Global cement emissions standards

Feb 21, 2014 Sulphur dioxide - Introduction. Airborne SO 2 reacts with water vapour to form sulphuric acid (H 2 SO 4).This contributes to acid rain, negatively affecting water sources, forests and crops. SO 2 is also a potent greenhouse gas.. SO 2 is emitted from cement plants via two main processes: 1. Sulphite impurities in the limestone and other raw materials; 2. ...

Among them, the direct leaching method includes the hydrosulfite method, sulfur dioxide method, ferrous sulfate method and so on. Taking the leaching method of sulfur dioxide for manganese as an example, the manganese ore is slurried, and sulfur dioxide gas is introduced, and the manganese oxide in the ore is converted into MnSO4 and MnS2O6.

Common Uses of Citric Acid In Food Cleaning amp Cosmetics

A process to remove sulphur dioxide from flue gases has been developed where citric acid is used as a scrubber, forming a complex ion which then reacts with H2S to give elemental sulphur regenerating citrate. This may become more important with increased environmental pressures. Citric acid esters of a range of alcohols are known, ...
