Abstract: 23343-768 PROCESS FOR MAKING PHOSPHOROUS PENTOXIDE AND OPTIONALLY PHOSPHORIC ACID WITH UTILIZATION OF THE REACTION HEAT The disclosure relates to a process for making phosphorous pentoxide by subjecting elemental yellow phosphorus to combustion with dried air inside a steel-made combustion chamber with utilization of the reaction heat for the production of energy. To this end, the disclosure provides for the combustion to be effected inside a combustion chamber of which the walls are arranged so as to form a cooling system with cavities therein; for water or a water/steam-mixture as a heat carrier abstracting the reaction heat to be circulated through the cooling system, the water or water/steam-mixture assuming an increased temperature being circulated, preferably under increased pressure; for steam formed in the cooling system to be continuously taken therefrom; for an equivalent proportion of fresh desalted water to be introduced into the cooling system; for hot gaseous phosphorus pentoxide issuing from the combustion chamber to be condensed or worked up into phosphoric acid; for the steam taken from the cooling system to be passed through a steam delivery pipe disposed in the upper portion of the combustion chamber, or through a delivery conduit for product gas containing phosphorus pentoxide; for the steam to be heated therein to a temperature of 400 to 600.degree.C under constant pressure, and for the steam so superheated to be used.

Abstract: The invention relates to an apparatus for the production of phosphoric acid by subjecting yellow phosphorus to combustion inside a combustion tower, the apparatus comprising a cone-shaped shell with a flat bottom of acidproof material forming the combustion tower, the cone ratio of the shell being 1:10 to 1:12. An upwardly-directed off-gas outlet is secured to the lower portion of the shell and a plurality of downwardly directed spray nozzles is arranged so as to open through the middle portion of the shell into the interior of the combustion tower. An acid-receiving cup with an overflow weir is positioned near the upper end of the shell, the acid-receiving cup surrounding the combustion tower concentrically, being gas-tightly connected to, and supporting, a self-supporting cone-shaped tower cover having a passageway passed centrally through it. The overflow weir is formed of a tubular-annular structure disposed completely horizontally inside the acid-receiving cup. The tower cover forms, with respect to the horizontal, an angle alpha of at least 19 DEG . A water-cooled air inlet and a tubular holding means terminating in a phosphorus spray nozzle are hooked concentrically with respect to one another in, and are passed through the passageway in the cover.

Abstract: Liquid furnace slag, more particularly liquid phosphorus furnace slag, is transformed into granules. To this end, impinging contact between a free falling stream of liquid slag and a focused stream of water maintained under a pressure between 0.5 and 1.5 atmospheres gauge is produced so as to effect break-up of the slag into particles. The resulting particles are delivered to, and complete solidification thereof is effected in, a cooling zone having water therein.
