Pra Rancangan Pabrik Pembuatan Bioavtur dari Crude Palm Oil (CPO) dengan Proses Universal Oil Product (UOP): Kapasitas 100.000 Ton/Tahun dan Tugas Khusus Rancangan Keteknikan Detil Reaktor Hydrotreating

Abstract

Factory design for the production of biojet fuel from crude palm oil (CPO) using the universal oil product (UOP) process has a capacity of 100,000 tons per year and operates for 330 days per year. The main process in this factory design consists of three stages: raw material pretreatment stage, universal oil product (UOP) reaction stage, and product purification stage. In the reaction stage, hydrotreating and hydrocracking reactions are conducted using a fixed bed multitube reactor operating at temperatures of 332°C and 398°C for 0.29 hours. The required amount of CPO to achieve the annual capacity is 25,104.310 kg/h. The specific task completed is the detailed engineering design of the hydrotreating reactor. The designed reactor has the following specifications: • Shell and head diameter: 2.61143 m • Shell height: 5 m • Head height: 0.50112 m • Shell thickness: 0.00508 m • Head thickness: 0.00624 m • Outer tube diameter: 0.02971 m • Tube thickness: 0.00419 m • Tube length: 5 m • Number of tubes: 2531 tubes • Insulator thickness: 0.02559 m • Construction material: Carbon steel SA-283 Grade C The biojet fuel production plant from CPO using the UOP process is planned to be established in Simalungun Regency, North Sumatra Province, with a total plant area of 29,000 m2. The water requirement for the plant is supplied from Sungan Boh Bolon at a rate of 89,372.2913 kg/h. The organizational structure consists of line and staff organization with a total of 239 employees. The results of the economic analysis for this factory design are as follows: 1. Total Cost (TC): Rp. 4,837,609,835,449.16 2. Profit Margin (PM): 16.41% 3. Break Even Point (BEP): 36.97% 4. Return On Investment (ROI): 11.28% 5. Pay Out Time (POT): 8.87 years 6. Return On Network (RON): 18.79% Based on the economic analysis results, it can be concluded that the biojet fuel production plant from crude palm oil (CPO) using the Universal Oil Product (UOP) process is not feasible to be established.
