Rancangan Pabrik Asam Nitrat Dari Ammonia Proses Ostwald Dengan Desain Alat Utama Absorber Nitrifikasi Reaktif (T-101)

ABSTRACT
Nitric acid (HNO₃) is a crucial industrial chemical widely used in various sectors, particularly as a raw material for producing ammonium nitrate fertilizers, explosives, and in the metal industry. The increasing demand for nitric acid in Indonesia each year is not aligned with the still limited domestic production capacity, causing Indonesia to rely on imports to meet national needs. This condition presents a significant opportunity for Indonesia to establish a nitric acid plant to enhance the self-sufficiency of the national chemical industry. The nitric acid plant is planned to be built in the Industrial Estate Area (KIE), Guntung Sub-district, North Bontang District, Bontang City, East Kalimantan, with a production capacity of 16,000 tons/year.
The nitric acid production process uses Ostwald technology, which offers advantages such as high conversion efficiency, short residence time, and high product purity. This process involves the stages of ammonia oxidation, nitrogen monoxide (NO) oxidation, and nitrogen dioxide (NO₂) absorption using a reactive nitrification absorber (T-101) specifically designed to produce nitric acid with 68% purity. The plant's electricity requirements are supplied by PLTG Bontang and a backup generator, with a total power requirement of 477.34 hp. The plant’s water demand of 132,735 kg/hour is met from the Guntung River and treated through an internal water treatment unit. The main liquid wastes originate from catalyst residues, laboratory waste, and domestic waste, with a total flow rate of 1,378 kg/hour. The process control system uses instruments such as sensors, indicators, controllers, recorders, and plant safety systems.
The results of the economic analysis show a Payback Period (PBP) of 3.525 years, an Internal Rate of Return (IRR) of 15,16%, a Break Even Point (BEP) of 38.61%, a Return on Investment (ROI) of 32.27%, and a Net Present Value (NPV) of IDR 642 billion. Based on the economic feasibility analysis, the nitric acid plant is deemed feasible to establish. Sensitivity analysis indicates that the IRR is most sensitive to changes in product price, while it is least sensitive to changes in raw material prices and Fixed Capital Investment (FCI).
Keywords: Nitric Acid, Ostwald, Reactive Nitrification Absorber, Economic Feasibility Analysis, Sensitivity.
