Abstract
Vanillin Factory from Lignin using Acidification Process with a capacity of 30,000 tons/year, is planned to be established in Serpong, South Tangerang. In the chemical industry, Vanillin is used in the manufacture of lignin, nitrobenzene, sodium hydroxide, hydrochloric acid, and ethyl acetate. This factory will operate 24 hours a day and 330 days a year. The Vanillin Factory uses lignin as raw material obtained from black liquor from PT. Indah Kiat Pulp & Paper. The vanillin manufacturing process begins with mixing lignin, 48% NaOH, and 99.5% nitrobenzene, then pumped to a pressure of 10 bar and heated to 110°C before entering the oxidation reactor for 1 hour, producing vanillin, azobenzene, and impurities. The product is depressurized to 1 bar and separated in a centrifuge; the vanillin is continued to the acidification stage with HCl, then goes through reverse osmosis to remove salt. The vanillin solution is extracted with ethyl acetate, separated, evaporated, and crystallized in a crystallizer, then separated, dried, filtered, and after reaching a size of 100 mesh the vanillin is stored in a storage tank. The provisions for the planned establishment of a vanillin factory are summarized as follows: • Production capacity: 75,000 tons/year • Materials used: Lignin, Nitrobenzene, NaOH, HCl, Ethyl Acetate • Operating system: Continuous • Operating time: 330 days/year; 24 hours/day • Number of employees: 205 people • Company Form: Limited Liability Company (PT) • Organizational Structure: Line and staff Economic Analysis: • Construction period: 3 years • Factory age: 10 years • Utility Cost (1 year): Rp 336,643,082,464 • Fixed Capital Investment (FCI): Rp 648,578,912,646 • Working Capital Investment (WCI): Rp 2,789,015,456,055 • Total Capital Investment (TCI): Rp 3,437,594,368,701 • Total Production Cost (TPC): Rp 16,734,092,736,328 • Bank Interest: 8.00% per year • Internal Rate of Return : 59.36% • Pay Back Period : 2 years 1 month • Break Even Point (BEP) : 24.41%
