| dc.description.abstract | Pre-design of sodium lignosulfonate manufacturing plant from coconut fiber
using a delignification process of organosolv it has a capacity of 20,000 tons/year and
operates 330 days a year. The main process in this pre-design consists of four stages,
which is, the raw material preparation stage, the delignification stage, the lignin
isolation stage, and the sulfonation stage. At the delignification stage, a process is
applied organosolv by using an organic solvent in the form of methanol as a cooking
solution. Meanwhile, in the sulfonation stage, the operation is carried out at a
temperature of 90°C for 1 hour. The amount of coconut fiber required to reach annual
production capacity is 6,259.2368 kg/hour.
The factory for making sodium lignosulfonate surfactant from coconut fiber is
planned to be established in Rokan Hilir Regency, Riau Province, with a total area of
22,545 m2. The planned form of company organization is a Limited Liability Company
(PT) with a total of 179 employees.
The results of the economic analysis of this pre-design are as follows:
1. Capital Investment (CI) = Rp983.278.131.893
2. Total Cost (TC) = Rp692.024.984.476
3. Profit Margin (PM) = 23,35%
4. Break Even Point (BEP) = 37,74%
5. Return on Investment (ROI) = 15,26%
6. Return on Network (RON) = 35,43%
7. Pay Out Time (POT) = 6 year 7 month
8. Internal Rate of Return (IRR) = 14,289%
Based on economic analysis, it can be concluded that the design of a sodium
lignosulfonate surfactant factory from coconut fiber using a delignification process
oraganosolv this is worth establishing. | en_US |
