燃燒后捕獲（PCC）是指從化石燃燒產(chǎn)生的煙氣中分離出CO2。 空氣中的燃料——煤、天然氣或石油。在以煤為基礎的電力的情況下，如圖1-1所示，煤是 在空氣中燃燒，釋放的熱量通過(guò)與蒸汽驅動(dòng)的渦輪機相連接被轉換成電力。 發(fā)電機。燃燒產(chǎn)生由N2、CO2、H2O、O2和主要 諸如SOx、NOx和重金屬等化合物。其中一些使用現有方法刪除 選擇性催化還原(SCR)、靜電沉淀(ESP)和煙氣等技術(shù) 脫硫。PCC工藝則旨在選擇性地將CO2從剩余氣體混合物中分離出來(lái)。 如圖2-1所示。捕獲之后，CO2可以被壓縮并儲存在地下，用于其他一些地方 諸如提高石油采收率（EOR）或用于某些其它產(chǎn)能而不導致 排放到大氣中。

Post-combustion capture (PCC) refers to the separation of CO2 from flue gas derived from combusting fossil fuels – coal, natural gas, or oil – in air. In the case of coal-based power, as shown in Figure 1-1, coal is combusted in air and the liberated heat is converted to electricity by steam-driven turbines connected to generators. The combustion results in a flue gas mixture consisting of N2, CO2, H2O, O2, and a host of compounds such as SOx, NOx, and heavy metals amongst others. Some of these are removed using existing technologies such as selective catalytic reduction (SCR), electrostatic precipitation (ESP), and flue-gas desulphurization (FGD). A PCC process then aims to selectively separate CO2 from the remaining gas mixture as shown in Figure 2-1. After capture, CO2 can be compressed and stored underground, used in some other processes such as enhanced oil recovery (EOR), or used in some other capacity that does not result in its emission into the atmosphere.
