Abstract
Methyl acetate is an important chemical widely used as a solvent in the paint, ink, adhesive, pharmaceutical, and chemical industries. The demand for methyl acetate in Indonesia continues to increase, while domestic consumption is still largely fulfilled through imports. Therefore, the establishment of a methyl acetate plant is expected to meet domestic demand, reduce import dependency, and enhance the added value of the national chemical industry. The proposed plant has a production capacity of 50,000 tons/year and is located in the Karanganyar Industrial Estate, Central Java, considering the availability of raw materials, utilities, transportation access, and product distribution. The production process employs the esterification of acetic acid and methanol using homogeneous sulfuric acid as the catalyst integrated with a reactive distillation system. Methanol is first vaporized in a vaporizer and then separated in a flash drum, where the liquid methanol is recycled while the methanol vapor is compressed and fed to the lower section of the reactive distillation column. Acetic acid and sulfuric acid are preheated before being introduced into the upper section of the reaction zone. The overhead product from the reactive distillation column is methyl acetate with a purity of 99.85%, whereas the bottom stream is further processed in a second distillation column to recover methanol for recycling, while the bottom stream is sent to the wastewater treatment unit. The plant is designed for continuous operation for 330 days/year and 24 hours/day, requiring 5,506.933 kg/h of methanol, 5,214.898 kg/h of acetic acid, and 51.627 kg/h of sulfuric acid catalyst. Economic evaluation indicates a Fixed Capital Investment (FCI) of IDR 1,219,195,871,658, a Working Capital Investment (WCI) of IDR 468,036,523,538, and a Total Capital Investment (TCI) of IDR 1,687,232,395,196. The project achieves a Return on Investment (ROI) of 38.12% before tax and 28.59% after tax, an Internal Rate of Return (IRR) of 16.4%, a Payback Period (PBP) of 4 years and 1 month, and a Break Even Point (BEP) of 34%. These technical and economic evaluations indicate that the proposed methyl acetate plant utilizing reactive distillation is technically feasible and economically viable.
