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

Abstract

Acetic Acid Plant of acetaldehyde and the air is designed with a capacity of 15,000 tons/year and is planned to operate continuously founded in Saht, Central Java with an area of 26,000 m² and is designed to work for 330 days a year and 24 hours per day. Background of the establishment of this factory is to meet the needs of Acetic Acid in Indonesia. Preparation of Acetic acid using a cetaldehyde oxidation process, through several stages of the process as follows: raw material a cetaldehyde and air hubbies berkatalis reacted in a reactor at a temperature of 65ºC Manganese Acetate pressure of 10 atm with 90% conversion. Products of the gas phase reactor will be separatedby water in the scrubber at a temperature of 65ºC and pressure of 10 atm and in the recycle to the reactors. Products under the reactor were poured into the distillation tower I to purify the acetic acid. The yield on distillation menaara I in 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 of 49,769,2X29 kg/h is taken from the Bengawan Solo river, 542 kW electricity, compressed air as much as 579.73 kg/hour, fuel as much as 29.3163 kg/hour. Results of economic analysis shows that these Acetic Acid plant requires fixed capital (Fixed Capital Investment) of U.S. $ 20,412,492.54 and working capital (Working Capital Investment) of U.S. $5,881535.92 with aprofd before tax of tip 40,774,904,173,32 and profit after tax of Rp. 20,287,452,086.66. The factory has a Return on Investment (ROI) 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.
