ABSTRACT
Phthalic anhydride (C8H4O3) is a chemical used in the manufacture of plastics and
polymers. One of its main applications is as a raw material for the production of
plasticizers, unsaturated polyester resins, alkyd resins, and other derivative products.
Indonesia's phthalic anhydride needs are met by PT Petrowidada in Gresik, Indonesia,
with a production capacity of 70,000 tons/year, and imports from various countries, such
as Brazil, China, the USA, Australia, and Germany. Therefore, establishing a phthalic
anhydride plant in Indonesia can reduce dependence on imports while increasing state
revenue. The phthalic anhydride plant was established in Remen Village, Jenu District,
Tuban Regency, East Java Province, in 2030, with a production capacity of 62,000
tons/year.
The phthalic anhydride production process uses the von Hayden process. This process
uses oxylene and oxygen as raw materials with a vanadium pentoxide (V2O5) catalyst.
The von Hayden process operates using a fixed-bed multitube reactor at a pressure of 1.7
atm and a temperature of 360°C, producing phthalic anhydride as the primary product
and several by-products such as maleic anhydride and water. The phthalic anhydride
plant's utility needs include a water supply unit and a steam supply unit.
The phthalic anhydride plant has a fixed capital investment (FCI) of
Rp1,084,408,585,529.91, a working capital investment (WCI) of
Rp191,366,220,975.87, and a total capital investment (TPC) of
Rp1,183,438,539,275.61. The profitability analysis of the phthalic anhydride plant
yielded a net present value (NPV) of Rp2,246,098,467,319.36, an investor’s rate of return
(IRR) of 22.48%, and a payback period (PBP) of 2.5 years. Based on these results, the
phthalic anhydride plant design is considered feasible to be established and is a profitable
investment.
Keywords: Flash Separator, O-Xylene, Phthalic Anhydride, Profitability Analysis, Von
