クラフトパルプ工場にバイオマスガス化を統合し、グリーンアンモニアを生産する技術経済性を評価。KraftSIMモデルにより、アンモニア収率約0.51 t/BDMT、蒸気・温水の副生によるユーティリティ負荷低減、PSAテールガス等のボイラー燃焼による効率向上を確認。経済性はバイオマス調達コストや電力価格、グリーン燃料市場プレミアムに強く依存し、バイオ炭素価格の導入で収益性が向上する可能性を示す。
English
Techno-economic assessment of integrating biomass gasification into kraft pulp mills for green ammonia production using KraftSIM modeling. The process yields ~0.51 t ammonia per BDMT while generating steam and hot water that offset mill utility demands. Economic analysis suggests net revenue of ~CA$380/BDMT, strongly influenced by biomass procurement costs, electricity prices, and green fuel market premiums. The design enables gradual scale-up without disrupting the recovery cycle.

📄 Abstract（原文）
As the global energy sector transitions toward net-zero emissions, kraft pulp mills present a compelling opportunity to produce green fuels and achieve net-negative emissions by capturing biogenic carbon, helping offset hard-to-abate sectors. This study explores the techno-economics of integrating biomass gasification for green ammonia production within kraft mills, using KraftSIM modeling to evaluate ammonia production, steam balance, emissions, and utility impacts. The proposed design enables energy and water system integration with the existing mill and allows for a gradual scale-up without disrupting the chemistry and operation of the recovery cycle. Across five scenarios representing different biomass gasification rates ranging from 100 to 1000 bone-dry metric tons per day (BDMT/d), the process yields ammonia at approximately 0.51 metric tons per bone-dry metric ton (t/ BDMT), while generating significant low- and medium-pressure steam and hot water that offset mill utility demands. The incineration of pressure swing adsorption tail gas and ammonia plant purge gas in the power boiler reduces biomass combustion and enhances power boiler efficiency. Economic analysis suggests a net revenue potential of approximately CA$380/BDMT, which could increase with the implementation of biogenic carbon pricing. Overall profitability is strongly influenced by biomass procurement costs, electricity prices, and prevailing green fuel and chemical market premium. This work outlines a practical, near-term decarbonization pathway for kraft mills by coupling green fuel production with potential opportunities for carbon removal.
