ABSTRACT
Ethylene and acetic acid are among the most important petrochemical compounds in the chemical industry, serving as key raw materials for the production of polyethylene, ethylene glycol, styrene, and various other derivative products. Meanwhile, acetic acid is used in the manufacture of adhesives, synthetic fibers (such as acetate), solvents, and as an intermediate in the pharmaceutical and chemical industries. Along with the growth of the plastics, automotive, and textile industries in Indonesia and globally, the demand for ethylene has continued to increase significantly. Based on this opportunity, a plant is designed to produce ethylene and acetic acid with a production capacity of 440,000 tons/year. The main raw material used is ethane, which is obtained through an oxidation process and supplied from Pertamina Balongan. The plant is located in Indramayu City, West Java Province, due to its strategic location near industrial zones and export-import ports, which support logistical efficiency.
The process technology used is the oxidation process, in which the ethylene oxidation reactor (R-102) functions as the main equipment. The reaction takes place in a fixed-bed multitube reactor under conditions of 13.6 atm pressure and a temperature of 260 °C. The utility system includes the supply of water, steam, fuel, electricity, air, instrumentation, and cooling systems. The process control system is equipped with sensors and controllers integrated with safety instruments such as alarms, gate valves, hand valves, check valves, pressure safety valves, and anti-surge control valves. Safety aspects are enhanced through fire protection systems, HAZOP analysis, leak detection, and control systems based on a Distributed Control System (DCS).
Profitability analysis is assessed using the values of Internal Rate of Return (IRR), Return on Investment (ROI), Payback Period (PBP), Break Even Point (BEP), and Net Present Value (NPV), which are 22.71%; 18.53%; 3.9 years; 41.5%; and IDR 36,121,976,305,598, respectively. Sensitivity analysis shows that the NPV is highly affected by three main parameters: raw material prices, Total Capital Investment (TCI), and Total Production Cost (TPC). An increase in raw material prices leads to higher variable costs and reduces profit margins, resulting in a significant decline in NPV. An increase in TCI adds to the initial investment burden, extends the payback period, and suppresses NPV. Meanwhile, an increase in TPC directly impacts the annual net profit, which also leads to a decrease in NPV.
Keywords: Economic Analysis, Ethylene, Plant, Sensitivity, Utilities.
