摘要
在“碳达峰、碳中和”背景下,传统化工企业都将面临CO_(2)排放指标限制难题。CCUS(碳捕集、利用与封存)技术是解决CO_(2)排放难题的关键一招,化工企业首先需要依靠CO_(2)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CO_(2)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CO_(2)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CO_(2)回收装置。现场应用结果表明,相比传统CO_(2)尾气回收装置,模块化撬装化5×10^(4) t/a煤制氢CO_(2)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 CO_(2) emission limitations.CCUS(Carbon Capture,Utilization and Storage)technology emerges as a crucial strategy for addressing CO_(2) emissions.To mitigate emissions at the source,chemical companies are turning to CO_(2) 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 CO_(2) flue gas recovery units,such as large land use,high construction costs,inflexibility,and lengthy construction times,the modular skid-mounted CO_(2) 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 CO_(2) recovery unit.Field applications demonstrate significant advantages of the modular skid-mounted approach over conventional methods.For example,a 5×10^(4) tons per year coal-to-hydrogen CO_(2) 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.
