波特兰水泥制造等工业过程产生了很大比例的人为二氧化碳，如果没有碳捕获和封存，大幅减少其排放可能是困难或昂贵的。本文探讨了碳捕获和封存装置的停机与工业现场主要工艺装置翻新所需的主要停机同步的想法。它首次开发了一个详细的自下而上模型，并将其应用于英国的水泥行业。这项研究表明，一些政策和技术风险没有被自上而下的模型识别出来，它强调了减少捕获工厂建设的关闭时间的重要性。如果做不到这一点，安装成本可能会增加约10%。这种方法是对自上而下建模的补充，从这种方法中吸取的经验教训可以应用于其他资本和能源密集型行业，如初级钢铁生产。它提供了关于应优先采取哪些行动的重要信息，以确保在不额外不必要的关闭的情况下实施碳捕获和封存，这将增加二氧化碳减排的总体成本，并可能推迟行动，从而增加累积排放量。
Industrial processes such as Portland cement manufacture produce a large proportion of anthropogenic carbon dioxide and significantly reducing their emissions could be difficult or expensive without carbon capture and storage. This paper explores the idea of synchronising shutdowns for carbon capture and storage installation with major shutdowns required to refurbish major process units at industrial sites. It develops a detailed bottom-up model for the first time and applies it to the United Kingdom's cement industry. This research demonstrates that several policy and technology risks are not identified by the top-down models and it highlights the importance of reducing shut-down times for capture plant construction. Failure to do so could increase installation costs by around 10 per cent. This type of approach, which is complementary to top-down modelling, and the lessons learned from it can be applied to other capital- and energy-intensive industries such as primary steel production. It provides important information about what actions should be prioritised to ensure that carbon capture and storage can be applied without extra unnecessary shutdowns which would increase the overall cost of carbon dioxide mitigation and could delay action, increasing cumulative emissions as well.
