Pra Rancangan Pabrik Ethanolamine dari Ethylene Oxide dan Ammonia Kapasitas 25.000 Ton/Tahun

Abstract

Preliminary design of monoethanolamine using raw matrial of ethylene oxide and ammonia with annual capacities of 25,000 ton is planned to be founded in industrial area of Bontang, East Kalimantan, about land for the width of 30,000 m², requiring labours amount of 100 people, planned on 2010. Reactions in continous stirred tank reactor, with conditions 2.5 aim and 50 °C. Raw material of ethylene oxide 5980.16226 Kg/hour and ammonia 9452.93126 Kg/hour. To support process needed by water counted 352652.1128 Kg/hour, electric power 304.5865 KW. Economic analisys show that chemical plant need to convered by fixed capital ofabout Rp 323.576.332.288 , working capital ofabout Rp. 183.572.185.088 and total product cost of about Rp 504.469.913.600. The profit before tax is Rp 215.667.113.984 while after tax is Rp 107.833.556.992. Percent return of investment (ROI) before and after tax are 66.651 %and 33.32554 %, for the Pay Out Time (POT) before tax is 1.304years andafter tax is 2.308years. Break Even Point (BEP) 40.98 %capacity, Shut Down Point (SDP) 13.48 %and Discounted Cash Flow of Return (DCFR) is 47.09977 %. From an economic evaluation result, it can be concluded that Monoethanolamineplant is visible and excite to built.
