Pra Rancangan Pabrik Pembuatan 2-Phenylethanol dari Benzena dan Oksirana melalui Proses Alkilasi Friedel Crafts dengan Penambahan Unit Pemisah Knock Out Drum Kapasitas Produksi 13.000 Ton/Tahun

Abstract

2-Phenylethanol (2-PE) is a higher aromatic alcohol product with a scent/taste identical to that of flowers and is one of the most important fragrance chemicals in the perfume, cosmetics, and other chemical industries. The need for the use of 2-Phenylethanol in Indonesia in the chemical industry is increasing every year. Therefore, it is planned to establish a 2-Phenylethanol manufacturing plant using benzene and oxyrane raw materials. In the preliminary design, the 2- Phenylethanol production facility utilizing Benzene and Oxyrana has a production capacity of 13,000 tons/year and operates for 330 days annually. The primary process in the preliminary design of this facility comprises four stages: raw material preparation, reaction, benzene recovery, and final product purification. The reaction involves a Friedel-Crafts alkylation that occurs in three continuous stirred tank reactors arranged in series, operating at a temperature of 9°C and a pressure of 0.855 atm, with a residence time of 40 minutes for each reactor. The proposed factory is to be established in the Suryacipta Industrial Estate, located in Karawang Regency, West Java Province, encompassing an area of 17,926 m2. The facility will require a workforce of 195 individuals and will operate as a Limited Liability Company (PT) under the leadership of a President Director. The establishment and operation of the factory necessitate an investment capital of IDR 2,814,532,505,209 and entail production costs of IDR 2,579,598,768,918. Based on the feasibility analysis, this plant exhibits a Break-Even Point (BEP) of 47.957%, a Return on Investment (ROI) of 17.254%, a Payback Period (POT) of 5 years and 10 months, a Return on Net worth (RON) of 28.757%, and an Internal Rate of Return (IRR) of 19.32%. The results of the economic analysis indicate that the pre-design of a facility for the production of 2-Phenylethanol from benzene and oxyrane utilizing the Friedel-Crafts alkylation process is economically viable.
