| Summary: | The BioJet A-1 production line from microalgae oil and methanol begins
with the extraction of microalgae oil from microalgae using n-hexane. This
process is followed by Esterification at a temperature of 100 ° C and a pressure of
6 atm. After that the oil goes through Trans-esterification process at a
temperature of 60 ° C and a pressure of 1 atm. The result of this process is then
heated to purify Methyl Ester and followed by Hydrodeoxygenation at a
temperature of 500oC and a pressure of 1 atm. This process aims to transform the
Methyl Esters to Hydrocarbons that is similiar jet fuel specification (Jet A-1). The
heat of Hydrodeoxygenation product is used to heat the boiler and then it goes to
Fractination Column where the BioJet A-1 product is purified.
BioJet A-1 plant will be built at Tulang Bawang, Lampung with land area
of 21 hectares and employees of 81 people. The plant uses 281.228 kg/h
microalgae as raw materials, methanol 6883.17 kg/h and hydrogen 2569.42 kg/h.
The need for 971,746.3 kg/h water utilities is obtained from Tulang Bawang
River, Lampung. The other needs of the plant are electricity demand of 1382.54
kW, fuel demand of 1173.39 kg/h and instrument air requirement of 180 m3/hr
(STP).
Based on economic analysis, BioJet A-1 plant needs a Fixed Capital of Rp
2,186,377,167,775.27 and a Working Capital of Rp 876,424,429,216.52. The
plant will have profit before taxes of Rp 547,150,175,019.75 and after taxes of Rp
273,575,087,509.88. Rate of Investment (ROI) before taxes amounted to 25.03%
and after tax of 12.51%. Pay Out Time (POT) before taxes of 2.86 years and after
taxes of 4.44 years. Break Even Point (BEP) Value and Shut Down Point (SDP)
Value are 51.10% and 23.75%, respectively. Meanwhile DCFRR of the plant is
14.21%.
Based on the evaluation above, the BioJet A-1 plant from microalgae with
a capacity 200,000 tons/year is feasible for further consideration. |
