Prarancangan Pabrik Furfural Dari Biomassa Dengan Disain Alat Utama Reaktor Fluidized Bed
ABSTRACT
Furfural needs in the country is increasing along with the development of
industries such as paint industry, oil, pharmaceuticals, plastics and also polymer
industry. Indonesia's furfural needs to date still rely on imports from other
countries. Fufural is commonly produced using agricultural waste containing
pentosan, such as rice husks, corn cobs, wood, hemp, cane pulp, empty fruit
bunches and other sources containing fiber. Indonesia is a resource-rich country
that has the potential to produce raw materials for fufural production, one of
which is empty fruit bunches with a pentosan content of 25.90%. The amount of
waste of empty fruit bunches throughout Indonesia in 2004 has reached 18.2
million tons. The process of making furfural with Supra yield process takes place
in a solid-gas phase batch reactor, at a temperature of 206°C and a pressure of
18 atm where the hemicellulose in biomass is converted through 2 reaction
stages, hydrolysis and dehydration. The conversion process with a reaction time
of 15-20 minutes and using sulfuric acid catalysts as much as 3% of the feed
mass. The design result was obtained reactor with a height of 26.05 m and
diameter of 6.25 m and equipped with internal cyclone as separator between solid
particles attached to the gas product. The evaluation of the factory design
economic analysis shows that the factory is eligible to be established with the
factory's Return On Invesment (ROI) of 26.65%, the Break Event Point (BEP) is
35%, the Internal Rate of Return (IRR) is 22.74%, and the factory Payback Period
(PBP) is 2.75 years.
