Abstract: <PICT:0780984/III/1> In removing sulphur compounds from boiler flue gases, hydrogen chloride is removed by washing the gases with a dilute solution of hydrochloric acid, before the sulphur compounds are removed by washing with a solution containing ammonium salts. Flue gases containing HCl and oxides of sulphur enter the first stage of a combined washer at 1 and are washed with dilute, e.g. 1.5 w/w, HCl circulated through sprays 2 by pumps 3.  The gases are further washed in the second stage with HCl of lower concentration circulated through sprays 4 by pump 5, while fresh water is added at 6, and the dilute acid passes through pipe 7 to the first stage, whence the acid may be withdrawn at 8 through filter 9. The gases then pass through spray catcher 10, whence drainings pass through 16 to the first stage, to grid packing 11, where oxides of sulphur are removed by washing with a solution of ammonium salts circulated by pump through pipe 13 and distributer 14, while ammonia liquor is added at 12.  The gases pass out through ducts 15 and solution, from which ammonium sulphate may be recovered, is withdrawn at 17.  In an alternative apparatus (not shown), separate single stage washers are used for the dilute HCl, and ammonium salt solution washing and it is stated that spray or grid packed washing towers may be used with co- or counter-current contact.  The HCl produced may be used to revivify ion exchange reagents.
