Carbon capture and storage (CCS) works by trapping CO2 from the exhaust gases of fossil fuel power plants and then piping it to underground storage sites, such as disused oil wells.

而作为对比，如果利用碳捕捉与储存技术（CCS），在碳排放工厂进行碳捕捉然后将二氧化碳深埋在诸如废气油井一类的地方，每固定一吨碳需要成本达20-270美元。

The air exhaust pipe is sleeved on the air inlet pipe, so that the air inlet pipe is located in the center of the whole tank, so as to reduce piping space and reduce the volume of the whole device.

抽气管套在进气管上，使进气管位于整个罐体的中心位置，缩减了管排布空间，减小了整个装置的体积。
