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 masstransfer 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.

Dissolved oxygen may be contained in the absorbing solution after the stage of its regeneration by air oxygen in line with reaction (3). Oxygen in the solution also causes an adverse reaction of the formation of sodium thiosulfate

The influence of Ferrum (II) sulfate (FeSO4) concentration in the absorbent solution and the influence of the process temperature on the efficiency of gas emissions purification in the apparatus with bucket dispersants was investigated. Кеуwordsexhaust gases, sulfur (IV) oxide.

The results of investigations of air oxygen chemisorption during regeneration of a quinhydrone absorbent solution in apparatus with a continuous barbotage layer are given. It is shown that the chemical reaction between chemisorbed O2 and quinhydrone catalyst reducing form is rapid and occurs in a liquid film. Researching results can be used for the choice of mass-exchange equipment for the process.
