Abstract
<PICT:1014955/C1/1> Gases containing oxides of sulphur are desulphurized by contacting them, preferably between 350 DEG and 400 DEG C., with an adsorbent mixed with an iron oxide. Adsorbents specified are silica gel, aluminium oxides, clays, aluminium-magnesium oxides and activated carbon. The desulphurizing material may be formed by heating an adsorbent, previously impregnated with a solution of an iron salt, to convert the iron salt into an iron oxide. The exhausted desulphurizing material may be regenerated by thermal treatment, preferably at about 700 DEG C., and re-used, and the sulphur constituents thereby discharged may be collected. Any SO3 given off can be removed and dissolved to give sulphuric acid or sulphates. Fig. 1 shows the apparatus used in the desulphurizing of flue gases originating from an oilfired boiler. The boiler 1 contains the desulphurizing apparatus in its third flue 2. Flue gases pass through screening plate 4, covered with a layer of desulphurizing material 5. Any sulphur constituents not removed at 5 react with further fresh particles of desulphurizing material passing through perforated plates 7 and 8 as the gases flow through flue 2. The desulphurizing material is recovered in oven 12 and SO3 is removed through 13 and fixed as H2SO4 or sulphates. The regenerated desulphurizing material passes to cyclone 16, which also acts as a storage bin, wherein the particles are separated out and recycled. A modification is described in which the oven for regenerating the desulphurizing material is not used, the heat necessary for regeneration being taken directly from the boiler.
