Yet while this sort of chemical recipe was already shown in the 90s to work with a pure gas, the sort of emissions that come from a fossil fuel power station are typically full of impurities.

然而，尽管这种'纯'气体方式的化学处理方案在上世纪90年代已经问世，但化石燃料电厂排放出的废气通常杂质很多。

Power-station exhaust can thus be purged of its CO2 by running it through an amine bath before it is vented, and the amine can be warmed to release the gas where it will do no harm.

这样，可以使电厂产生的废气在排放前通过胺液，分离出其中的二氧化碳；之后在适当的地方加热胺液就可以释放二氧化碳。
