Pra Rancangan Pabrik Monoetilen Glikol dari Etilen Oksida dan Karbondioksida Menggunakan Proses Karbonasi dengan Kapasitas Produksi 105.000 Ton/Tahun

Abstract

Ethylene glycol is one of the chemicals whose production has not yet met the needs of industries in Indonesia. Most ethylene glycol is used as a raw material in the polyester industry, which is a primary raw material for the textile and plastic industries. The production of ethylene glycol is typically carried out through the direct hydrolysis of ethylene oxide, but this process has several drawbacks, including low ethylene glycol conversion rates. Therefore, to maximize ethylene glycol production, it is proposed to produce ethylene glycol from ethylene oxide using the carbonation process.This production process consists of several stages: the initial stage, the carbonation stage, and the hydrolysis stage. The ethylene glycol plant is planned to be located in Pedamaran, Pekaitan, Rokan Hilir Regency, Riau, on a 21,126.60 m² site, with a production capacity of 105,000 tons per year. The plant will operate 24 hours a day for 330 working days per year and employ 175 workers. The business structure of this ethylene glycol plant is a limited liability company (PT).The establishment and operation of the plant require an investment capital of IDR 1,071,132,324,144 and production costs of IDR 794,854,143,387. Based on the feasibility analysis, the plant has a BEP (Break-Even Point) of 41.9878%, an ROI (Return on Investment) of 17.8740%, a POT (Pay-Out Time) of 5 years and 7 months, an RON (Rate of Net Return) of 29.79%, and an IRR (Internal Rate of Return) of 17.4714%. Based on the economic analysis, it can be concluded that the preliminary design of the monoethylene glycol plant from ethylene oxide and carbon dioxide using the carbonation process is feasible to establish.
