Bioenergy with carbon capture and storage is considered as an effective method for CO reduction. Conventional monoethanolamine-based CO capture technologies are usually not cost-effective due to the high energy consumption caused by CO regeneration and compression. This study proposed a green ammonia-based decarbonization system to capture CO from the biomass flue gas while producing highly purified NHHCO. The system is based on a 30 MW biomass power plant, integrating a 99.70 MW PV unit and a 3.34 t/h NH production system as the source of NH. In total, 46490.96 t/yr. of CO, equivalent to 16.34 % of the total CO generation by biomass combustion, can be removed while producing 83308.33 t/yr. of solid NHHCO. In addition, the turbine output increases by 411.96 kW averagely due to the waste heat recovery from the NH production system. Integrated with the decarbonization system, the biomass power plant has the net CO emission of −1,105,965 t and the CO emission factor of −174 gCO/kWh through its lifespan of 30 years, and leads to an additional expense with the net present value of 28.57 MM$. Assuming all the products and byproducts can be sold in the market, the decarbonization cost is as low as 20.70 $/t.

基于绿色氨的生物质发电厂燃烧后 CO2 捕获和 NH4HCO3 生产集成系统的性能评估


具有碳捕获和储存的生物能源被认为是减少二氧化碳的有效方法。由于二氧化碳再生和压缩造成的高能耗，传统的基于单乙醇胺的二氧化碳捕集技术通常不具有成本效益。本研究提出了一种绿色氨基脱碳系统，从生物质烟气中捕获 CO，同时生产高纯度的 NH4HCO。该系统以30MW生物质发电厂为基础，集成99.70MW光伏机组和3.34t/hNH生产系统作为NH源。总计 46490.96 吨/年。相当于生物质燃烧产生的 CO 总量的 16.34%，可去除 83308.33 吨/年。固体NHHCO。此外，由于NH生产系统的余热回收，汽轮机输出平均增加411.96kW。结合脱碳系统，生物质发电厂30年寿命期间CO净排放量为-1,105,965 t，CO排放因子为-174 gCO/kWh，产生的额外费用净现值为28.57 MM$。假设所有产品和副产品均可在市场上销售，脱碳成本低至20.70美元/吨。
