Title: Improvements in and relating to the recovery of sulphur oxides and ammonia
IPC: C01C1/02
Filed: 1964-10-23
Abstract: A process for the separate recovery of sulphur oxides and ammonia from the ammonium salts of sulphuric acid or from solutions of these salts in water and/or sulphuric acid comprises the conversion of free sulphuric acid and most of the combined sulphuric acid into SO2 by heating to 250-500 DEG  C. in the presence of reducing substances and the resultant mixture of ammonium sulphate/bisulphate is treated for the recovery of ammonia and sulphur oxides. The reducing substance may be present in the liquors as organic compounds, as with methacrylic ester waste liquors and may contain together with ammonium bisulphate, 10-50% by weight of free sulphuric acid and 0-20% by weight of organic substances and water.  The reducing agent may be added as H2, H2S, carbon, sulphite waste liquors, CO or hydrocarbons. If carbon in excess of the desired amount is present, sulphuric acid may be added or the organic substance removed by boiling or by heating to 250-490 DEG  C. to allow the required fraction of sulphate to react and removing the carbon excess.  In one aspect of the process the liquors are vaporized completely and then passed through a tube heated to 250-500 DEG  C. after the proportion of reducing substance has been adjusted so that the ammonia loss is as low as possible.

Abstract: 1325731 Electrolytic capacitors P R MALLORY & CO Inc 22 Sept 1970 [29 Sept 1969] 45138/70 Heading H1M The electrolyte in an electrolytic capacitor having a silver cathode comprises silver sulphate and a sulphate of vanadium, chromium, manganese and or iron dissolved in sulphuric acid solution. To prepare the electrolyte a high valency compound or complex of chromium, vanadium, manganese or iron which is at least partly soluble in sulphuric acid solution is added to the acid and in the presence of a silver cathode reacts to give the metal sulphate and silver sulphate. Preferably sufficient silver sulphate is formed to give a saturated solution with a reserve of undissolved salt. Some metal oxide may also be formed. The device may be heated to accelerate the reaction. Suitable compounds are potassium permanganate, ferric sulphate and chromic sulphate, or duplex salts e.g. ferric chromate, dichromate or vanadate, or silver permanganate, chromate or vanadate. These compounds, in addition to providing silver sulphate, are stated to etch and clean the cathode and contribute to the double layer at the cathode arising from the silver-silver sulphate interaction. The double layer causes high cathode capacitance so that the overall capacitance is close to that of the anode. Production of hydrogen at the cathode is minimized and the capacitance is stated to be stable over long periods. The silver cathode may have a coating of powdered platinum or graphite.
