Accelerated deployment of integrated CCUS chains based on solvent capture technology (AURORA)

为了减少二氧化碳密集型工业的排放，需要迅速扩大规模并部署更具成本效益和可持续的碳捕获解决方案。溶剂型碳捕集是一项重要的技术，可以很容易地应用于许多排放源。这种技术可以实现高捕获率，并以相对较低的能源需求提供高纯度的二氧化碳。在AURORA中，开放和非专有的CESAR1溶剂技术将被优化并符合商业部署的要求。该技术将在TRL7-8上展示，用于三个二氧化碳密集型行业：炼油、水泥和材料回收，对于这些行业来说，实现气候中和的其他选择很少。合作伙伴将展示可忽略不计的环境影响（排放是溶剂技术的潜在问题），与MEA溶剂的基准工艺相比，捕集率达到98%，捕集成本至少降低47%。这将通过以下创新实现：1)溶剂组成、工艺设计、排放监测和控制以及溶剂管理的整体优化；2)用于商业过程模拟器的验证模型；3)增强废热与碳捕获的集成，以减少外部热需求和运营成本；4)改进和集成先进的控制系统，以降低运营成本和优化性能。这些创新将集成在四个优化的捕获过程中，并在不同规模和复杂程度的试点中展示各个方面。合作伙伴将确保成果可转移到其他二氧化碳密集型行业，这要归功于项目中涉及的二氧化碳来源和发达集群的巨大变化，以及利益相关者的积极参与。该项目还将为其最终用户进行全面的CCUS链评估。值得注意的是，最终用户位于欧洲两个不同的地区，为CCUS价值链的实施提供了不同的条件。

Rapid up-scaling and deployment of more cost-efficient and sustainable carbon capture solutions is needed to reduce the emissions of CO2-intensive industries. Solvent-based carbon capture is an important technology that can be readily adopted to many emission sources. Such technology can achieve high capture rates and deliver CO2 at high purity with a relatively low energy demand. In AURORA the open and non-proprietary CESAR1 solvent technology will be optimised and qualified for commercial deployment. The technology will be demonstrated at TRL7-8 for three CO2 intensive industries: refining, cement, and materials recycling, for which there are few other options to achieve climate neutrality. The partners will demonstrate negligible environmental impact (emissions being a potential issue for solvent technology), capture rates at 98%, and capture costs reduced by at least 47% compared to a benchmark process with the MEA solvent. This will be achieved due to the following innovations: 1) Holistic optimisation of solvent composition, process design, emission monitoring and control, and solvent management, 2) Validated models for use in commercial process simulators 3) enhanced waste heat integration with carbon capture for reduced external heat demand and operational costs 4) Improved and integrated advanced control system for reduced OPEX and optimised performances. These innovations will be integrated in four optimised capture processes and various aspects will be demonstrated in pilots of various size and complexity. The partners will ensure transferability of results to other CO2 intensive industries thanks to the large variations in CO2 source and developed clusters addressed in the project and a strong stakeholder participation. The project will also do full CCUS chain assessments for its end-users. It is noteworthy that the end-users are situated in two different regions of Europe offering different conditions for the implementation of CCUS value chains.
