ABSTRACT
Ethylene and acetic acid are among the most important petrochemical compounds in the chemical industry, serving as the primary raw materials in the manufacture 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 both in Indonesia and globally, the demand for ethylene continues to increase significantly. Based on this opportunity, the design of an ethylene and acetic acid plant with a production capacity of 440,000 tons/year was carried out. The main raw material used is ethane, obtained through the ethane oxidation process supplied by Pertamina Balongan. Indramayu City, West Java Province was chosen as the location for the factory construction due to its strategic location, close to industrial areas and export-import ports that support logistical efficiency.
The process technology used is an oxidation process, where the ethane oxidation reactor (R-101) serves as the main tool. Product purification is carried out through two additional distillation columns and an absorber stripper unit for CO2 separation. The utility system includes the provision of water, steam, fuel, electricity, air, instruments, and a cooling system. 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 strengthened through a fire protection system, HAZOP analysis, leak detection, and Distributed Control System (DCS)-based control.
The profitability analysis results are seen from the calculation, with the Internal Rate of Return (IRR), Return on Investment (ROI), Payback Period (PBP), Break Even Point (BEP), and Net Present Value (NPV) values of 22.72%; 18.53%; 3.9 years, 47%; and Rp13,612,411,583,085, respectively. The sensitivity analysis results show that the NPV value is greatly influenced by three main parameters, namely raw material prices, TCI, and TPC. The increase in raw material prices causes an increase in variable costs and decreases profit margins, so that the NPV decreases significantly. The increase in TCI increases the initial investment burden, which extends the payback period and suppresses the NPV value. Meanwhile, the increase in TPC has a direct impact on decreasing annual net profit, which also results in a decrease in the NPV value.
