从气体中脱除二氧化碳是这十年中最重要的分离任务之一。吸附过程可以在很大范围内对这一主题做出贡献，因此在研究和工业上分别进行了巨大的努力。在两种情况下，对变压吸附(PSA)和真空变压吸附技术的竞争力进行了评估：蒸汽甲烷重整以提高石油采收率从氢气生产中捕获碳，以及从直接还原炼铁过程中去除二氧化碳。此外，还必须考虑行业需求、项目和运营驱动。稳健性和稳定运行与优化资本支出和运营支出同等重要。考虑到经济和操作方面的问题，在本方案中，PSA工艺是最有吸引力的替代方案。
CO2 removal from gaseous streams is one of the most important separation tasks in this decade. Adsorption processes can contribute in a wide range to this topic, thus an enormous effort is performed respectively in research and industry. In two scenarios the competitiveness of pressure swing adsorption (PSA) and vacuum pressure swing adsorption technology is assessed: Carbon capture from hydrogen production by steam methane reforming for enhanced oil recovery and CO2 removal from direct reduction processes for iron making. Additionally, industrial requirements, project as well as operation driven, have to be considered. Robustness and stable operation is as important as optimized captial expenditure and operational expenditure. Considering economical and operational aspects PSA processes are the most attractive alternatives in the presented scenarios.
