Prarancangan pabrik natrium nitrat menggunakan bahan baku berupa asam nitrat dan natrium hidroksida. Proses produksi secara keseluruhan menggunakan proses netralisasi, pemekatan menggunakan multiple effect evaporator dan cooling crystallization. Kapasitas produksi sebesar 55.000 ton/tahun dengan waktu operasi 330 hari/tahun dan waktu 24 jam/hari. Pabrik ini direncanakan dibangun di Kepuh, Kecamatan Ciwandan, Kota Cilegon, Banten, Indonesia. dengan luas area pabrik 10.000 m2. Bentuk perusahaan yang direncanakan adalah Perseroan Terbatas (PT) dengan menggunakan metode struktur organisasi garis dan staf dan tenaga kerja sebanyak 149 orang. Kebutuhan air untuk pabrik berasal dari Sungai Cidanau dengan laju alir 72.426,558 kg/jam, dan untuk kebutuhan listrik diperoleh dari generator dengan daya 1.759,574 kW. Hasil analisis ekonomi diperoleh sebagai berikut:
1. Fixed Capital Investment (FCI) = Rp 1.287.041.007.123,15
2. Working Capital Investment (WCI) = Rp 280.508.937.449,92
3. Total Capital Investment (TCI) = Rp 2.805.089.374.499,17
4. Total Production Cost (TPC) = Rp 6.433.722.821.246,65
5. Sales Cost (SC) = Rp 8.150.490.785.172,15
6. Laba Bersih = Rp 1.287.575.972.944,13
7. Pay Out Time (POT) = 3,41 tahun
8. Break Event Point (BEP) = 38,48 %
9. Internal Rate of Return (IRR) = 15,59 %
10. Rate of Return (ROR) = 45,90 %
Berdasarkan studi kelayakan teknis dan ekonomis diatas, maka dapat disimpulkan bahwa Prarancangan Pabrik Natrium Nitrat ini layak untuk dilanjutkan ke tahap rancangan.

Sodium Nitrate Plant Design uses raw materials in the form of Nitric Acid and Sodium Hydroxide. The overall production process uses a neutralization process, concentrating using multiple effect evaporators and cooling crystallization. The production capacity is 55,000 tons/year with an operating time of 330 days / year and 24 hours / day. This factory is planned to be built in Kepuh, District Ciwandan, Cilegon City, Banten, Indonesia,with a factory area of 10.000 m2. The company form planned is a Limited Liability Company (PT) using the line and staff organization structure method and a workforce of line and staff organization and a workforce of 149 people. Water needs for the plant come from the Cidanau River with a flow rate of 72.426,558 kg / hour, and for electricity needs obtained from a generator with a power of 1.759,574 kW. The results of the economic analysis are as follows: 1. Fixed Capital Investment (FCI) = Rp 1.287.041.007.123,15 2. Working Capital Investment (WCI) = Rp 280.508.937.449,92 3. Total Capital Investment (TCI) = Rp 2.805.089.374.499,17 4. Total Production Cost (TPC) = Rp 6.433.722.821.246,65 5. Sales Cost (SC) = Rp 8.150.490.785.172,15 6. Laba Bersih = Rp 1.287.575.972.944,13 7. Pay Out Time (POT) = 3,41 tahun 8. Break Event Point (BEP) = 38,48 % 9. Internal Rate of Return (IRR) = 15,59 % 10. Rate of Return (ROR) = 45,90 % Based on the technical and economic feasibility studies above, it can be concluded that the Preliminary Plant Design of Sodium Nitrate is feasible to proceed to the design stage.
