| dc.description.abstract | Acetic Acid Plant ofacetaldehyde and the air is designed with a capacity of 15,000
Ions / year and is planned to operate continuouslyfounded in Saht, Central Java with
an area of 26,000 m² and is designed to workfor 330 days ayear and 24 hours per
day. Background ofthe establishment ofthis factory is to meet the needs of Acetic
Acid in Indonesia. Preparation of Acetic acid using acetaldehyde oxidation process,
through several stages ofthe process as follows: raw material acetaldehyde and air
hubbies berkatalis reacted in a reactor ata temperature of 65ºC Manganese Acetate
pressure of 10 atm with 90% conversion. Products of the gas phase reactor will be
separated by water in the scrubber at atemperature of 65ºC and pressure of 10 atm
and in the recycle to the reactors. Products under the reactor were poured into the
distillation tower Ito purify the acetic acid. The yield on distillation menaara 1in the
recycle to the reactor and flowed to the bottom of the distillation tower 11 to obtain
acetic acid purity of 99.8% and 0.2% water. Acetic Acid plant utilities to include
water make-up of49,769,2X29 kg/h is takmfrom the Bengawcm Soh river, 542 kW
electricity, compressed air as much as 579.73 kg / hour, fuel as much as 29.3163 kg /
hour. Results ofeconomic analysis shows that these Acetic Acid plant requiresfixed
capital (Fixed Capital Investment) of U.S. $ 20,412,492.54 and working capital
(Working Capital Investment) ofU.S. $5,881535.92 with aprofd before tax of tip
40,774,904,173,32 and profit after tax ofRp. 20,287,452,086.66. The factory has a
Return on Investment fROl) before taxes and after taxes 19.98% 9.99%; Pay Out
Time (POT) before tax 3.46 years and after tax 5.56 years, Shut Down Point (SDP)
1139% and Break Even Point (BFP) 43,23%, with Discounted Cash Flaw Rate
(DCFR) 11,98%. Based on the above data, it can be concluded that Acetic Acidplant
is worth consideringfor its establishment. | en_US |
