| 摘 要： | 如何减排CO2是全世界都十分关注的问题。对中国而言,传统燃煤电厂的直接燃烧是CO2排放的主要来源。目前世界各国都在研究燃煤电厂CO2捕捉问题,但因此引起的效率损失太大,使人"望而却步"。本文提出并详细分析了空气气化IGCC加上变换与CO2分离的新系统,其系统效率降低幅度大大小于纯氧气化工艺的IGCC系统,仅降低5.4个百分点)相对于纯氧气化的7.5个百分点),这类准零排放的IGCC系统效率仍能达到41.2%,为减排CO2开辟了一条新的道路。

| Abstract: | CO2 emission reduction is an important problem which gets more and more attention from all over the world.To China,CO2emission is mainly from traditional pulverized coal power plants.Currently,many countries are working hard on CO2 capture in coal power plants.However the efficiency loss due to CO2 capture is too much to take action.This paper put forward a new IGCC system which adopts air-blown gasification,shift and CO2 separation.The new system which efficiency loss is much less than that of oxygen-blown gasification IGCC system,is 5.4 percentage points(compared with 7.5 percentage points).The efficiency of new system with CO2 capture can still up 41.2%,which make a new option for CO2 emission control.Figs 11,tables 2 and refs5. |
