Pra Rancangan Pabrik Asam Asetat dari Asetaldehid dan Udara Kapasitas Produksi 15.000 Ton/Tahun

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.
