Pra Rancangan Pabrik Ethanol Dari Ethylene Dan Air Kapasitas 45.000 Ton/Tahun

Abstract

Preliminary design of Ethanol with capacity 45.000 ton/year is plant be built in industry area Tangerang-Banten, in the area of land 30,000 m2 This chemical plant will be operated for 330 day/year or 24 hours aday with 167 employees Raw material neededs is Ethylene 4.943,29 kg/hour, Water 8,005 333 kg/hour. The production process will be operated at temperature 25C> C,at pressure about of 68 atm using Fixed Bed Multitube with convesion23/o . The utiliy consist of 115,4992.4552 kg/hour of cooling water, 2.216 94t^hour of processing water, 2041.6667 kg/hour ofhousing water, 241,838.5891 kg/hour of steam 3615.081 mVhour of fuel while the power of electricity oj about 15.915.128 kwh provided by PLN. This chemical plant also use generator set as ' An economic analysis shows thats this chemical plant need to be covered by fixed capital of about Rp.369,203,179,395.53, working capital of about Rp 226 027 125 785.75. The profit before tax is Rp.79,505,888,323.88 while the profit after tax is Rp.39,752,944,161.94. Percentage of return on investemen (ROI) before tax is 21,53% while after tax is 11,77%. Pay out time (POT) before tax is 317 years while after tax is 4,82 years, Discounted cashflow rate (DLbR) for about 23 99% The value ofbreak evekpoint (BEP) for about 52,74% and shut down point (SDP) of about 21,04%. Based on the economic analysis, It is concluded that plant design of Ethanol with capacity 45,000 ton/years visible to be built.
