Pra Rancangan Pabrik Pembuatan Bio-Oil dari Tongkol Jagung (Zea Mays) melalui Proses Pirolisis Katalitik Menggunakan Katalis Ni/NZA dengan Kapasitas 40.000 Ton/Tahun

Abstract

This preliminary design for a catalytic pyrolysis bio-oil production plant, utilizing corn cobs (Zea Mays), is planned with a production capacity of 40,000 tons per year and will operate for 330 days annually. The main process in this plant design comprises four stages: raw material preparation, pyrolysis, primary product separation and purification, and byproduct separation and purification. A fluidized bed reactor is employed for the pyrolysis stage, operating at 500°C and 4 atm for 1 minute with a 2% Ni/NZA catalyst concentration. To achieve the production capacity of 40,000 tons of bio-oil per year (or 5,050.5051 kg/hour), the plant will require 33,609.3137 kg/hour of corn cobs (Zea Mays). The bio-oil production plant, using corn cobs (Zea Mays) and the pyrolysis process, is planned to be established in Rejoso Lor Village, Rejoso District, Pasuruan Regency, East Java, with a total plant area of 16,643 m². Water for the plant will be supplied from the Rejoso River in Pasuruan Regency, East Java, at a rate of 41,279.74 kg/hour. The planned organizational structure for the company is a Limited Liability Company (PT) with a line and staff organizational chart, employing a total of 200 employees. The economic analysis results for this plant's preliminary design are as follows: 1. Capital Investment (CI): Rp 1,994,512,142,578,- 2. Total Cost (TC): Rp 3,305,393,058,277,- 3. Sales Revenue: Rp 4,055,691,115,823,- 4. Net Profit: Rp 463,615,050,535,- 5. Profit Margin (PM): 17.5749% 6. Break-Even Point (BEP): 44.3274% 7. Return on Investment (ROI): 23.2445% 8. Return on Net Worth (RON): 38.7409% 9. Pay Out Time (POT): 4 years 4 months 10. Internal Rate of Return (IRR): 25.1779% Based on the economic analysis, it can be concluded that the catalytic pyrolysis bio-oil production plant, utilizing corn cobs (Zea Mays) with a production capacity of 40,000 tons per year, is feasible for establishment.
