Ferrous sulfate heptahydrate diproduksi dengan cara mereaksikan asam sulfat dengan pickling liquor pada suhu 85℃ tekanan 1 atm. Reaktor yang digunakan untuk mereaksikan bahan tersebut adalah Reaktor Alir Tangki Berpengaduk (RATB). Kapasitas produksi pabrik direncanakan sebesar 30.000 Ton/Tahun yang beroperasi selama 330 hari dalam setahun. Pabrik ini didirikan di Kota Cilegon, Provinsi Banten, tepatnya di Kawasan Industri Krakatau Industrial Estate Cilegon dengan luas tanah 25.218 m2. Bentuk perusahaan yang direncanakan adalah Perseroan Terbatas (PT) dengan menggunakan metode struktur organisasi garis dan staf (tenaga kerja sebanyak 146 orang). Sumber air pabrik ini berasal dari Sungai Cidanau, Kota Cilegon dengan total kebutuhan air sebesar 10.226,282 kg/jam, dan untuk kebutuhan listrik diperoleh dari Perusahaan Listrik Negara (PLN) dan generator dengan daya 1.834 kW. Hasil perhitungan analisis kelayakan ekonomi diperoleh Total Capital Investment (TCI) sebesar Rp. 365.788.486.930, Fixed Capital Investment (FCI) sebesar Rp. 310.920.213.890, Working Capital Investment (WCI) sebesar Rp. 54.868.273.039, Total Product Cost (TPC) sebesar Rp. 1.903.612.167.213, Sales sebesar Rp. 2.109.296.449.030, Laba Bersih sebesar Rp. 160.433.739.817, Return on Investment (ROI) sebesar 51,60%, Pay Out Time (POT) selama 1 tahun 5 bulan, Break Even Point (BEP) sebesar 38,71%, Shutdown Point (SDP) sebesar 26,99%, dan Internal Rate of Return (IRR) sebesar 28,22%.

Ferrous sulfate heptahydrate is produced by reacting sulfuric acid with pickling liquor at a temperature of 85°C and a pressure of 1 atm. The reactor used for this process is a Continuous Stirred Tank Reactor (CSTR). The planned production capacity of the plant is 30,000 tons per year, operating for 330 days annually. The plant will be established in Cilegon City, Banten Province, specifically in the Krakatau Industrial Estate Cilegon, with a total land area of 25,218 m². The proposed business entity is a Limited Liability Company (PT) using a line and staff organizational structure, with a total workforce of 146 employees. The plant's water supply will be sourced from the Cidanau River, Cilegon City, with a total water requirement of 10,226.282 kg/hour. Electricity needs will be met through the State Electricity Company (PLN) and a generator with a power capacity of 1,834 kW. Based on the results of the economic feasibility analysis, the Total Capital Investment (TCI) is IDR 365,788,486,930; Fixed Capital Investment (FCI) is IDR 310,920,213,890; Working Capital Investment (WCI) is IDR 54,868,273,039; Total Product Cost (TPC) is IDR 1,903,612,167,213; and Sales revenue is IDR 2,109,296,449,030. The Net Profit is IDR 160,433,739,817, with a Return on Investment (ROI) of 51.60%, a Pay Out Time (POT) of 1 year and 5 months, a Break Even Point (BEP) of 38.71%, a Shutdown Point (SDP) of 26.99%, and an Internal Rate of Return (IRR) of 28.22%.
