- 在已建成“稀酸洗净化一转一吸”冶炼烟气制酸装置的基础上，通过增建熔硫焚硫系统，用低SO2冶炼烟气焚硫制酸，以改善装置的运行条件，年增产硫酸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.
