| Summary: | The plant of which 30.000 ton/year of amyl alcohol as the prominent product and 15.525 ton/year of amilen as the side product is made by reacting the basic material of amyl chloride for 63.371,8 ton/year and 48% of NaOH for 51.186,2 ton/year aided by sodium oleic as the catalyst for 1800,8 ton/year. A utility unit as the supporting unit in the production process of this plant includes water, steam, electricity, and pneumatic. The utility needs NaCl for 15.523,2 kg/year, NaOH for 9.187,2 kg/year, Na2CO3 for 250.905,6 kg/year, coagulant for 17067,6 kg/year, Na2HPO4.2H2O for 22.096,8 kg/year, fuel (diesel type) for 118.742,4 liter/year, boiler fuel (fuel oil type) for 9.904.277 liter/year, and electricity for 505,2 kW. This plant has 200 employees. The land of this plant is 30.000 m2. This plant is located in Cilegon. The fixed capital of this plant is $ 23.611.397,49 or Rp 224.308.276.150 and the working-capital is $ 28.050.017,63 or Rp 266.475.167.555. From the result of economic analysis, it can be obtained that the break event point (BEP) is 46,5 %. Whereas, the pay out time (POT) before tax is 2,068 years, while after tax is 3,029 years. Furthermore, the return on investment (ROI) before tax is 38,37 % and after tax is 23,02%. In addition, the discounted cash flow is 20,549 %.
