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
