CCS is expected to be one of the major measures contributing to carbon reduction and meet net zero emission in near future. Fossil fuel power plants equipped with CCS can be considered to be zero-carbon power generation if nearly full CO₂ recovery is feasible. The objective of this paper is to investigate the process performance and plant economics at 99.5% CO₂ capture ratio that has not been studied before using MHIENG’s CO₂ capture technology. It is expected that this work using experiences and empirical data that MHIENG has accumulated is more indicative of current commercial CCS technology and economics than previous work. The near-zero emission design proposed in this work using 50% additional absorption packing achieves 99.5% capture ratio with similar normalized OPEX ($/tonne CO₂) and 6% higher normalized CAPEX compared to base case at 90% capture ratio. Near-zero emission coal-fired power plant is technically feasible using the Advanced KM CDR Process™ and KS-1™ solvent and will increase cost of CO₂ captured by 3% compared to default design at 90% capture ratio.

预计CCS将是有助于减少碳排放并在不久的将来实现净零排放的主要措施之一。配备有CCS化石燃料发电厂可被认为是零碳发电如果几乎充满CO ₂恢复是可行的。本文的目的是研究在使用MHIENG的CO ₂之前尚未研究过的99.5％CO ₂捕集率下的工艺性能和工厂经济性。捕获技术。可以预期，使用MHIENG积累的经验和经验数据进行的这项工作比以前的工作更能说明当前的商业CCS技术和经济学。在这项工作中提出的使用接近50％的吸收填料的近零排放设计，在90％捕获率的情况下，与基本情况相比，归一化OPEX（$ / tCO ₂）的捕获率达到99.5％，归一化CAPEX则高出6％。使用Advanced KM CDR Process™和KS-1™溶剂在技术上是接近零排放的燃煤电厂，与90％捕集率的默认设计相比，CO ₂捕集成本将提高3％。
