Abstract

In Indonesia, propylene glycol plant is an industry that can provide a good opportunity for the country. Propylene glycol is produced by a reacting of propylene oxide and water using an acid catalyst by a ratio of propylene oxide: water: methanol is 43.04: 802.8: 71.87 lbmol. The process using CSTR reactor (Continuous stirred tank reactor). The reactor operates at temperature of 30°C and a pressure of 1 atm. The reaction in the reactor is carried out at liquid phase, irreversible, and exothermic condition. Supporting units of the plant consists of the units of the water provider, the unit of steam supply, electricity and fuel needs, and laboratories to maintain the quality of materials and products to conform to the standards. This company is a limited liability company (PT) with a system of ganizational structure and staff. The company is located in Gresik Java Province. The economic analysis showed that Pretax Percent Return on Investment (ROI) is 25.42 % and ROI after tax is 17.79 %. Pay out Time (POT) before taxed is 2.8 year. Break Even Point (BEP) of 45.96 %, Shut down Point (SDP) of 21.51 %, and was obtained Discounted Cash Flow (DCF) of 30.28 %, were obtained the data feasibility analysis, it can be concluded that the plant is profitable and feasible to be established.
