Abstract

Perancangan pabrik amonia biru ini bertujuan untuk memproduksi amonia (NH₃) dengan integrasi teknologi Carbon Capture and Utilization (CCU) guna menghasilkan produk samping natrium karbonat (NaHCO₃). Pabrik dirancang dengan kapasitas produksi amonia maksimal sebesar 4.000 ton/hari, menggunakan gas alam sebagai bahan baku utama untuk menghasilkan hidrogen melalui proses Autothermal Reforming (ATR), sedangkan nitrogen diperoleh dari Air Separation Unit (ASU) atau melalui supplier. Hidrogen dan nitrogen kemudian disintesis menjadi amonia melalui proses KAAP (Kellogg Advanced Ammonia Process) pada tekanan sekitar 90 bar dan suhu 350–450°C menggunakan katalis berbasis ruthenium. Gas CO₂ hasil samping proses reforming dimanfaatkan melalui integrasi CCU dengan mereaksikannya bersama larutan NaOH untuk menghasilkan natrium karbonat/karbonat, sehingga emisi karbon dapat ditekan sekaligus memberikan nilai tambah ekonomi. Perancangan ini mencakup pengembangan Process Flow Diagram (PFD), neraca massa dan energi, analisis HAZOP dan P&ID, serta analisis ekonomi dan lingkungan. Diharapkan pabrik ini mampu mendukung transisi energi rendah karbon di Indonesia dengan memanfaatkan gas alam secara efisien serta mengurangi ketergantungan impor Na₂CO₃ melalui penerapan konsep ekonomi sirkular karbon.

The design of this blue ammonia plant aims to produce ammonia (NH₃) integrated with Carbon Capture and Utilization (CCU) technology to generate sodium carbonate (NaHCO₃) as a byproduct. The plant is designed with a maximum production capacity of 4,000 tons per day, utilizing natural gas as the main feedstock to produce hydrogen through the Autothermal Reforming (ATR) process, while nitrogen is obtained from an Air Separation Unit (ASU). Hydrogen and nitrogen are then synthesized into ammonia through the KAAP (Kellogg Advanced Ammonia Process) at a pressure of approximately 90 bar and a temperature of 350–450°C, using a ruthenium-based catalyst. The CO₂ byproduct from the reforming process is utilized through CCU integration by reacting it with a sodium hydroxide (NaOH) solution to produce sodium carbonate/carbonate, thereby reducing carbon emissions while creating additional economic value. This design project includes the development of a Process Flow Diagram (PFD), mass and energy balance, HAZOP and P&ID analysis, as well as economic and environmental evaluations. The establishment of this plant is expected to support Indonesia’s transition toward low-carbon energy by efficiently utilizing natural gas resources and reducing the dependency on imported Na₂CO₃ through the implementation of a carbon circular economy concept.
