Principals for the Creation of Effective and Economically Sound Treating Processes of Industrial Emissions with Sulfur Oxide Low Content

In the present work the sulfur cycle in nature is analyzed. The role of sulfur(IV) oxide, sources and volumes of its production, the dynamics of emissions and forecast for the future have been described. The main part (more than 80 %) of emissions are poor waste gases (<0.5 SO2), which are treated with great difficulties. Economically sound and technologically simple methods for gases treating, as well as equipment mostly corresponding to the physico-chemical essence of the processes limiting the general intensity of treating have been suggested.

Hydrolytic Sulphate Acid Evaporation by Waste Gases from Burning Furnaces of Meta-Titanic Acid Paste

The advisability of hydrolytic sulphate acid evaporation by waste gases from burning furnaces of meta-titanic acid paste has been theoretically grounded and practically proved. The optimum regime of the evaporation process has been determined and mass-transfer apparatus has been designed. The high intensity of the process has been confirmed by experiments. The dependence of the motive force and waste gases moisture on the heat transfer factor has been determined.
