Pra-Rancangan Pabrik Anilin dengan Hidrogenasi Nitrobenzen Fase Uap Kapasitas 40.000 Ton/Tahun

Abstract

Aniline prepared by reacting hydrogen with nitrobenzen at a temperature of 270 ° C and pressure of 2.3 atm in a fluidized bed reactor at isothermal conditions. Nitrobenzen mole ratio: moles of hydrogen is 1: 6. reaction that occurs is exothermic, so as to maintain the temperature of the reactor flow used cooling in the coil. Coolant used is DOWTHERM A. Aniline plant was designed with a capacity of 40,000 tons / year. The raw material required is nitrobenzen 99.8% as much weight tons / year and as much pure hydrogen ton / year. The resulting product of aniline with a purity of 99.94% with the impurity of benzene, water and nitrobenzen. The factory location is planned in Cilegon, Banten and built on land with an area of 20,000 m2. plant operates 24 hours and 330 days per year. The amount of labor as much as 180 people. Existing process equipment such as a vaporizer, separator, pump, fluidized bed reactors, distillation towers, and heat exchanger. Support unit was established to support the production process consisting of units of water, steam, electricity, fuel supply, and sewage treatment units. That the quality of raw material and product quality under control, then the existence of the laboratory is needed. The results of the economic analysis of the obtained aniline plant that total capital investment (TCI) of Rp. 517 833 815 122, - and the total cost of production (Production Cost) Rp. 1 068 132 870 317, -. Feasibility analysis of the results obtained from the ROI before taxes 52.20% and 39.15% after tax. POT before tax and after tax 1.6 years 2 years, BEP 53.12%, SDP 41.01% and DCF of 29.52%. On economic analysis has been done, it can be concluded that the establishment of aniline plant with a capacity of 40,000 tons / year can be considered for development is realized.
