Prarancangan Pabrik Pembuatan Surfaktan Sodium Lignosulfonat dari Sabut Kelapa dengan Metode Delignifikasi Organosolv Kapasitas Produksi 20.000 Ton/Tahun (Tugas Khusus: Rancangan Proses Delignifikasi Metode Organosolv)

Abstract

Pre-design of sodium lignosulfonate manufacturing plant from coconut fiber using a delignification process of organosolv it has a capacity of 20,000 tons/year and operates 330 days a year. The main process in this pre-design consists of four stages, which is, the raw material preparation stage, the delignification stage, the lignin isolation stage, and the sulfonation stage. At the delignification stage, a process is applied organosolv by using an organic solvent in the form of methanol as a cooking solution. Meanwhile, in the sulfonation stage, the operation is carried out at a temperature of 90°C for 1 hour. The amount of coconut fiber required to reach annual production capacity is 6,259.2368 kg/hour. The factory for making sodium lignosulfonate surfactant from coconut fiber is planned to be established in Rokan Hilir Regency, Riau Province, with a total area of 22,545 m2. The planned form of company organization is a Limited Liability Company (PT) with a total of 179 employees. The results of the economic analysis of this pre-design are as follows: 1. Capital Investment (CI) = Rp983.278.131.893 2. Total Cost (TC) = Rp692.024.984.476 3. Profit Margin (PM) = 23,35% 4. Break Even Point (BEP) = 37,74% 5. Return on Investment (ROI) = 15,26% 6. Return on Network (RON) = 35,43% 7. Pay Out Time (POT) = 6 year 7 month 8. Internal Rate of Return (IRR) = 14,289% Based on economic analysis, it can be concluded that the design of a sodium lignosulfonate surfactant factory from coconut fiber using a delignification process oraganosolv this is worth establishing.
