In 2018, the International CCS Knowledge Centre (CCS Knowledge Centre) conducted a feasibility study with SaskPower to determine if a business case could be made for a postcombustion, carbon capture retrofit of SaskPower's Shand Power station, a 305‐MW, single‐unit, lignite coal‐fired power station located near Estevan, Saskatchewan. Specifically, Mitsubishi heavy industries’ KM CDR technology was evaluated for this study. While no decision has been made, should SaskPower decide to proceed, the Shand carbon capture and storage (CCS) project would produce the second, full‐scale capture facility in Saskatchewan with a nominal capacity of 2 million tonnes of CO₂ (Mt) per year. This paper summarizes the key technical and economic findings of this study. Notably this study found that the capital costs of the potential Shand CCS facility are decreased by 67% on a per tonne of CO₂ captured basis when compared to the CCS retrofit of Unit 3 at the Boundary Dam Power Station (the world's first industrial scale CCS installation on a coal fired power station). The proposed capture facility would also have a load following operational profile, reduction in parasitic loses by employing heat integration strategies, and need no additional water draw to provide the required increase in cooling duty. © 2020 The Authors.

在燃煤电厂上安装第二代CCS设施–可行性研究的结果，以用CCS改造SaskPower的Shand电厂

2018年，国际CCS知识中心（CCS知识中心）与SaskPower进行了可行性研究，以确定是否可以为SaskPower的Shand电站（305兆瓦，单机组，萨斯喀彻温省埃斯特万附近的褐煤火力发电厂。具体而言，本研究评估了三菱重工的KM CDR技术。尽管尚未做出任何决定，但如果SaskPower决定继续进行，Shand碳捕集与封存（CCS）项目将在萨斯喀彻温省生产第二座全面捕集设施，标称容量为200万吨CO ₂（Mt）每年。本文总结了这项研究的关键技术和经济发现。值得注意的是，这项研究发现，与边界大坝电站3号机组的CCS改造（世界上第一个工业规模CCS）相比，潜在的Shand CCS设施的资本成本以每吨CO ₂捕获量计算减少67％。安装在燃煤电站上）。拟议的捕集设施还将具有遵循运行状况的负载，通过采用热集成策略来减少寄生损失，并且不需要额外的取水来提供所需的冷却能力增加。©2020作者。温室气体：化学工业协会和John Wiley＆Sons，Ltd.出版的科学和技术。
