Abstract

Cyclohexane is a intermediate product which is used as raw material of adipic acid and caprolactam which will be processed into nylon 6,6 and nylon 6. This cyclohexane plant is planned to be established in Krakatau Steel Cilegon Banten Industrial Estate with a design capacity of 30,000 tons / year. The process of making this cyclohexane using hydrogenation process. The reaction takes place inside the multitube fixed bed reactor in the gas-liquid phase with the help of a nickel catalyst. The operating conditions of the reactor are designed at a pressure of 20 atm and a temperature of 150°C. Needs of benzene as much as 7,489,2838 kg / hour, hydrogen needs as much as 1,352,6713 kg / hour, and catalyst needs as much as 5,792.6796 kg. The source of water used is from Nadra Cilegon Reservoir in Banten. The cooling water requirement is 101,818,8969 kg / hour, the water requirement for steam is 2,048,9580 kg / hour, and the domestic water needs is 1,173,4598 kg / hour. Electricity requirement for process equipment is 2,124,7044 kw, electricity need for utility appliance as much as 109,6179 kw, and general electricity requirement as much as 195 kw. Fuel requirement for boiler is 155,3 liter / hour and fuel requirement for electricity generator for 7 days is 58,536,5911 liter. Needs compressed air as much as 44,0384 m3 / hour. The form of business entity in the cyclohexane plant preparation is a limited liability company. The cyclohexane plant operates for 330 days a year with 133 employees. This cyclohexane plant requires a fixed capital of Rp 343,094,440,016.21 and working capital of Rp 548,342,887,684,46. From the factory economic analysis, the profit before tax is Rp 139,916,212,692,37 per year and profit after tax of Rp 104,937,159,519,27 per year with tax deduction of 25%. Percent return on investment before tax 40,78% and after tax 30,59%. Pay out time before tax of 1.97 years and after tax of 2.46 years. Break even point of 40.15%, Shut down point of 25.47%, and Discounted cash flow of 13.81%.
