摘要：
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. © 2023 Chemical Industry Press.
