| Summary: | Nitroglycerin plant from Glycerol and mixed acid is designed to operate
continuously for 24 hours/day during 330 days/year. It has capacity of 20,000
tons/ year.
The reaction occurs in the isotherm process in flow stirred tank reactor
that operates at a pressure of 1 atm and temperature of 20oC. The reaction�s type
is exothermic. Regarding to the fact, the process need brine cooling liquid (CaCl2
25%) which flow through coil.
Plantation of 20,000 tons/year nitroglycerin is required 8.255,44 tons/year
of glycerol 98,5%, 27.374 tons/year of nitric acid 68%, 133,6 tons/year of
sulfuric acid 98%, 3.179,43 tons/year of Na2CO3 and 4.1667 tons/year of
ethanol. Utility components are 126.118,7 liters/year of water, 4.773,45
liters/year of fuel, 65.795 m3/year of CaCl2 brine, 270,8 kVA/year of electricity,
and 792.000 m3(STP condition) per year.
Planned factory will be established in Bekasi, West Java in the land area
of 20.000 m2 including area for expansion.
From the economic evaluation, we obtained the results: fixed capital of
Rp65.651.381.878,61 + US$3.678.794,05, working capital of Rp15.335.561.172,25 +
US$1.496.297,81. Return of Investment before Tax = 28,33% , Return of
Investment after Tax = 14,16% , Pay Out Time before Tax =2,61 years, Pay Out
Time after Tax = 4,14 years, Break Even Point = 40,57% , Shut Down Point =
13,3%, and Discounted Cash Flow Rate of Return = DCFRR = 18,67 %. From
the results of economic evaluation, we may conclude that the nitroglycerin plant
with capacity of 20.000 tons/ year is quite interesting for further study. |
