Education
Pre-design Plant of Ethanol by Acetic Acid and Hydrogenation Process with Capacity 90,000 Ton/Year Ethanol with the molecular formula C2H5OH is a chemical compound that is colorless, volatile and has a distinctive odor which is used in the paint industry, alcoholic beverages, cosmetic products, chemical raw materials, food industry and pharmaceutical and medical industries. The design of an ethanol plant with a capacity of 90,000 tons/year is located in an industrial area taking into account the distance to raw materials and transportation. Ethanol is formed from the hydrogenation of acetic acid and hydrogen using SiO2-Al2O3 supported Pt-Sn as a catalyst. The raw materials in this design consist of acetic acid and hydrogen. The reaction takes place exothermically in a fixed bed multitube reactor with a temperature of 300°C and a pressure of 17 atm and produces a by-product in the form of ethyl acetate. The separation process in this factory consists of 4 distillation tower units and 1 absorber unit. In the distillation tower a DMSO entrainer is used to separate the ethanol - ethyl acetate azeotrope components. The utility system at this factory uses water from PT Krakatau Tirta Industri with a demand of up to 1,186.37 tonnes/hour, diesel fuel of 0.3 tonnes/hour and air requirements of up to 0.06 tonnes/hour. The electricity required by the factory for processing, utility and other support needs is 7,873.43 KWh. Based on the calculated economic review, the return on investment was 37.57%, the break even point was 41.57%, the shut down point was 24.81%.
