× ABSTRACT Nesia Angela Cristi, Desti Dwi Nurrokhimah, 2014, Preliminary Design of Isopropyl Alcohol Plant from Propylene and Water Capacity 40,000 Tons/Year, Chemical Engineering, Sebelas Maret University, Surakarta. Isopropyl alcohol (C3H7OH) is a colorless, volatile, and flammable liquid. Isopropyl alcohol can be used as solvent, additional chemicals in agriculture, additional chemicals in pharmacy, and antiseptic as well as is consumed in the production of acetone, methyl isobutyl ketone, methyl isobutyl carbinol, isopropylamine, and isopropyl acetate. Isopropyl alcohol plant from propylene and water will be built on Cilegon industrial area, Banten on 2018 with 40,000 tons/year capacity. Isopropyl alcohol is produced by treating propylene with water at 145,67 °C - 148,02 °C and 78,95 atm in a trickle bed reactor at adiabatic condition. The molar ratio of propylene and water is 1 : 12. The reaction operates in exothermic reaction and gas-liquid phase. The feeds used are propylene with purity of 99.5 wt percent (48.530,195 tons/year), water (237.104,664 tons/year) and Amberlyst DT as catalyst (11.323,509 tons/year). The main products are isopropyl alcohol with purity of 99 wt percent, water impurity and diisopropyl ether. The by products are diisopropyl ether with purity of 97 wt. The utilities including water (process water, cooler water, boiler feed water, drinking water, and sanitized water) from PT Krakatau Tirta Industri (PT. KTI) which located in Cilegon industrial area. The water consumption rate is 800.065 m3/hour and steam consumption rate is 97,070.687 lb/hour. The electricity usage is 818.13 kW from Perusahaan Listrik Negara (PLN). The fuel consumption rate from IDO (Industrial Diesel Oil) is 284.239 liter/hour. And the pressurized air consumption rate is 44.174 m3/hour. There are 3 laboratories, physical, analytical and research, and development laboratory. The type of company is chosen as Private Limited with line and staff structure. The company employs 137 people. Economic analysis shows that the Return of Investment (ROI) is 56.54% before tax and 39.58% after tax. Pay Out Time (POT) is 1.5 year before tax and 2.02 year after tax. Break Even Point (BEP) is 41.87%, Shut Down Point (SDP) is 27.48% and Discounted Cash Flow (DCF) is 17.20%. These data show that isopropyl alcohol plant can be established.
