Abstract
<PICT:0841636/III/1> In a method for the production of sulphur trioxide wherein sulphur dioxide and oxygen-containing gases are passed through a vertical series of perforated trays containing catalyst, heat exchangers are arranged after and between the catalyst trays, some of the heat exchangers constituting pre-heaters for the reaction gases which are passed internally therethrough on their way to the first catalyst tray, and through the other heat exchangers is passed a heat absorbing medium. A mixture of sulphur dioxide and oxygen-containing gases is fed from a conduit 26 through a heat exchanger 11, a conduit 28, a heat exchanger 9, a conduit 29, a heat exchanger 8, a conduit 30, a heat exchanger 7 and a conduit 31, to heat the gas mixture to a suitable temperature, which is controlled by shunting some of the gas past the heat exchangers via conduits 34 and 35 and portions 36 and 37 of conduits 30 and 31. The gases then pass down through catalyser units 1, 2, 3 and 4, comprising beds of catalyst on perforated plates, where the sulphur dioxide is partly oxidized to sulphur trioxide with evolution of heat which is removed by heat exchangers 7, 8 and 9. After catalyzer unit 4 the gases flow past a heat exchanger 12, through a catalyzer unit 5, and past a heat exchanger 13 and heat exchanger 11, and leave by an outlet 24. Steam is passed from a line 18 through heat exchangers 12 and 13, being controlled by valves 57 and 60, to absorb heat generated in catalyzer units 4 and 5, and super-heated steam is removed by a line 19. The operation is commenced by first blowing cold, dry air from a pump 44 through the catalyzer units and heat exchangers, then the circulating air is heated by means of steam in the heat exchangers 12 and 13, followed by heating the preheated air in an electrical heating device 48. Sulphur dioxide is then fed into the circulating heated air through a valve 20 to start the reaction, which is continued as above.
