本研究は、バイオディーゼル製造における蒸留塔の排気ガス削減を目的とし、単一凝縮器と二重凝縮器のプロセスを比較した。その結果、105℃で運転した二重凝縮器構成（シナリオ4）が最も低い排出値を示し、一酸化炭素0.9%、二酸化炭素4.4%、総炭化水素804ppm、地球温暖化評価0.0012kg CO2 eqを達成した。プロセス最適化により炭素フットプリントの低減が可能である。
English
This study compares single- vs two-condenser distillation processes in biodiesel production to reduce exhaust emissions. The two-condenser setup at 105°C (Scenario 4) achieved the lowest emissions: CO 0.9%, CO2 4.4%, THC 804 ppm, and a global warming potential of 0.0012 kg CO2 eq. Process optimization significantly reduces the carbon footprint of biodiesel plants.

日本のGX文脈において
日本ではバイオディーゼルは主要なGXテーマではないが、蒸留プロセスの省エネ・低炭素化手法として参考になる。特に中小規模バイオ燃料プラントの環境負荷低減に寄与する可能性がある。
In the global GX context
Globally, biodiesel production is expanding, and process optimization for carbon footprint reduction is relevant to life cycle assessment and carbon accounting. The two-condenser design offers a practical, low-cost improvement for existing plants.

📄 Abstract（原文）
Distillation columns play a central role in biodiesel production by facilitating the effective separation and purification processes that are crucial for ensuring product quality. Operating under reactive or conventional configurations, these columns are significant sources of energy demand and can generate emissions, particularly when methanol or other volatile by-products are released during the separation process. Integrating heat exchangers into the system enables energy recovery and process optimisation. This reduces the net energy input and helps to decrease the plant's overall carbon footprint. This study aimed to compare exhaust emissions from a single-condenser distillation process with those from a two-condenser distillation process. Additionally, it delves into the utilization of cooling media in either configuration, exploring the differences in their application. The study found that the lowest emission values were seen at 105°C in Scenario 4, with carbon monoxide at 0.9%, carbon dioxide at 4.4%, and total hydrocarbons at 804 ppm, as well as a global warming evaluation of 0.0012 kg CO₂ eq, a eutrophication evaluation of 0.0001 kg PO 4 eq, and an acidification evaluation of kg SO₂ eq.
