摘要

基于Aspen Plus软件建立了高温钙基吸附剂碳捕集的系统模型

开展了1 000 MW燃煤机组烟气CO

捕集工艺流程模拟研究。针对煅烧炉煤富氧燃烧供能存在的高能耗与污染物排放问题

提出采用外部电加热供能方式为煅烧炉提供热量。详细考察了烟气进入碳捕集系统后

系统关键性能参数的变化;在此基础上分析了系统的能量和物质守恒情况

以及不同操作参数对系统性能的影响。结果表明:当1 000 MW燃煤发电机组增加碳捕集系统后

发电热效率将下降26.11%;碳化炉温度稳定在645 ℃时

捕集效率可达92.13%;煅烧炉温度设定在900 ℃时

CaCO

会分解得更彻底;碳酸化炉温度的提升会减少煅烧能耗并提高发电热效率

而煅烧温度的升高会增加能耗并降低发电热效率;钙碳摩尔比的增加导致钙基碳捕集系统的固体循环量增加

而钙基吸附剂的平均碳转化率则呈现出负相关性。

Abstract

Based on Aspen Plus software

a carbon capture system model of high-temperature Ca-based adsorbent was established

and simulation study was carried out for CO

capture process of flue gas in a 1 000 MW coal-fired unit. Aiming at the problems of high energy consumption and pollutants emission in energy supply of oxygen-enriched coal combustion in calciner

external electric heating energy supply was proposed to provide heat for calciner. The changes in key performance parameters after flue gas entering the carbon capture system

were investigated in detail. On this basis

the conservation of energy and mass

as well as the effects of different operating parameters on system performance were analyzed. Results show that after the carbon capture system is added in the 1 000 MW coal-fired generating unit

the thermal efficiency of electricity generation will decrease by 26.11%. When the temperature of the carbonization furnace is maintained at 645 ℃

capture efficiency will be 92.13%. CaCO

will be decomposed more thoroughly when the calcination furnace temperature is set at 900 ℃. The increase of temperature in carbonation furnace will reduce energy consumption of calcination and improve thermal efficiency of power generation

while the increase of calcination temperature will increase energy consumption and reduce thermal efficiency of power generation. The increase in calcium-carbon molar ratio leads to the increase of solid circulation in the calcium-based carbon capture system

while average carbon conversion of calcium-based adsorbents shows negative correlation.
