Prarancangan Pabrik Vanilin Dari Eugenol Kapasitas 5.000 Ton / Tahun
Vanillin was made through three stages. The first stage is reaction of eugenol with NaOH to form sodium isoeugenol. Sodium isoeugenol formation reaction takes place in an isothermal condition (150°C and 3.5 atm) in the isomeration reactor (RATB-01). The second stage is reaction of sodium isoeugenol...

| Summary: | Vanillin was made through three stages. The first stage is reaction of eugenol with NaOH to form sodium isoeugenol. Sodium isoeugenol formation reaction takes place in an isothermal condition (150°C and 3.5 atm) in the isomeration reactor (RATB-01). The second stage is reaction of sodium isoeugenol with nitrobenzen to form sodium vanillate in the oxydation reactor(RATB-02) at 150°C and 3.5 atm. The third stage is the reaction of sodium vanillate with HCl in the netralization reactor (RATB-03) to form vanillin product. Vanillin plant is planned to be established in Cilegon, West Java with in the area of 21,000 m2 and requires 164 workers. The plant is designed with a capacity of 5,000 tons/year and operated continuously for 330 days/year. To produce 5,000 tons/year vanillin and 921.927 tons/year ethylene,it requires 7935.273 tons/year eugenol, 5020.757 tons/year nitrobenzene, 2179.23 tons/year NaOH and 1486,982 tons/year HCl. The requirement of heat is 5390,5 kJ/h, and 35,070.56 kg/hour water. To establish this plant, it needs fixed capital US$ 8,384,656.19 and Rp689.091.260.225,76 and US$945,254.86 and Rp324.756.087.768,78 working capital. Profits earned before tax is Rp 195.823.621.550,75/year and profit after tax is Rp97.911.810,775 /year. From the calculations, Return on Investment (ROI) before taxes 25.41%, Return on Investment (ROI) 12.70% after tax, Pay Out Time (POT) before taxes 3.78 years, Pay Out Time (POT) after tax 7.29 years, 46.93% Break Even Point, Point Shut Down 34.79% and Discounted Cash Flow Rate of Return 17.47%. Based on the evaluation, the vanilline plant with a capacity of 5.000 tons/year is quite interesting to be studied further |
