最后，炼油厂排放很多的气体，如二氧化硫(SO2)、二氧化氮(NO2)、二氧化碳、一氧化碳、甲烷、双环氧乙烷、氟化氢、氯、苯和其他气体。

Finally, refineries emit many gases like sulphur dioxide (SO2), nitrogen oxide (NO2), carbon dioxide, carbon monoxide, methane, dioxins, hydrogen fluoride, chlorine, benzene and others.

近年来，大气酸雨问题日益严重，造成酸雨的主要原因是大气中二氧化硫、氟化氢等有毒气体含量的增加。

Recent years, the harm of acid rain is growing, mainly due to the increase of SO2, HF and other toxic gases of the air.
