Abstract
Commercially produced and marketed Ammonium Nitrate is available in crystalline form with a purity of more than 99%. Ammonium Nitrate is widely used in industry as a raw material for nitrogen fertilizers, a raw material in the production of industrial explosives, and as a component in instant cold packs or disposable cooling packs. Currently, Indonesia still imports Ammonium Nitrate from other countries to meet domestic demand. Therefore, the establishment of an Ammonium Nitrate plant is one of the efforts to fulfill domestic demand for raw materials in other industries, which is expected to increase over time. In the production of Ammonium Nitrate, this plant employs the Vacuum Crystallization process using Ammonia and Nitric Acid as raw materials. The Nitric Acid feed is contacted with Ammonia gas in a stirred bubble reactor at 60°C and 4 atm. Under these conditions, the reaction conversion can reach 90.08%, after which the resulting Ammonium Nitrate crystals undergo a purification process, followed by drying and packaging. The proposed Ammonium Nitrate plant has a production capacity of 65,000 tons/year and will be located in the Kawasan Industri Estate (KIE), Bontang, East Kalimantan. The plant will operate 24 hours per day for 330 days per year. The results of the economic analysis of the proposed Ammonium Nitrate plant are as follows: a. Total Capital Investment (TCI) : IDR 775,817,174,379 b. Total Production Cost (TPC) : IDR 1,015,118,114,679 c. Return on Investment (Before Tax) : 27.93% d. Return on Investment (After Tax) : 20.95% e. Internal Rate of Return (IRR) : 16.56% f. Payback Period (PBP) : 3 years 8.5 months g. Break-Even Point (BEP) : 38.94%
