燃气-蒸汽联合循环电厂实施碳捕集的可行性研究

Feasibility study of retrofitting carbon capture sysetem for gas-steam combined cycle power plant

以杭州某电厂390 MW燃气-蒸汽联合循环机组为对象,研究了增设碳捕集装置的可行性。针对燃气轮机排烟进行了吸收液筛选,选定了一种低能耗吸收液。根据回收规模的不同,制订了全捕集、捕集量为0.5 t/h和捕集量为1.0 t/h 3个典型方案,并进行经济技术分析。结果表明,捕集能力为1.0 t/h的方案具有可行性,且经济性最佳,故为推荐方案。

With 390 MW gas-steam combined cycle units of on power plant in Hangzhou as object,the paper studied feasibilit of increasing device of carbon capture. Absorption liquid scree was conducted according to type of gas turbine,and one low en ergy absorption liquid was selected. According to difference o recycle scale,three typical schemes were made,respectivel whole capture,capture quantity is 0. 5 t / h,and 1. 0 t / h,the economy and technology were conducted comparison,the resu showed that feasibility of scheme with capture quantity is 1. 0 t /is the best,its economy is the best,so it is the recommende scheme.
