| dc.description.abstract | Preliminary design of TBA with capacity 60.000 ton/year is plant to be
built in Cilacap, Central Java in the area of land 3 ha. This chemical plant will be
operated for 330 dah/year or 24 hours a day with 200 employees.
Row material neededs is isobuthylene 99.952.147,84 kg/year, the
production process will be operated at temperature 70°C, at pressure about of 11
atm using Fixed Bed Multitube Reactor with yield 70 %. The utility consist of
169.234 kg/hour of cooling water; 2.408,3333 kg/hour of housing water;
1.467,3635 kg/hourofsteam; 19,8045 It/hour of Industrial Diesel Oil (IDO) while
the powerof electricity of about 270 Kwh provided by PLN. This chemical plant
also use generator set as reserve.
Economic analysis shows thats this chemical plant need to be covered by
fixed capital of about US$ 11.172.937,93; working capital of about US$
16.631.640,16. The profit before tax is US$ 7.754.499.32 while the profit aftertax
is 4.652.699.59 Percentage of return on investment (ROI) before tax is 69,40%
while after tax is 41,64%. Pay out time (POT) before tax is 1,25 years while after
tax is 1,93 years. The value of break even point (BEP) is 41,08% and shut down
point (SDP) is 27,84% with Discounted Cash Flow Rate (DCFR) is 25,22%.
Based on the economic analysis, it is concluded that plant design of TBA with
capacity 60.000 ton/years visible to be built. | en_US |
