of supercritical water needed is = 21.166x32 = 677.312 kg (32 kg water for 1 kg propane)
the cost of supercritical water needed is = 677.312x1.85 = $1253.027
total costing for 26 kg of propane oxide = 232.191+304.261+33.534+1253.027 = $1823.0132
total profit for 26 kg = 6714.5-1823.0132 = $4891.487
