ABSTRACT
Cyclohexanol is an intermediate compound that plays a vital role in the chemical industry, particularly as a primary raw material in the production of nylon 6 and nylon 66. As the textile and plastic industries continue to grow both in Indonesia and globally, the demand for cyclohexanol has consistently increased. In response to this opportunity, a cyclohexanol plant is designed with a production capacity of 21,000 tons per year. The main raw material used is cyclohexene, which is obtained through the dehydrogenation of cyclohexane imported from Reliance Industries Limited Corporate, India. Dumai in Riau Province is selected as the plant location due to its strategic position near industrial zones and export-import ports, which supports logistical efficiency.
The process technology implemented is direct hydration of cyclohexene using a reactive distillation system, with the reactive distillation column (T-201) serving as the main equipment. Product purification is carried out through two additional distillation columns and a decanter unit for liquid–liquid phase separation. The utility systems cover the provision of water, steam, fuel, electricity, instrument air, and cooling systems. Liquid waste is treated through a physical–chemical treatment unit, while hydrogen gas (H₂), as a by-product from the dehydrogenation process, is vented directly into the atmosphere via a flare system. The process control system is equipped with sensors and controllers integrated with safety instruments such as alarms, gate valves, hand valves, check valves, pressure safety valves, and anti-surge control valves. Safety aspects are reinforced through fire protection systems, HAZOP analysis, leak detection, and centralized control via Distributed Control System (DCS).
Economic analysis based on calculations yields the values: Internal Rate of Return (IRR), Return on Investment (ROI), Payback Period (PBP), Break Even Point (BEP), and Net Present Value (NPV) respectively 28.76%, 23.45%, 3.11 years, 56.64%, and Rp 9.724.683.369.158,0. Sensitivity analysis shows that the NPV is highly influenced by three key parameters: raw material price, Total Capital Investment (TCI), and Total Production Cost (TPC). An increase in raw material price leads to higher variable costs and lower profit margins, resulting in a significant reduction in NPV. A rise in TCI value adds to the initial investment, which extends the payback period and suppresses the NPV. Meanwhile, an increase in TPC directly reduces annual net profit, which in turn decreases the NPV. Therefore, maintaining raw material price stability, as well as ensuring efficiency in capital usage and production cost control, are crucial factors for the long-term feasibility and success of the project.
