| description | Polyvinyl alcohol is widely used as raw material on adhesives, protective
colloids, and paper industry. The use of polvinyl alcohol as chemicals is also
found in textile, pesticidse, cosmetics, and fertilizer industry. The preliminary
design of polyvinyl alcohol plant is aimed to study the technical and economical
feasibility of the plant upon establishment. Polyvinyl alcohol plant is designed at
30.000 ton/year capacity and to be operated continuously on 330 days/year. Vinyl
acetate of 8,594.84 kg/hour and methanol of 3,008.19 kg/hour is used as raw
materials, with 86,23% conversion of polimerization reaction. Methyl acetate is
obtained as side product by 6,382.17 kg/hour.
Polyvinyl alcohol is produced through two steps. The first phase is vinyl
acetate polymerization by using solution polymerization method with methanol as
the solvent. Polimarization is conducted on a continuous stirred tank reactor with
azobisisobutyronitrile as the initiator on 3 atmosphere and 80
0
C. The second
phase is hydrolisis of polivinyl acetate by methanol using NaOH catalyst.
Hydrolysis reaction is conducted on two continuous stirred tank reactors
arranged in series on atmospheric pressure and 55
0
C.
The plant is designed to be constructed in Bontang, East Borneo on a
46,000 m
2
area and employs 235 labors. Energy consumption is sought to be
3,543,645.60 kWh/year of electricity and 5,786.83 m
3
/year of diesel. The utility
unit is designed to provide 5,233.75 kg/hour of water and 150 m
3
/hour of
instrumental air.
Total capital investment costs $ 50,965,527 and Manufacturing cost is
standing at $ 113,240,556. Based on the economical feasibility study, polyvinyl
alcohol plant is classified to carry low risk with 47.41% ROI before taxes, 1.74
POT before taxs, 55.08% BEP, 43.75% SDP, and 19.07% DCFRR. Considering
the above technical and economical features, it is concluded that polyvinyl
alcohol plant is appealing for further studies. |
