利用霍尼韦尔UniSim R400模拟了一个典型的10兆瓦生物质燃料热电联产电厂，该电厂配备了一个FICFB（快速内循环流化床）气化炉和一个Jenbacher 6型燃气发动机，以估计其功率和热输出。生物质气化热电联产装置与燃烧前吸附捕集工艺或传统燃烧后胺工艺相结合，以实现负碳发电和供热。应用于合成气流的吸附式co2捕集工艺可实现的实际最大碳捕集率为49%，而胺法可将碳捕集率提高到59%。然而，研究发现，两级两床PVSA（压力真空变吸附）装置比传统的胺工艺有明显的优势，与PVSA装置集成的热电联产装置比与胺工艺集成的热电联产装置可以实现1.7%的净电效率和12.8%的净热效率。
An exemplary 10 MWthbiomass-fuelled CHP plant equipped with a FICFB (Fast Internally Circulating Fluidised Bed) gasifier and a Jenbacher type 6 gas engine was simulated using Honeywell UniSim R400 to estimate the power and thermal outputs. The biomass gasification CHP plant was integrated with either a pre-combustion adsorptive capture process or a conventional post-combustion amine process to achieve carbon-negative power and heat generation. The practical maximum of carbon capture rate achievable with an adsorptive CO2capture process applied to a syngas stream was 49% in overall while the amine process could boost the carbon capture rate up to 59%. However, it was found that the two-stage, two-bed PVSA (Pressure Vacuum Swing Adsorption) unit would have a clear advantage over the conventional amine processes in that the CHP plant integrated with the PVSA unit could achieve 1.7% points higher net electrical efficiency and 12.8% points higher net thermal efficiency than the CHP plant integrated with the amine process.
