| dc.description.abstract | Furfural is organic chemical material that most commonly consume as
solvent in several industries. Furfural has chemical formula C5H4O2 dan more
recognize as furfuraldehid or furfural, sometimes it called with fural. Furfural is
furan aldehid with CHO group in second position. Furfural is a liquid that has
boiling point 161,7°C and molecular weight 96,08. Sulfuric acid ( H2S04 ) is use to
get furfural from corn cobs as catalyst. Corn cobs has a relatively high pentosan
content are hydrolyzed to pentoses, which, in turn, split out water toform furfural.
This reaction has operate in five batch revolving tanks with pressure 3,09 atm and
temperature 137 °C. Ratio ofcorn cobs and water is3 : 1.
This plant is design with capacity 60.000 tons/year. The needed of raw
material 52744,0084 kg/hour of corn cobs, 7753,3693 kg/hour of sulfuric acid,
13186,0021 kg/hour of water and 140650,1950 kg/hour ofsteam. This plant works 24
hours/day andoperatefor 330 days/year. This plant will be built in Gresik, East Java
with labours manyas 168people.
