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
