Corrosion Problems in the Manufacture Of Phosphoric Acid From Elemental Phosphorus

Abstract The principal materials used in the construction of equipment for the manufacture of phosphoric acid (55-60 percent P2O5 ) from elemental phosphorus are described in this paper. This process involves the combustion of phosphorus to form P2O5 which is then reacted with water to form the acid. The general application of various metals, ceramics, and plastics in the construction of the processing equipment are discussed. The high temperatures characteristic of the process, as well as the impurities in the phosphorus burned, accelerate corrosion in parts of the system. Mist and impurities in the gas stream also cause some erosion. Methods of coping with these problems have been derived from large-scale tests and from plant operating experience. A highly concentrated phosphoric acid (containing 76 percent P2O5 ) also can be made in the regular equipment. The corrosion problems incurred in the production of this acid are discussed. Typical operating data are given for a phosphoric acid production unit....

Manufacture of Phosphoric Acid

IN the Chemiker-Zeitung of September 6, Dr. Carl Heinrich discusses at length the merits of the two main processes which are used for the manufacture of phosphoric acid from calcium phosphate. The essential features of these two processes, which may be conveniently termed the wet and dry processes, are set forth in textbooks of inorganic chemistry. In the wet process, the phosphate is decomposed by sulphuric acid, whereas in the dry process, silica replaces sulphuric acid and the furnace may be heated either externally or by means of an electric resistance. In view of the increasing importance of the product as a fertiliser, it is desirable that a more complete comparison of these two processes should be carried out.
