Indonesia is a developing country that continues to experience improvements in various sectors, especially the industrial sector. One of the industries that has the potential to encourage economic growth in Indonesia is the polyester industry. Ethylene glycol is a chemical compound with the molecular formula C2H6O2, 97.34% ethylene glycol is used as a raw material for polyester fiber and the remaining 2.66% is used as an additional raw material for making brake fluid, paint, ballpoint ink, solvents or solvents, foam stabilizers, cosmetics, and anti-freeze ingredients. In this plant design, ethylene oxide and CO2 are used as raw materials through the carbonation process. This process is carried out in a multitube fixed bed reactor with the help of a molybdenum catalyst, at a pressure of 14.5 bar and a temperature of 90 ⁰C. The reactor operates adiabatically and the reaction is exothermic. The ethylene glycol formed is purified using separation based on pressure differences, namely flash drums and evaporators to remove water content to produce products with a purity of 98.20% with a quantity of 43,000 tons / year. This plant is planned to be built in Serang, Banten on an area of 20,300 m2. The number of employees required is 234 people. The economic evaluation results obtained a net profit of Rp. 37,940,384,592.262 from sales. Return on investment (RoI) is 14.59%, Pay out time (POT) is 4.07 years and break-even point (BEP) is 42.15%. Based on the economic evaluation, the ethylene glycol plant is feasible to build.
