Prarancangan Pabrik Pembuatan Surfaktan Sodium Lignosulfonat dari Sekam Padi dengan Metode Delignifikasi Organosolv dengan Kapasitas Produksi 14.728,94 Ton/Tahun

Abstract

The proposed plant will operate for 330 days a year. The main process in this proposal consists of three stages, namely delignification stage, lignin isolation stage, and sulfonation stage. In the delignification stage, an organosolv process is applied using an organic solvent in the form of ethanol as the cooking solution. While in the sulfonation stage, the operation is carried out at 150°C for 1 hour. The amount of rice husk required to achieve the annual production capacity is 7.087,6868 kg/hour. The sodium lignosulfonate surfactant manufacturing plant from rice husk is planned to be established in Deli Serdang Regency, North Sumatra 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 on this design are as follows: 1. Capital Investment (CI) = Rp1.087.591.378.291 2. Total Cost (TC) = Rp771.345.438.118 3. Profit Margin (PM) = 18,49% 4. Break Even Point (BEP) = 40,10% 5. Return on Investment (ROI) = 10,62% 6. Return on Network (RON) = 17,69% 7. Pay Out Time (POT) = 9,42 tahun 8. Internal Rate of Return (IRR) = 7,845% Based on the economic analysis, it can be concluded that the sodium lignosulfonate surfactant plant from rice husk with oraganosolv delignification process is feasible to be established
