Abstract:

Temperature swing adsorption (TSA) technology for carbon capture is one of the effective means to control carbon emissions and achieve the targets of “carbon emission peak” and “carbon neutrality”. However, due to the lack of a relatively complete measurement system and an executable standardized test scheme, the test results of unit performance are quite different, and the difficulty in grasping the trend and performance iteration caused by the lack of regularity is not conducive to the industrial development of TSA. In this paper, a standardized test scheme including test conditions, performance evaluation indicators, data measurement and collection was initially proposed, and the performance test of the physical unit of the prototype scale was carried out. The results showed that the scheme was highly executable and can provide reference for the performance evaluation of related units. In addition, the performance test results of the unit showed that the operation state of the unit was easy to control, and the purity and recovery rate could reach more than 90%, but the energy efficiency was between 3.5% and 6.5%, with great potential for improvement. The benchmarking analysis found that the loss of energy consumption of pipes and other components in the unit accounts for 30%—40%. Therefore, it was necessary to further reduce consumption and improve efficiency by optimizing the pipeline layout, improving the heat exchange efficiency in the adsorption chamber, and optimizing the desorption temperature, vacuum pressure and other operating parameters.

摘要:

变温吸附(TSA)碳捕集技术是控制碳排放进而实现“双碳”目标的有效保障手段之一。然而,由于目前缺乏相对完善的计量体系和可执行的标准化测试方案,导致机组性能的测试结果差别较大,缺乏规律性所造成的趋势和性能迭代困难不利于TSA产业化发展。本文初步提出了包含测试工况、性能评价指标、数据的测量与采集三个方面的标准化测试方案,并对样机规模的实物机组进行了性能测试。结果表明,该套方案的可执行度高,可为相关机组的性能评价工作提供借鉴。此外,机组的性能测试结果显示,该机组的运行状态容易控制,纯度和回收率最高均能达到90%以上,但是能源效率在3.5%~6.5%之间,提升潜力大。对标分析发现机组内的管道等部件损失的能耗占比30%~40%,所以需要通过优化管道线路布置、提高吸附腔内换热效率、优化解吸温度和真空压力等运行参数等方式来进一步降耗提效。
