Direct separation of co _ ( 2 ) from flue gas will lead to a reduction of power generation efficiency and an increase of power generation cost. the content of co _ ( 2 ) in flue gas is only about 3 - 15 %, which will lead to complicated separation process and high cost. this is because co _ ( 2 ) separation is very difficult from common flue gas, which has low co _ ( 2 ) concentration and high n _ ( 2 ) concentration at normal pressure
從鍋爐排煙中分離co _ 2將在一定程度上使電站效率降低，發電成本增加，其主要原因是燃煤電站鍋爐排煙中co _ 2濃度一般僅為3 15 ，在較低的壓力下從以氮氣為主要成分的混合氣體中分離較低濃度的co _ 2氣體的難度很大，從而導致分離設備復雜，成本較高。 -
