Abstract: The sulfur-containing roasting gases of an ore-roasting plant are cooled in a waste-heat boiler, which produces steam, and then are subjected to particle removal in an electrostatic precipitator or cyclone. The gases are then scrubbed with recirculated aqueous sulfur acid and the gas is then passed through an electrostatic precipitator before being supplied to a plant for the contact process production of sulfur acid. According to the invention, the process is improved by condensing water from the gas in an indirect cooler between the scrubber and the final electrostatic precipitator while water or aqueous sulfur acid is sprayed into the gas upstream of the indirect gas cooler to augment the heat transfer from the gas to the cooled wall thereof.

Abstract: In a process for producing a fuel gas from a solid fuel by a gasification of solid fuel under a pressure of about 15-100 bars by a treatment with steam and a gas which contains free oxygen, cooling the raw gas to a temperature of about 150.degree.-200.degree.

C. in an amount of about 10-100 g per standard m.sup.3 of dry gas and has a CO:H.sub.2 O volume ratio of about 0.8-2, and subjecting the raw gas to a shift conversion, the improvement which comprises dividing the raw gas into first and second partial streams in a ratio of about 1:10 to 1:1, feeding the first partial stream with a surplus of water vapor to a first shift conversion stage at an inlet temperature of about 280.degree.-450.degree. C., and passing through a second shift conversion stage a mixture of effluent gas from the first shift conversion stage and at least part of the second partial stream of raw gas at a temperature of about 300.degree.-500.degree.

Abstract: A method of and apparatus for carrying out an exothermic process in which a combustible-containing solid (e.g. coal shale, pyrite or limestone in combination with fuel oil) are burned in a fluidized-bed reactor with primary and secondary streams of oxygen-containing combustion-sustaining gas (in a volume ratio of 1:20 to 2:1) supplied at different levels so that the primary gas acts as the fluidizing gas. The gas velocities and rate of gas feeds are controlled to provide a mean suspension density above the secondary gas inlet of 10 to 40 kg/m.sup.3. The major portion of solid feed is introduced into the space below the secondary gas inlet which is maintained substantially free of internal fixtures and the effluent gases are separated from the entrained solids which are recycled to the bed. Solids withdrawn from the bed are cooled in a fluidized-bed cooler and the temperature of the bed is maintained constant by the controlled recirculation of cooled solids thereto from the cooler. The gas heated in the cooler is fed to the bed as the secondary gas.

Abstract: Weighting material for a drilling fluid, e.g. a drilling mud, is produced by firing iron oxide solids, e.g. iron oxide ores, calcined pyritic ores or iron-oxide-containing products of other metallurgical processes, in a circulating fluidized bed or rotary furnace at a temperature of 1210.degree. C to 1400.degree. C in an oxidizing atmosphere in which the oxygen content is augmented to transform magnetitic components to oxides of lower magnetic susceptibility. The product is then cooled slowly at least until it reaches a temperature of 780.degree. C, also in an oxidizing atmosphere. The weighting materials have extremely low magnetic susceptibility and thus can be used without interfering with inductive monitoring of the position of the drill string.
