多晶硅生產中還有大量的廢氣進行排放,其中不僅含有氯硅烷,還有大量的氫氣和氯化氫氣體,還原反應系統及多晶硅尾氣回收系統排放的富含非金屬雜質的氫氣、精餾裝置排放的尾氣基本上未進行回收利用,大量的氫氣和氯化氫氣體不能得到良好的回收,回收不徹底。一般采用堿液淋洗吸收后排放放空,環保問題較為突出,氯硅烷、氫氣和氯化氫損耗較大。

In the production of polycrystalline silicon, there is still a large amount of exhaust gas emitted, which not only contains chlorosilane, but also a large amount of hydrogen and hydrogen chloride gases. The hydrogen gas rich in non-metallic impurities emitted from the reduction reaction system and polycrystalline silicon tail gas recovery system, as well as the tail gas emitted from the distillation unit, are basically not recycled and reused. A large amount of hydrogen and hydrogen chloride gases cannot be well recovered, and the recovery is not thorough. Generally, alkaline solution is used for washing and absorption before discharging and emptying, which poses a prominent environmental issue. Chlorosilane, hydrogen gas, and hydrogen chloride suffer from significant losses.
Haohan Chromatography developed HH-1 capillary column for the determination of hydrogen chloride in polycrystalline silicon exhaust gas, with high column efficiency, good separation, and satisfactory results.
