| Summary: | Preliminary design of this ethyl formate plant is intended to asses the
feasibility of this plant. Ethyl formate plant is designed to fulfill 60.000 ton/year of
capacity and to be operated continuously 330 days/year. In order to gain the ethyl
formate product as designed capacity, 40043,53 ton/year of ethanol 95% (w/w)
and 40793,78 ton/year of formic acid 94% (w/w) are required as main raw
materials.
The sysntesis of ethyl formate is based on the esterification process and
catalyzed by sulphuric acid. The reaction takes place in a reactive distillation
column in atmospheric condition. Another distillation column is needed to further
purify the ethyl formate product up to 98,6% (w/w) of concentration.
To be constructed in Cilegon, Banten, this plant requires 12.000 m2 area
and employs 216 labors. The consumed energy includes electricity of 1594607,09
kWh/year and 25604,08 m3/year of fuel oil. Moreover, the utility requires
26040,00 kg/hour of make-up water and 150 m3/hour of air instrument.
Fixed capital costs $ 14,534,181.82 + Rp 88.444.256.897,33 and working
capital costs $ 12,993,533.03 + Rp 239.401.583.121,16. Based on the economical
feasibility study, this plant is classified as low risk chemical plant with 43,38% of
ROI (before taxes)
