摘要

碳捕集、利用与封存（CCUS）技术是实现CO

减排的重要技术，然而捕集能耗较高是限制CCUS技术大规模推广的重要问题之一。为降低捕集能耗，针对钙铜循环CO

捕集技术中朗肯循环回收高品位余热效率较低的问题，提出了一种新型钙铜-联合循环燃烧后CO

捕集技术。以水泥厂烟气为捕集源，采用Aspen Plus软件搭建模型进行流程模拟，对典型钙循环水泥厂集成系统（系统I）、传统钙铜循环水泥厂集成系统（系统II）和新型钙铜-联合循环水泥厂集成系统（系统III）进行了热力性能与经济成本分析，并研究了部分操作参数对系统III热力性能的影响。结果表明，在90%碳捕集率、针对单位质量CO

时，系统III减排CO

的一次能源消耗为-0.87 MJ/kg，系统III减排成本为265.8 CNY/t；与系统I和系统II相比，系统III减排单位质量CO

的一次能源消耗分别减少了2.91 MJ/kg和2.00 MJ/kg，减排成本分别降低了42.67%和41.41%；在一定条件下，降低CO

捕集率、提升煅烧器温度或提升空气反应器温度，均可降低系统III减排能耗；当空气反应器温度为950 ℃时，压力为1.5 MPa可使系统III达到最低能耗（-0.87 MJ/kg）。

Abstract

Carbon capture

utilization and storage (CCUS) technology is essential for achieving CO

emission reduction. However

the high energy consumption of the capture processes is a significant barrier to the widespread adoption of CCUS technology. To address this issue

the low efficiency of waste heat recovery in the Rankine cycle of Ca and Cu looping CO

capture technology

a novel Ca and Cu-combined looping post-combustion CO

capture technology is proposed. Using cement plant flue gas as the capture source

a process simulation model was constructed using Aspen Plus software. Thermodynamic performance and economic cost analysis were conducted for the typical Ca looping cement plant integrated system (system I)

the conventional Ca and Cu looping cement plant integrated syst

em (system II)

and the novel Ca and Cu-combined looping cement plant integrated system (system III). Additionally

the impact of various operational parameters on the thermal performance of system III was investigated. The results indicate that under carbon capture rate of 90% and according to unit mass CO

the primary energy consumption for CO

reduction in system III is -0.87 MJ/kg and the reduction cost is 265.8 CNY/t. Compared to system I and system II

the primary energy consumption for CO

reduction in system Ⅲ decreases by 2.91 MJ/kg and 2.00 MJ/kg

respectively

while the reduction cost decreases by 42.67% and 41.41%

respectively. Under certain conditions

reducing the CO

capture rate

increasing the calciner temperature or increasing the air reactor temperature can reduce the energy consumption of system III. When the air reactor temperature is 950 ℃

system III with pressure of 1.5 MPa can lead to the lowest energy consumption (-0.87 MJ/kg).
