ABSTRACT
Acrylonitrile has the potential to be used as an additive in the chemical
industry including the manufacture of thermoplastics, adiponitrile for the nylon
industry, acrylamide, resin, synthetic rubber, acrylic fibers for the acrylic fabric
industry and ABS (Acrylonitrile Butadiene Styrene) resin for the manufacture of
plastic goods. Acrylonitrile is produced by the Sohio process using propylene,
ammonia and air as raw materials. The acrylonitrile plant operates for 300 days
per year in 24 working hours per day with a production capacity of 128,000
tons/year. This factory produces acrylonitrile with a purity of 99.47% as the main
product while the by-products are acetonitrile and hydrogen cyanide. The
location for the establishment of the acrylonitrile plant is planned in the Basilam
Baru area, Sungai Sembilan District, Dumai City, Riau Province. The design of
the main tool of the absorber column (A-101) is useful for separating ammonia
gas that is not completely converted from the resulting product using sulfuric acid
as a solvent. This absorption process will produce Ammonium Sulphate. The
absorber column with the packed bed column type has a height of 4.2084 m with a
column diameter of 0.5588 m. The type of packing used is a rasching ring made of
ceramic with a torispherical flanged dished head. Fixed Capital Investment (FCI)
of this acrylonitrile plant is $ 59,018,469.7 and Working Capital Investment is
15% of Total Capital Investment (TCI) of $ 10,415,024.1 so that the Total Capital
Investment (TCI) value is $ 69,433,493 ,7. Total Production Cost of the
acrylonitrile plant was $226,071,844.0 while the net profit after tax was 35%
which was $406,667,476. Return on Investment (ROI) after tax is 59.54%, pay out
time (POT) is 1.57 years and break event point (BEP) is 35%. The IRR value of
the acrylonitrile factory is 22.67% greater than the bank's RRR value of 22.55%,
and the Net Present Flow (NPV) value of $ 2,504,738,736.6 is greater than the
Total Capital Investment (TCI) value. From the economic analysis, the
acrylonitrile plant is feasible to establish.
