Abstract

Berdasarkan peningkatan permintaan amonia di Indonesia sekaligus urgensi transisi energi menuju Net Zero Emission, Tugas Akhir ini merancang pendirian pabrik Blue Ammonia berkapasitas 450.000 ton/tahun yang berlokasi di Banggai, Sulawesi Tengah, sebuah lokasi strategis yang dipilih karena ketersediaan gas alam yang melimpah. Proses produksi utama menerapkan teknologi Steam Methane Reforming (SMR) yang terintegrasi dengan unit Carbon Capture Utilization (CCU) berbasis pelarut MDEA untuk memisahkan emisi karbon secara efisien. Desain pabrik juga dirancang guna mereduksi emisi CO2 dan diubah menjadi produk bernilai tambah guna mengurangi ketergantungan impor, meliputi produksi natrium karbonat berkapasitas 57.217.755 ton/tahun melalui proses karbonasi NaOH. Lingkup perancangan mencakup penyusunan neraca massa dan energi, diagram instrumentasi (P&ID), studi keselamatan proses (HAZOP), serta analisis kelayakan ekonomi dengan asumsi masa konstruksi 1 tahun dan umur operasi 20 tahun. Berdasarkan evaluasi finansial, pabrik ini dinyatakan layak untuk didirikan dengan indikator keuntungan yang solid, ditunjukkan oleh nilai Internal Rate of Return (IRR) sebesar 20,83%, Net Present Value (NPV) positif sebesar $ 4.066.126.994,64, dan waktu pengembalian modal (Pay Out Time) selama 5 tahun.

Based on the increasing demand for ammonia in Indonesia and the urgency of the energy transition toward Net Zero Emissions, this Final Project proposes the design of a Blue Ammonia plant with a production capacity of 450,000 tons per year, located in Banggai, Central Sulawesi, a strategic site selected due to its abundant natural gas resources. The main production process employs Steam Methane Reforming (SMR) technology integrated with a Carbon Capture and Utilization (CCU) unit utilizing MDEA solvent to efficiently separate carbon emissions. The plant is also designed to reduce CO₂ emissions by converting captured carbon into value-added products, thereby reducing import dependency, including the production of sodium carbonate with a capacity of 57.217.755 tons per year through the carbonation of NaOH. The scope of the design includes the preparation of mass and energy balances, Piping and Instrumentation Diagrams (P&ID), Hazard and Operability Studies (HAZOP), and an economic feasibility analysis assuming a one-year construction period and a twenty-year operational lifetime. Based on the financial evaluation, the project is considered economically feasible, as indicated by strong profitability indicators, including an Internal Rate of Return (IRR) of 20,83%, a positiv Net Present Value (NPV) of USD 4.066.126.994,64, and a Pay Out Time (POT) of 5 years.
