The need for caprolactam is increasing every year, while the availability of caprolactam in the country is non-existent. Until now, the need for caprolactam in Indonesia is met by importing it from other countries, such as China, Japan, India, Hong Kong and the United States. Over the last four years, imports of caprolactam have been relatively large, namely around 29,000 tons to 35,000 tons per year. The need for caprolactam in Indonesia is quite high and continues to increase along with increasing demand from industrial users. The establishment of a caprolactam factory is one way to fulfill and supply raw materials for making nylon-6, amino caproic acid plastic and polyurethane. This factory is planned to be established in the industrial area of Gresik City, East Java with a capacity of 30,000 tons/year. The process used in designing the caprolactam factory is the SNIA-Viscosa process, where melted benzoic acid, hydrogen and palladium catalyst are reacted in a hydrogenation reactor at a temperature of 170°C and a pressure of 16 atm to form cyclohexane carboxylic acid. Cyclohexane carboxylic acid is then mixed with an oleum catalyst and reacted with nitrosylsulfate acid in a nitrosation reactor to form caprolactam at a temperature of 80°C and a pressure of 1 atm. The liquid phase output from the nitrosation reactor is then reacted with water to form sulfuric acid in the hydrolysis reactor. The resulting mixture of caprolactam and sulfuric acid is reacted with calcium hydroxide which has been dissolved in water in a neutralization reactor. The results from the neutralization reactor are filtered using a rotary drum vacuum filter and produce gypsum which is a by-product. The filtrate consisting of remaining benzoic acid, water and caprolactam will be processed into the evaporator to be separated so that the caprolactam will be concentrated. The results from the evaporator will then be fed into the crystallizer so that the final product is formed in the form of caprolactam in crystal form with a final purity of 99%. The economic evaluation review is the basis for the feasibility of establishing a caprolactam factory. Economic analysis aims to determine the feasibility of investing in building a factory. The data used in the analytical study were obtained from literature observations. Analysis is carried out quantitatively through calculation of Pay Back Period (PBP), Internal Rate of Return (IRR), Return of Investment (ROI), Break Even Point (BEP), and sensitivity analysis. The analysis results show that the caprolactam factory has a PBP of 2.77 years, an IRR of 22.763%, an ROI of 26.367%, and a BEP of 44%. Based on the results of the economic evaluation, it can be concluded that the factory is worthy of consideration for its construction.
