摘要： The disclosure relates to a process for removing foreign components, especially zinc, from the product cycle during the production of yellow phosphorus inside and electrothermal furnace. To this end, the disclosure provides for molten ferrophosphorus and a calcium metasilicate slag and also a dust-containing gas mixture consisting essentially of carbon monoxide and phosphorus in vapor form to be taken from the furnace charged with phosphate pellets, coke and gravel. After electrostatic separation of the dust from the gas mixture, the dust is water-treated and made into a dust suspension. Crude phosphate is granulated on a granulating means using a mixture of dust suspension and binder which preferably is a clay suspension. The granulated material is calcined on a sintering device and made into phosphate pellets. A portion of the molten slag taken from the electrothermal furnace is allowed to solidify and the solidified slag is ground. The ground slag and at least a portion of dust suspension are granulated on a granulating means. The granulated slag and dust suspension are dried. It is possible for the dried granulated matter to be ground once again, to be granulated once again together with a further portion of dust suspension, and to be dried again. The dried and granulated matter is ultimately calcined and made into pellets.

摘要： Phosphorus is recovered from the phosphorus sludge formed in the electrothermal production of phosphorus by contacting the sludge with a hydrophobic surface with sufficient force to cause the droplets of phosphorus in the sludge to coalesce and accumulate on the surface, from which it can become detached in the form of large phosphorus drops. One such recovery process involves contacting the sludge, under hydrostatic or other pressure, with a porous membrane formed of a hydrophobic material, through which passes coalesced phosphorus from the sludge, the water and the bulk of the impurities of the sludge being restrained against passage. Other coalescing procedures involve shearing the sludge between sliding hydrophobic surfaces and passing the sludge between hydrophobic surfaces in rolling contact. Typical hydrophobic materials are polyethylene, polypropylene, and rubber.

摘要： A process for producing phosphorus pentoxide from phosphate ores in a rotary-type kiln includes heating, by exposure to a flame, a porous bed comprising phosphate ore and solid carbonaceous material to a temperature sufficient to reduce the phosphorus pentoxide to phosphorus vapor. The phosphorus vapor is oxidized in an oxidation zone disposed over the porous bed to heat the porous bed. An inert gas is used to purge the porous bed of carbon monoxide formed during the reduction reaction to drive the reduction reaction more rapidly toward complete reduction of the phosphorus pentoxide and to inhibit oxidation of the phosphorus vapor and carbonaceous material within the porous bed.

摘要： The process of this invention provides for reducing the tendency of a carbon monoxide gas stream, containing a minor level of elemental phosphorus, to corrode metallic surfaces in a combustion zone upon combustion of the gas stream in the combustion zone to combustion gases. The process comprises, prior to combustion:(a) cooling the gas stream to a sufficiently low temperature to condense a quantity of elemental phosphorus to produce a reduced level of elemental phsophorus in the gas stream; and(b) diluting the gas stream with an effective amount of combustible gas, wherein the effective amount of combustible gas is an amount which is effective in producing a dew point of the combustion gases, with respect to the quantity of acid, e.g. meta-phsophoric acid (HPO.sub.3), produced by the combustion of the reduced level of elemental phosphorus, less than the temperature of the metallic surfaces.
