- 在已建成“稀酸洗凈化一轉一吸”冶煉煙氣制酸裝置的基礎上，通過(guò)增建熔硫焚硫系統，用低SO2冶煉煙氣焚硫制酸，以改善裝置的運行條件，年增產(chǎn)硫酸20kt。Abstract Operation condition was improved and 20kt/a of additional production capacity was obtained in an existing low SO 2 smelter offgas sulphuric acid plant with weak acid scrubbing and single absorption process by adding a sulphur melting and burning system and blowing in the burner with the smelter offgas instead of air to produce sulphuric acid.
