Pra Rancangan Pabrik Sikloheksana dari Benzena dan Hidrogen dengan Proses Hidrogenasi Menggunakan Katalis Paladium Kapasitas 140.000 Ton/Tahun

Abstract

Pre-design of the cyclohexane production plant from benzene and hydrogen through a hydrogenation process has a production capacity of 140.000 tons per year and operates for 330 days per year. The main process in this plant's preliminary design consists of three stages: raw material preparation, benzene hydrogenation, and product separation and purification. The amount of benzene required to reach the annual production capacity is 17.331.386 kg/hour. This cyclohexane production plant, utilizing a hydrogenation process from benzene and hydrogen, is planned to be established in the Krakatau Steel Industrial Area, Cilegon, West Java, with a total plant area of 21.061 m². The water requirements for the plant will be supplied by PT Krakatau Tirta Industri at a rate of 367.803.873 kg/hour. The planned company organization form is a Limited Liability Company (PT) with a line and staff organizational structure, employing a total of 99 peoples. The economic evaluation shows an investment capital (CI) of IDR 697.349.494.906, total production costs of IDR 2.899.774.328.505, and sales of IDR 3.505.756.090.994, with a net profit of IDR 456.281.267.073. The profit margin is 37,35%, ROI is 32,58%, and IRR is 52,2%. The project is projected to break even (BEP) at 36,1% of the capacity, with an investment payback period (POT) of 2 years and 2 months. Based on the economic analysis, the preliminary design of this plant is considered feasible for realization.
