基于ASPEN PLUS的CCRs碳捕捉系统技术经济性分析

Techno-economic analysis of fossil-fuelled power generation systems with the multiple cyclic CCRs process

钙基吸收剂循环煅烧/碳酸化法(CCRs)是一项具有发展潜力的燃烧后碳捕捉技术。采用商业软件ASPEN PLUS对循环过程进行模拟,讨论CCRs碳捕捉系统能量回收问题,以及对引入电厂后的该碳捕捉系统进行初步的技术经济性分析。

With global w arming w orsening,CO2 emission from coal combustion is attracting more public concerns for its leading adverse effect in global w arming. Carbon capture and storage technology( CCS) applied to coal-fired power plant is around the corner. In many methods for CCS,the carbonate looping process is a promising technology for post-combustion CO2 capture from pow er plants. CO2 capture is performed in a system of tw o fluidized bed reactors. In this paper,material and energy of the process have been performed using ASPEN PLUS. The present study focuses on energy recovery of CCRs system and preliminarily techno-economic analysis of the pow er plant after the introduction of carbon capture systems.
