Abstract

The research presents a water optimization initiative implemented at PT Petro Jordan Abadi’s phosphoric acid facility, which operates using the hemihydrate–dihydrate (HDH) Nissan-C process. The study was motivated by the high freshwater dependency of the phosphoric acid production system and the increasing need for sustainable resource management in chemical process industries. A comprehensive evaluation of internal water flows was undertaken to identify opportunities for reduction, substitution, and reuse that align with circular economy and industrial symbiosis principles. A detailed water balance model was developed to analyze the plant’s water consumption patterns and quantify the potential for internal recycling. Based on this assessment, a circular water reuse network was designed, whereby cooling tower blowdown from the sulfuric acid (SA) plant is repurposed as makeup water in the phosphoric acid (PA) plant. This configuration transforms a previously wasted effluent into a valuable input stream without compromising process performance, providing a practical and cost-effective pathway for water conservation within the integrated plant. Implementation of the redesigned water system resulted in significant efficiency gains. Freshwater consumption was reduced by approximately 17%, decreasing from about 5.3 to 4.4 m³ per metric ton of P₂O₅ produced, equivalent to roughly 630 m³ of water saved per day. These outcomes demonstrate the feasibility and effectiveness of internalwater recycling in phosphoric acid production and highlight the broader potential for circular resource strategies in the chemical process industry. Keywords: Circular economy; HDH Nissan-C process; Industrial sustainability; Water balance modeling; Water optimization.

Penelitian ini memperkenalkan sebuah inisiatif optimasi penggunaan air yang diterapkan di fasilitas produksi asam fosfat PT Petro Jordan Abadi, yang beroperasi dengan proses hemihidrat–dihidrat (HDH) Nissan-C. Studi ini dilatarbelakangi oleh tingginya ketergantungan proses produksi asam fosfat terhadap air segar serta meningkatnya kebutuhan pengelolaan sumber daya yang berkelanjutan di industri roses kimia. Evaluasi menyeluruh terhadap aliran air internal dilakukan untuk mengidentifikasi peluang pengurangan, substitusi, dan pemanfaatan kembali yang sejalan dengan prinsip ekonomi sirkular dan simbiosis industri. Model neraca air yang terperinci dikembangkan untuk menganalisis pola konsumsi air di pabrik dan menghitung potensi daur ulang internal. Berdasarkan analisis tersebut, jaringan pemanfaatan kembali air secara sirkular dirancang, di mana blowdown cooling tower dari pabrik asam sulfat (SA) dimanfaatkan sebagai make-up water pada pabrik asam fosfat (PA). Konfigurasi ini mengubah aliran limbah yang sebelumnya terbuang menjadi sumber daya yang bernilai tanpa mengurangi kinerja proses, sehingga memberikan solusi konservasi air yang praktis dan ekonomis dalam sistem pabrik terintegrasi. Implementasi sistem air yang telah didesain ulang menghasilkan peningkatan efisiensi yang signifikan. Konsumsi air segar berhasil dikurangi sekitar 17%, dari sekitar 5,3 menjadi 4,4 m³ per ton P₂O₅ yang diproduksi, yang setara dengan penghematan sekitar 630 m³ air per hari. Hasil ini menunjukkan kelayakan dan efektivitas daur ulang air internal dalam produksi asam fosfat serta menegaskan potensi penerapan strategi sumber daya sirkular yang lebih luas di industri proses kimia
