Prarancangan Pabrik Pembuatan Etilen Oksida Menggunakan Metode Oksidasi Etilen Berkapasitas 1.400 Ton/Tahun

Abstract

Ethylene oxide is the simplest cyclic ether, colorless with a sweet ether-like aroma, and serves various functions as a disinfectant, sterilizing agent, and fumigant. Additionally, it is used as a raw material in the production of several derivative compounds, such as monoethylene glycol, diethylene glycol, and polyethylene glycol. In Indonesia, the growing demand for ethylene oxide is still met through imports, making it necessary to establish an ethylene oxide plant to fulfill domestic needs. This plant design employs the direct oxidation method between ethylene and oxygen, with a production capacity of 1,400 tons per year, operating 300 days annually. The production process consists of four stages: raw material preparation, oxidation reaction, CO₂ processing, and product purification. The proposed plant will be located in the Sei Mangkei Special Economic Zone (KEK), North Sumatra, on a site covering 14,826 m² and will require 200 employees. The business entity will be a limited liability company (PT). The economic evaluation shows a capital investment (CI) of IDR 375.46 billion, a total production cost (TPC) of IDR 210.25 billion, and revenue of IDR 281.45 billion, with a net profit of IDR 47.40 billion. The profit margin is 16.84%, return on investment (ROI) is 12.62%, and the internal rate of return (IRR) is 9.36%. The project is expected to reach its break-even point (BEP) at 50.45% of capacity, with a payback period (POT) of 7 years and 11 months. Based on the economic analysis, this plant design is deemed feasible for implementation.
