Title: Improvements in and relating to the removal of oxides of sulphur from flue gases
IPC: B01D53/50
Filed: 1954-04-09
Abstract: <PICT:0805531/III/1> Oxides of sulphur are removed from flue gases by treating the gases with an aqueous solution of ammonium salts to which ammonia is added at a rate corresponding to the absorption of oxides of sulphur, wherein the treatment is carried out in two or more stages in the first of which the flue gases are scrubbed with a concentrated solution of ammonium salts, i.e. approximately 7 mols. total ammonia per litre, whilst in successive stages progressively more dilute solutions are used as scrubbing media, the concentration of ammonium salts in the final stage being not more than one-tenth, and preferably, not more than one-twentieth, of the concentration in the first stage, and the solution in the final stage containing ammonium sulphate and only traces of sulphites.  The resulting solution contains ammonium sulphate, bisulphite, and sulphite, and is subsequently evaporated to recover ammonium sulphate, or heated under pressure in an autoclave in the presence of sulphuric acid to convert the dissolved salt into ammonium sulphate and sulphur.  The gas enters lower compartment 1 of the two compartment scrubbing tower at 4 and passes countercurrent to the concentrated scrubbing solution circulated by pump 5 and distributed by 6 on to grid packing 7.  The gases leave by pipe 8, by-passing partition 3, into upper compartment 2 and pass countercurrent to dilute scrubbing solution circulated by pump 9 and distributed on to grid packing 11.  The gases then pass through spray eliminator 12 to the chimney.  Ammonia liquor is added through 13 to the solution in the lower compartment, and the concentration is kept constant by running solution off at 14 and replacing by solution from the upper compartment through 15.  The solution in the upper compartment is made up by water added at 16. As shown, the concentration of ammonia in the upper compartment is maintained by ammonia entrained in the gas from the lower compartment, but ammonia liquor may also be added to the upper compartment solution.  More than two stages may be used and the stages need not be arranged above one another.  Sprays alone can be used for distribution.  Specification 633,627 is referred to.

Abstract: 1,098,989. EHD generators. A. M. MARKS. March 11, 1966 [March 11, 1965], No. 10825/66. Heading H2A. In an EHD generator employing a charged aerosol, the droplet-size is increased to that giving optimum mobility, by including a condensable vapour in the working gas, this vapour condensing on the droplets to increase their size, and they then pass through the working area. The droplets may be formed by the direct spraying of liquid from fine jets in the presence of an electric field which further disrupts each droplet, or by spraying a condensable vapour through a jet such that its expansion causes cooling and, therefore, condensation. As shown, superheated vapour 23 is sprayed from holes 22 in tubes 30 into the gas-stream 15. Droplets 44 are formed, and these pass through a region of charging electrodes 17 maintained at 3 kV. The charged droplets are collected at points or wires 34 at a higher potential. The droplets which emerge at 22, grow by condensation from the vapour from the same jet 22. If desired, (Fig. 4, not shown) an additional array of jets of liquid may be situated downstream of the tubes 30. A 'scavenger' additive may be employed.
