Boosting Reduction of Energy Intensity in cleaN STeelwork platfORM

就能源需求和温室气体（GHG）排放而言，钢铁是英国最大的制造业。目前，两家钢铁厂的六座高炉每年生产600多万吨钢铁，钢铁的具体能耗为19吉焦/吨，总直接二氧化碳排放量为1300万吨，占英国制造业温室气体排放量的25%。电站燃烧高炉煤气产生的二氧化碳排放量约占总排放量的50%。在BREIN-STORM中，我们建议将炼钢厂的BFG转化为有价值的产品，如氢气和纯二氧化碳。这将通过结合钙和化学环气固反应（CaL-CLC）来实现。这个为期四年的项目包括四个相互关联的工作包：WP1将开发和扩大以氧化钙为吸附剂和氧化铜为氧载体的不同多功能材料。我们将重点提高循环操作的稳定性和材料的吸附能力。生产的材料将进行测试和表征，以检查寿命。动力学模型将被导出，以使规模扩大。WP2将专注于反应堆的开发和测试。我们将在填料床和流化床配置中进行不同反应条件下的实验论证和长期测试。实验结果将用于验证反应器模型。从实验和数值活动中获得的知识将作为该技术未来中试示范的指导。在WP3中，CaL-CLC工艺将通过概念设计融入炼钢厂。该工艺的技术经济性能将与钢铁行业标准的最先进技术进行比较。将研究可再生能源的整合，目的是设计第一个“绿色”钢铁厂。在第四阶段工作计划中，将评估已制订的程序对环境的影响，以及对社会和政策的影响。

Iron and steel is the largest UK manufacturing industry in terms of energy demand and greenhouse gas (GHG) emissions. Currently, more than 6 Mt of steel per year are produced in six blast furnaces at two steelworks with specific energy consumptions of 19 GJ/t of steel and overall direct CO2 emissions of 13 Mt, contributing 25% to GHG emissions from UK manufacturing. Combustion of blast furnace gas (BFG) in the power station causes ~ 50% of CO2 emissions.In BREIN-STORM we propose to convert the BFG from steel mills into valuable products, such as hydrogen and pure carbon dioxide. This will be achieved by combining calcium and chemical looping gas-solid reactions (CaL-CLC). This four-year project comprises four interlinked work packages (WPs):1. WP1 will develop and scale up different multi-functional materials based on calcium oxide as sorbent and copper-oxide oxygen carriers. We will focus on increasing the stability over cycling operation and the sorption capacity of the materials. The produced material will be tested and characterised to examine longevity. The kinetics models will be derived to enable the scale up.2. WP2 will focus on the development and testing of the reactor. We will carry out the experimental demonstration and long-term testing under different reactive conditions in packed and fluidised bed configurations. The experimental results will be used to validate the reactor model. The knowledge gained both from the experimental and numerical activities will be used as guidance for future pilot-scale demonstration of the technology.3. In WP3, the CaL-CLC process will be integrated into the steelworks through a conceptual design. The techno-economic performance of the process will be compared with standard state-of-the-art technologies in the steel sector. The integration of renewables sources will be studied with the aim of designing a first 'green' steelworks plant.4. In WP4, the developed process will be evaluated on environmental impacts as well as social and policy implications.
