| Summary: | Polystyrene is a polymer substance made from monomer styrene which
leads to production of casing, insulator, food-wrapper and resin. The opportunity
of polystyrene industry to develop in Indonesia is quite big, by considering the
fact that in 2011, the value of Indonesian product resulted from import activity
has reached 45.309 ton in total.
The factory is designed to operate for 330 days/year consecutively with
polystyrene production capacity of 50.000 ton/year. The main raw material
needed is styrene monomer 50.468,284 ton/year, ethylbenzene 1.286,1804 to/year,
and benzoyl peroxide 58,6389 ton/year. The production of polystyrene involving a
reaction of addition polymerization and is done by polymerization solution
method. Generally, polymerization production follows these sequent steps, which
are: (i) reaction between styrene monomer, ethylbenzene and benzoyl peroxide
inside a continuous stirred tank reactor, (ii) separation of polymerization product
by one stage distillation process, and (iii) compaction process of polystyrene by
using extruder. As a support for these activities, utility unit will supply the need of
cold water 53.628,2688 kg/hour, electricity 914,98 kVA, and steam 1856,0295
kg/hour.
The factory will be built in Cilegon which is located in Banten province.
This decision made by considering the raw material oriented. Cilegon area is
located close to both monomer styrene industry and harbor which will help the
distribution of polystyrene production way much easier. Besides, the location of
the factory is also close to a river. Therefore the river will supply the water source
for the utility unit.
The calculation of economy evaluation gives result in $24.060.164,71 of
the fixed capital and $16.402.314,40 of the working capital. When the capacity
production reaches 80% , the ROI before tax achieved will be 31,01% and ROI
after tax 15,51% |
