Pabrik Biodiesel dari Minyak Kelapa dan Metanol dengan Kapasitas 25.000 Ton/Tahun

Abstract

Preliminary design of Fatty Acid Methyl Ester with capacity 25.000 ton/year is planned to be built in Indragiri Hilir, Riau in the area of 27.875 m2 . This chemical plant will be operated for 330 day/year or 24 hours a day with 138 employees. Coconut oil as the main raw material flows at rate 1022,983 kg/hour, methanol 2785,997 kg/hour, Sulfuric Acid 6,965 kg/hour and Kalium Hidroxide 20,895 kg/hour. The production process will be operated for esterification and transesterification at temperature 60 ̊C, at pressure 1 atm using Continuous Stirred Tank Reactor (CSTR) with convertion reaction 98%. The utiliy consist of 193.165,85 kg/hour of cooling water; 13.882,992 kg/hour of steam;1.319.710,7214 Lt/hour of fuel oil while the power of electricity of about 116,2623 Kwh provided by PLN. Studies on the economic evaluation of this plant has led to conclusion that it needs fixed capital of Rp 686.981.068.012,24; working capital of Rp 210.117.738.849,16. The profit before tax is Rp 168.329.446.964,45 while the profit after tax is Rp 100.997.668.178,67. Percentage of return on investement (ROI) before tax is 24,50% while after tax is 14,70%. Pay out time (POT) before tax is 2,90 years while after tax is 4 years. shut down point (SDP) is 16,41% with Discounted Cash Flow Rate (DCFR) is 18,5%.Based on the economic analysis, It is concluded that plant design of Fatty Acid Methyl Ester with capacity 30.000 ton/years visible to be built.
