Prarancangan Pabrik Vinil Asetat dari Etilen, Asam Asetat, dan Oksigen dengan Kapasitas 30.000 Ton/Tahun

Abstract

The requirement of vinyl acetat know by sight increase along with the increase of chemical industry in Indonesia. Vinyl acetat is used as monomer for the production of polyvinyl acetat, vinyl acetat copolymer, vinyl chloride and polyvinyl alcohol process that is used as raw material in the plastic industry, be sides that vinyl acetat also is used as aditif industry in the lubricant oil and as raw material in the paint industry, film paper, and ink. Vinyl acetat factory is designed with 30.000 ton/year of capacity with the raw material 99,9 % of etilen, pure oxygen and 99,5 % of acid acetat. The factory is designed and will be established in the Cilegon, Banten, because the tools have been available. Reactor that is used is fixed bed multitube, with the condition of operation: 170 o C temperature and 8 atm of pressure with Palladium catalisator. Reaction taken place of gas phase and eksothermis. The process of making vinyl acetat taking place in 3 three stage are : preparing of raw material stage, reaction stage, separation and purification of product stage. The utility required are 11726,4703 Kg/hour of water supply, 13.670,9914 Kg/hour of steam, 553 Kwh of electricity supply, and The fuel that is used for bringing into play the generator is 609.106.815.711 ltr/year, whe are as for boiler is 11.966.572,1980 ltr/year. An economic analysis showed this plant will have that percentage of 37,39 % of rate after taxes on Investment (ROI), 2,67 years of Pay Out Time after taxes (POT), 13,98% of Discounted Cash Flow Rate (DCFR), 43,21 % of Break Event Point (BEP), 29,55 % of Shut Down Point (SDP). From the analyses above it showed that the result was satisfied so the plant are interesting and appropriate to build.
