This Biodiesel Plant will be established in Indramayu, West Java started
in this year with the capacity 8500 tons/year. Begin with the microalgae
cultivation process which is need at least 1 year to overcome the highly mass
production. We need 382.5 liter of microalgae to be cultivated in the beginning.
Total area needed is about 14.5 hectares, 90% of it is utilizing as cultivation area.
To produce biodiesel, we use reactive distillation technology through 2
steps of heterogeneous reaction, esterification and transesterification. The raw
materials are 39610.368 kg/hr of microalgae, 25936.86888 kg/hr of n-hexane as
the solvent in extraction process, and 3341.9232 kg/hr of methanol.
The utilities unit includes water at the rate of 56.0071 m
3
/ton of product
and electricity at the rate of 28.4737 kW/ton of product.
Based on economic analysis, the biodiesel plant has the following results:
1. Fixed Capital : Rp144,555,036,100.9
2. Working Capital : Rp27,770,748,480.07
3. Profit before taxes : Rp47,999,833,203.39
4. Profit after Taxes : Rp23,999,916,601.69
Feasibility Study Calculation Requirement
ROI after Taxes 16.60% 11% minimum
POT after Taxes 3.72 year 5 years maximum
BEP 42.78 % 40-60%
SDP 19.87%
DCFRR 30.88% 18% minimum
Based on the data above, the biodiesel plant from microalgae with
capacity 8500 ton/year is potential to be established
