Title: Improvements in recovery of sulphur
IPC: C01B17/06
Filed: 1935-09-28
Abstract: <PICT:0463685/III/1> Sulphur is obtained by oxidizing iron sulphide at temperatures above 1000 DEG  C. to form iron oxide and sulphur dioxide which is reduced by passage through a porous bed of carbonaceous material at a temperature substantially the same as the temperature of production so that no heat is supplied to maintain the reducing reaction except that contained in the sulphur dioxide.  In the arrangement shown, iron sulphide is oxidized in molten baths 10, 11 and 12 by means of air blown in through tuy<\>geres 38, 40 and 41 at temperatures above 1000 DEG  C. and preferably above 1200 DEG  C. Preferably the operation of the three baths is staggered to ensure a uniform substantially oxygen-free gaseous product, or they may be connected in series to permit the gaseous product from a nearly exhausted charge to be passed through a bath of higher sulphur content.  The gases are then passed via conduit 31 and tuy<\>geres 52 through a bed of coke in chamber 13 at temperatures not below 1000 DEG  C., so that the coke is maintained incandescent without external heat or air.  A rotary kiln may be used, if desired.  The sulphur-containing gases are then passed through a heat-exchanger 14 where the air for the oxidizing operation is preheated, through a dust-collector 15, then through a water-cooled condenser 16 maintained at 115 to 150 DEG  C., and finally through an electrical precipitator 79.  In a modification, the iron sulphide is oxidized in the form of a fine suspension, and a dust collector is interposed between the oxidation furnace and the reduction furnace to remove iron oxide dust.  Specification 364,351 is referred to.
