Prarancangan Pabrik Etilbenzen dengan Proses Unocal/UOP dari Etilen dan Benzen Kapasitas 250.000 Ton/Tahun

摘要

The chemical industry continues to developing in spread and integrated.This is the catalyst construction of industrial units.Ethylbenzene needs both in foreign or the current increases 2.9 percent every year.The establishment of ethylbenzene factory in indonesia is the first step to creating a climate that mutually beneficial, because ethylbenzene is the raw material of the manufacture of monomers styrene used as raw materials for making plastics synthetic.ududUnocal / unit oil product ( uop is the process of most newly developed .The process is using the system recovery catalyst for the environment safe .The process transalkylationand alkylation place on the gas in one fixed bedmultitubereactor on the condition of the operation of 150-200oC and pressure 5 atm .The production of ethylbenzeneas many as 31.565,6565 kg per hour needed raw materials as much as benzene 23.228,8681 kg per hour and ethylene as many as 8.371,1065 kg per hour .Utility include the provision of water the process of 324.211,24 kg per hour , water for cooling in the process of 235.078,33 kg per hour , water to the needs of a steam of 44.961,13 kg per hour produced from the boiler , water for sanitation of 2.092,44 kg per hour .Electricity needs by 458,85 kw obtained from nel and provided a generator set as a reserve .The needs of compressed air of 50,00 cubic meters per hour .This factory planned area established in this industry , banten in the year 2024 with a broad land 45,000 meters and requires employees 122 people.ududFactory of Ethylbenzene using fixed capital as much as Rp684.839.603.900,00and working capital as much as Rp418.350.900.465,00.From the economic analysis of this plant showed a profit before tax of Rp Rp319.638.091.771,00per year and after taxes 30% profit reachedRp Rp223.746.664.240,00per year. Percent Return On Investment (ROI) before tax 46.67% and 32.67 % after tax. Pay Out Time (POT) before tax 1.76 years and after tax 2.34 years. Break Even Point (BEP) of 58.75%, and Shut Down Point (SDP) of 46.37%. Discounted Cash Flow (DCF) as much as 54%. From the data above feasibility analysis concluded that the plant is profitable and feasible to set up.
