在“碳达峰、碳中和”背景下，传统化工企业都将面临CO₂排放指标限制难题。CCUS（碳捕集、利用与封存）技术是解决CO₂排放难题的关键一招，化工企业首先需要依靠CO₂尾气捕集回收装置，实现上游源头减碳，再通过下游资源利用，进而形成经济可行的CCUS产业链。针对传统CO₂尾气回收装置建设过程中存在的占地面积大，土建费用高，灵活性差，施工周期长等突出问题，研发出模块化撬装化CO₂回收技术，可以有效降低前期投资成本和缩短施工周期。该技术根据装置工艺功能单元特点，基于模块化设计实现回收工艺模块划分，达到100%工厂化预制，现场模块化施工标准。同时，利用撬装化设计，合理布局管道阀门，实现模块内设备优化整合成撬，最终形成全流程模块化撬装化的CO₂回收装置。现场应用结果表明，相比传统CO₂尾气回收装置，模块化撬装化5×10⁴ t/a煤制氢CO₂尾气回收装置完全达到降低投资成本和缩短施工周期目标，其中土建费用降低74.0%，建设面积降低75.2%，工程施工周期缩短50.0%。

Under the background of “carbon peak and carbon neutrality”, traditional chemical enterprises are encountering challenges due to CO₂ emission limitations. CCUS（Carbon Capture, Utilization and Storage） technology emerges as a crucial strategy for addressing CO₂ emissions. To mitigate emissions at the source, chemical companies are turning to CO₂ flue gas capture and recovery technologies, while also exploring ways to integrate these efforts into a cost-effective CCUS industrial chain. To overcome the drawbacks of traditional CO₂ flue gas recovery units, such as large land use, high construction costs, inflexibility, and lengthy construction times, the modular skid-mounted CO₂ recovery technology has been introduced. This innovative approach minimizes upfront investment and accelerates project timelines by modularizing the recovery process, allowing for 100% factory prefabrication and streamlined on-site assembly. The skid-mounted design efficiently organizes pipelines and valves, integrating equipment within each module onto skids, resulting in a fully modular skid-mounted CO₂ recovery unit. Field applications demonstrate significant advantages of the modular skid-mounted approach over conventional methods. For example, a 5×10⁴ tons per year coal-to-hydrogen CO₂ flue gas recovery unit saw a 74.0% reduction in construction costs, a 75.2% decrease in required space, and a 50.0% shorter construction timeline, effectively meeting the objectives of cost reduction and expedited project completion.
