| dc.description.abstract | Indonesia’s ethylene oxide imports are projected to reach approximately 3,000 tons in 2028, indicating increasing dependence on foreign supply and the need for domestic production capacity. This study presents the preliminary design of an ethylene oxide plant with a capacity of 3,000 tons per year using the ethylene oxidation process with air. The production sequence consists of feed preparation, oxidation reaction over a silver catalyst in a multitubular fixed-bed reactor, carbon dioxide removal, and product purification. The design scope includes mass and energy balance calculations, equipment and utility design, site selection, and economic evaluation. The results show that production requires 373.92 kg/hour of ethylene, equivalent to 2.69 million kg per year, supported by 26 process equipment units and 20 utility units. The plant is proposed to be located in the Sei Mangkei Special Economic Zone, requiring 13,590 m² of land, organized as a Limited Liability Company employing 200 workers. The economic analysis indicates a Capital Investment of IDR 437.76 billion, Total Production Cost of IDR 204.36 billion, a Profit Margin of 44.38%, a Break Even Point of 14.48%, an ROI of 62.62%, a RON of 103.77%, a Pay Out Time of 1 year 7 months, and an IRR of 26.31%. These results confirm that the proposed plant is technically and economically feasible. | en_US |
