摘要:

摘要:以杭州某电厂390MW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0.5t/h和捕集量为1.0t/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1.0t/h的方案具有可行性,且经济性最佳,故为推荐方案。

Abstract:

Abstract:With 390MW gas steam combined cycle units of one power plant in Hangzhou as object,the paper studied feasibility of increasing device of carbon capture.Absorption liquid screen was conducted according to type of gas turbine,and one low energy absorption liquid was selected. According to difference of recycle scale,three typical schemes were made, respectively whole capture, capture quantity is 0.5t/h, and 1.0t/h,then economy and technology were conducted comparison, the result showed that feasibility of scheme with capture quantity is 1.0t/h is the best,its economy is the best,so it is the recommended scheme.
