アンモニア産業は世界のCO2排出量の約2%を占める。本研究ではAspen Plusを用いて、CO2からメタノール、重曹、メタンを製造する3つのCCU経路を比較。重曹製造が最も経済性に優れ、年間利益約65百万ドル、IRR54%、投資回収期間5年、CO2削減率96%と推定された。
English
This study simulates three CO2 utilization pathways (methanol, sodium bicarbonate, methane) for the ammonia industry using Aspen Plus. Sodium bicarbonate production yields the best economic and environmental performance: annual profit $65 million, IRR 54%, payback time 5 years, and 96% CO2 emission reduction.

📄 Abstract（原文）
Global climate change is caused by high greenhouse gas (GHG) emissions. The industrial sector is one of the most significant contributors of emissions, particulary from production activities and the use of fossil fuels. The ammonia (NH3) industry is an important chemical sub-sector that still relies on fossil fuels and contributes 1.6 tons of CO2 emissions per ton of ammonia production, accounting for nearly 2% of global carbon emissions. Therefore, Carbon Capture Utilization (CCU) technology is needed to support the decarbonization of the industry. This study uses Aspen Plus V14 software for process simulation. Three CO2 utilization pathways were simulated: methanol production (CH3OH), sodium bicarbonate production (NaHCO3), and methane production (CH4). The result show that converting CO2 into sodium bicarbonate (NaHCO3) yields the most favorable result with a profit of $65,277,360/year, a positive NPV of $840,647,028, an IRR exceeding the bank interest rate (10%) at 54%, and a POT in the fifth year. Additionally, sodium bicarbonate is environmentally sustainable, as evidenced by a CO2 emission reduction rate of 96%. The assessment was carried out under the assumptions of stable market conditions, sufficient availability of green hydrogen and ideal operating parameters, However, this study acknowledges inherent limitations, including catalyst performance, high energy requirements, and the challenge of integration with existing infrastructure, which may hinder large-scale implementation.
