| dc.description.abstract | The pre-designed factory for the production of bio-char from empty palm
oil bunches using a slow pyrolysis process has a production capacity of 80,000
tons/year on a calculation basis of 1 hour of operation, 330 working days for 1
year. There are three processes in the manufacture of bio-char namely pyrolysis,
hydrothermal carbonization and gasification. This bio-char manufacturing plant
uses slow pyrolysis because it produces a high yield.
The specific task that was completed was the detailed engineering design
of the fluidized bed reactor. The designed reactor has the following specifications:
• Material of Construction : Stainless Steel SA-240, Grade A
• Type : Fluidized Bed
• Tank volume : 4,838 m3
• Tank diameter : 1,665 m
• Tank height : 1,665 m
• Plate thickness : 0,308 in
• Plate jacket : 0,243 in
The bio-char manufacturing plant from empty palm oil bunches is planned
to be established in Rokan Hilir Regency, Riau Province, with the required land
area of 16,440 m2, the form of a Limited Liability Company (PT) business entity
led by a main director with a line system organizational structure and staff with
The number of workers is 212 people.
The results of the economic analysis of the bio-char manufacturing plant
from empty palm oil bunches with this slow pyrolysis process are as follows:
1. Investment Capital : Rp 539.858.074.746,-
2. Production Cost : Rp 778.019.060.955,-
3. Net Profit : Rp 370.087.557.032,-
4. Profit Margin (PM) : 40,137%
5. Break Even Point (BEP) : 24,698%
6. Return on Investment (ROI) : 68,533%
7. Pay Out Time (POT) : 1,458 tahun
8. Return on Network (RON) : 84,273%
9. Internal Rate of Return (IRR) : 78,767%
From the results of the analysis, it was found that a factory for making biochar
from empty palm oil bunches with a slow pyrolysis process is feasible to
build. | en_US |
