ABSTRACT
The acrolein plant is designed with a production capacity of 30,000 tons/year. The raw materials used are propylene and oxygen, aided by the α-Bi₂Mo₃O₁₂ catalyst through the propylene oxidation reaction. The propylene oxidation reaction produces acrolein (C₃H₄O) and by-products such as acrylic acid (C₃H₄O₂), carbon dioxide (CO₂), and water (H₂O). Indonesia's average acrolein import is 38,000 tons/year (BPS, 2023), and the construction of the acrolein plant in Indonesia is expected to meet both domestic and foreign demands. The acrolein plant will be built in Ciwandan District, Cilegon City, Banten Province. Propylene will be supplied by PT Chandra Asri Petrochemical Tbk, and oxygen will be sourced from PT Samator Gas Industri.
The propylene oxidation process occurs in a fixed bed multitube reactor with hitec salt coolant flow. The reactor output will be separated and purified in an absorber column and a distillation column. The acrolein plant requires power of 971.70 kW/hour, steam of 89,480.07 kg/hour, and a total water demand of 116,460.49 kg/hour. The acrolein plant generates liquid and gaseous waste. The liquid waste, totaling 92,179.12 kg/hour, is treated in wastewater treatment facilities, while the gaseous waste is released into the atmosphere. Each piece of equipment in the acrolein plant employs a control system to maintain process variables at setpoint values, with safety ensured through control valves and alarms.
The economic analysis shows a total capital investment (TCI) of IDR 2,083,805,076,164, a working capital investment (WCI) of IDR 312,570,761,425, and a total production cost (TPC) of IDR 1,174,942,676,038. Revenue from acrolein product sales amounts to IDR 2,114,711,294,347/year. The profitability analysis of the acrolein plant is based on return on investment (ROI), payback period (PBP), internal rate of return (IRR), break-even point (BEP), and net present value (NPV). The calculated ROI of the acrolein plant is 24.02%, the PBP is 2.86 years, the IRR is 24.66%, and the BEP is at a production capacity of 36.52%. The NPV of the acrolein plant is IDR 2,949,321,340,634 with a discount rate of 18%. The profitability analysis indicates that the acrolein plant based on the propylene oxidation process is feasible to establish and represents an attractive investment.
