在以往的研究中，提出了一种基于斯特林制冷机的新型低温CO2捕集系统。作为现有CO2减排技术的替代方案，开发的低温方法具有潜力。然而，应该注意的是，与分离的流（例如冷凝水、残余气体和捕获的CO2）相关的显热和潜热是相当大的。因此，提出了开发的低温CO2气体分离过程的热集成，以进一步降低总能量输入。具体地说，冷凝水的潜热，残余气体和CO2产品的显热回收换热网络。为了评价低温CO2捕集器的捕集性能，采用商业软件白杨Plus对有无热集成的低温CO2捕集过程进行了模拟。结果表明，建议的系统与热集成单元的能量需求可以减少88.06 MW的总195.29 MW，当应用该过程的典型600 MW燃煤电厂的烟气。
In previous research, a novel cryogenic CO2capture system based on Stirling coolers was outlined. As an alternative for existing CO2mitigation techniques, the developed cryogenic approach has potential. However, it should be noted that sensible and latent heat associated with the separated streams (such as condensate water, residual gas and captured CO2) is substantial. Therefore, heat integration of the developed cryogenic CO2gas separation process is proposed to further reduce the total energy input. In detail, the latent heat of condensate water, the sensible heat of residual gas and CO2product is recovered by heat exchanger networks. In order to evaluate the capture performance, the cryogenic CO2process with and without heat integration is simulated by commercial software Aspen Plus. The results indicate that the energy requirement of the proposed system with heat integration units can be decreased by 88.06 MW over a total of 195.29 MW, when applying the process to the flue gases of a typical 600 MW coal power plant.
