Abstract
Acetonitrile Plant from Acetic Acid and Ammonia with Acetic Acid Ammoniation Process at a production capacity of 60,000 Tons/year. This plant will operate 365 days a year. The Acetonitrile manufacturing process prepares Acetic Acid raw materials from PT Indo Acidatama and Ammonia from PT Petrokimia Gresik. Liquid acetic acid is evaporated and heated gradually using a heat exchanger and compressor until it reaches a temperature of 360°C and a pressure of 3.1 atm. Liquid ammonia is also evaporated, expanded, and heated until it reaches a gaseous state at a temperature of 360°C and a pressure of 3.1 atm. Both materials are fed into a fixed bed multitube reactor with the help of a γ-alumina catalyst at a mole ratio of 1:1. This endothermic reaction operates at a pressure of 3.1 atm and a temperature of 360°C with a reaction conversion reaching 98%, producing a mixture of acetonitrile gas, water, residual acetic acid, and ammonia. The reactor output gas stream is expanded and cooled to 30°C at 1 atm pressure, then fed into a stripper to separate the remaining ammonia gas. The liquid from the bottom of the stripper is heated to 93.9°C and fed to Distillation Tower I to separate the bottom product, acetic acid, from the top product, a mixture of acetonitrile and water. This top product is then processed in Distillation Tower II using extractive distillation with the addition of ethylene glycol as an entrainer at 85°C. Distillation Tower II produces acetonitrile with a purity of 99% as the main product at the top. The bottom product from Distillation Tower II, a mixture of water and ethylene glycol, is fed to Distillation Tower III to separate the water for the waste treatment unit, while the ethylene glycol is recycled as an entrainer. The acetonitrile plant is planned to have a production capacity of 60,000 tons/year and will be built on 78,078 m² of land located in the Wijaya Kusuma Industrial Estate, Semarang. The company is a Limited Liability Company (PT) with a Line and Staff organizational structure. The plant operates continuously 24 hours a day, 365 days a year. The project is designed with a two-year construction period and an estimated equipment life of 10 years. Financially, the total required investment (Total Capital Investment / TCI) is IDR 6,252,719,543,287.96, divided into fixed capital (FCI) of IDR 4,367,360,022,050.43 and working capital (WCI) of IDR 1,885,359,521,237.53. For its annual operations, the factory requires raw material costs of Rp 3,522,801,670,191.97 and utility costs of Rp 594,203,359,372.576, resulting in a total annual production cost (TPC) of Rp 7,742,221,769,626.91. From this production, the estimated potential sales revenue reaches Rp 10,613,971,397,971 per year. Based on an economic feasibility analysis, assuming a bank loan interest rate of 13%, this factory demonstrates highly profitable economic indicators. The pre-tax rate of return (ROI) is 34% and the after-tax rate is 26.55%. The Internal Rate of Return (IRR) is 23%, with a payback period of 3 years and 12 months, and a break-even point (BEP) of 35%.
