Pra Rancangan Pabrik Pembuatan Asam Linoleat dari Jagung melalui Proses Hidrolisis dengan Kapasitas Produksi 6500 Ton/Tahun dan Tugas Khusus: Rancangan Keteknikan Detail Crystallizer

Abstract

Linoleic Acid (18:2 n-6,2) is an example of a polyunsaturated fatty acid with more than one double bond. It is abundantly found in plant oils such as corn oil, soybean oil, and others. In the body, Linoleic Acid is converted into Gamma Linoleic Acid (GLA), an essential fatty acid that cannot be synthesized by the body itself. Corn (Zea mays L.) is one of the most crucial food commodities after rice and is also a strategic crop for the national economy. The pre-design of the plant for producing Linoleic Acid from corn through a hydrolysis process has a capacity of 6,500 tons/year. The factory operates for 330 days a year and requires 37,533.4812 kg/hour or 900.8035488 tons/day of corn raw materials. The process involves using a filter press to extract oil from corn seeds and for water degumming to remove gum from the raw corn oil, resulting in clean corn oil. Continuous high-pressure splitting is employed to obtain fatty acids from corn oil, achieving a 99% pure hydrolysis conversion. The process does not use a catalyst and has a shorter hydrolysis time, operating at 280°C and 50 atm with a Reactive Distillation Column. For separating the fatty acids, two crystallizers are used: a Low Temperature Isothermal Crystallizer utilizing R-134a. The factory is planned to be located in PT Kawasan Industri Gresik, with a land area of 24,000 m². Water needs for the factory will be sourced locally. The business entity is planned to be a Limited Liability Company (PT), and the organizational structure will be a line organization with a required workforce of 167 people. The results of the analysis of the economic aspects obtained are as follows: • Capital Investment (CI) = $34,781,231.30 • Total Cost (TC) = $122,606,246.64 • Profit Margin (PM) = 19% • Break Even Point (BEP) = 36.63% • Return On Investment (ROI) = 206% • Pay Out Time (POT) = 4 years 1 month • Internal Rate of Return (IRR) = 40.5%
