sulfur(IV) oxide

In this paper it is shown, that for cleaning the gas emissions with low consist of sulfur(IV) oxide it is advisable to use liquid-oxidative methods and use air oxygen as the oxidant. For the physico-chemical nature of the process the horizontal absorber with scoop- like dispersants are supposed to be the best. A principal flowsheet for purification of gases from sulfur(IV) oxide was proposed. Показано, що для очищення газових викидів з низьким вмістом сульфуру (ІV) оксиду доцільно застосовувати рідинно-окисні методи, а як окисник використати кисень повітря.

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.
