| 摘 要： | 采用ＴＦ－ＴＡ工艺治理粘胶化纤厂废气。先以ＴＦ脱硫液选择脱除ＨＺＳ，再以ＴＡ液体脱除ＣＳ２。Ｈ２Ｓ脱除和再生能一步完成，脱除率９８％以上，其表达ηＨ２ｓ＝９９．５＋４．７１×１０－４ｘ－３．６８×１０－７ｘ２。ＣＳ２脱除率在气液比２００—３００时达８０％─９０％，其表达式：ηＣＳ２＝９８．９－１．３２×１０－３ｘ—２．００×１０－４ｘ２。文中还讨论了粘胶化纤厂废气总体治理意见。

| Abstract: | TF-TA process was developed for the treatment of gaseous sulfur compounds-containing wastes from a rayon production process. Thegaseous wastes were first contacted with a TFdesulfurizing liquor to remove H2S and thenpassed through a TA liquid to further remove CS2from them. The removal of H2S and the regeneration of TF desulfurizing liquor could be carriedout in a step. H2S was removed at a rate of over98% , and CS2 was removed at a rate of up to80% - 90% if there Was a gas/liquid ratio of 200- 300.The overall pollution abatement of wastegases emitted from a rayon manufactoring plantwas also discussed. |
