| dc.description.abstract | The preliminary plant design of the ethyl acetate manufacturing plant from
ethanol and acetic acid using esterification process has a production capacity of
142.000 tons/year and operates for 330 days of operation per annum. The main
process in the pre-design of this factory consists of three stages, namely the stage
of the raw material preparation, the stage of formation of ethyl acetate
(esterification process), and the stage of separation and purification of ethyl acetate.
The reaction is a reaction of ethanol and acetic acid with homogeneous catalyst of
sulfuric acid which takes place in a continuous stirred tank reactor under
temperature conditions of 80oC for 0,612 hours. The amount of acetic acid needed
to reach the annual production capacity is 18.535,644 kg/hour.
The specific task was solved for the detail engineering design of the
continuous stirred tank reactor for esterification reaction. Continuous stirred tank
reactor that has been designed has the following specifications:
• Diameter of the reactor : 3,085 m
• Height of the reactor shell : 3,085 m
• Height of the reactor head : 0,618 m
• Total height of the reactor : 4,321 m
• Thickness of the reactor shell : 3
8 ⁄ in
• Thicness of the reactor head : 3
8 ⁄ in
• Stirred type : Turbin datar berdaun enam
• Material of the reactor : Stainless steel SA-240 type 316
Ethyl acetate manufacturing plant from ethanol and acetic acid using
esterification process is planned to be established in Ngelom I, Sroyo, Kecamatan
Jaten, Kabupaten Karanganyar, Provinsi Jawa Tengah, with the total area of the
plant area are 14.179,200 m3. The water needs at this plant are supplied from the
Begawan Solo River as much as 9.539,843 kg/hour. The planned form of corporate
organization is Perseroan terbatas (PT) with a line and staff organization structure,
as well as a total of 160 employees.
The economic analysis results on this preliminary plant design are as follows:
• Capital Investment (CI) = Rp 2.759.280.884.127
• Total Cost (TC) = Rp 2.045.461.875.666
• Profit Margin (PM) = 27,939%
• Break Even Point (BEP) = 32,883%
• Return On Investment (ROI) = 20,160%
• Pay Out Time (POT) = 4 years 10 months
• Return On Network (RON) = 33,601%
• Internal Rate of Return (IRR) = 20,064%
Based on the results of economic analysis, it can be concluded that the ethyl
acetate manufacturing plant from ethanol and acetic acid using esterification
process is feasible to be established. | en_US |
