TITLE OF PRE DESIGN TASK:
PRE DESIGN FACTORY “LIGNOCELLULOSE FRACINATION FROM OPEFB USING STEAM EXPLOSION METHOD”

Supervisor :
Lignocellulosic biomass is a very promising raw material for making renewable fuels. This biomass is a substantial substrate for the production of bioethanol, a biochemical product whose availability and abundance is renewable and will not compete with food and animal feed. Lignocellulose mostly contains a mixture of carbohydrate polymers such as cellulose and hemicellulose as well as lignin. According to technavio.com, the market size of lignocellulosic feedstock based biofuels has the potential to grow by USD 7.83 billion during 2020-2024, and the market growth momentum will pick up during the forecast period.
Based on cellulose supply and demand data, Indonesia exports a lot of cellulose from other countries to meet industrial needs in Indonesia. Meanwhile, cellulose, hemicellulose and lignin can be produced from coconut fiber. Indonesia’s coconut production potential reaches 15 billion coconuts per year so that Indonesia is able to produce coconut coir of around 1.875 million tons per year. Availability of coconut coir which is quite a lot at this time has not been utilized as much as possible. With a fairly high market demand both from abroad and domestically, Indonesia needs to build a biomass processing industry from coconut fiber.
Therefore, the lignocellulosic fractionation plant from coconut fiber was established with the aim of helping this problem, where this plant will be operated in batches with 3 running times for 24 hours in 330 days per year and a production capacity of 699.4511 tons/year. From this capacity, coconut coir raw materials are needed at 1650 tons/year, NaOH solution as much as 315,150 tons/year, H2SO4 solution as much as 539,550 tons/year, requires power of 228,349 Hp and requires heat of 12,593,653,234 kJ. This factory will be established on Jalan Raya Ringar Timur Buduran Sidoarjo with a land and building area of 14000 m2.
The establishment of this factory is scheduled to start in 2022 and be completed in 2024. Where the lignocellulosic fractionation process consists of 3 processes, namely the pretreatment process (steam explosion method), the delignification process and the precipitation process.
From the calculation of the economic analysis, the rate of return on capital (IRR) of this factory is 30.81% with a bank interest rate of 9.95% per year. Meanwhile, the payback period (POT) is 3 years 5 months and the break-even point (BEP) is 19%. To set up a lignocellulosic fractionation plant from coconut coir, a total annual production cost of Rp. 52,527,818,883.6 with a total investment cost (TCI) of Rp. 132,231,158,918. If considered from the aspect of economic and technical analysis, this lignocellulosic fractionation plant from coconut fiber using the steam explosion method is feasible.
