Improvements in process for producing Phosphoric Acid by Wet process for the production of phosphate - calinos

摘要

Method for producing Phosphoric Acid by Wet process for the production of alkaline Phosphates.It consists in producing in the mouths of the first reactor optmizada feed concentration and total dispersion of sulfuric acid, forforico slurry and slurry pressure, introduced into the Reactor through coaxial Tubes on a Conical Diffuser placed above the level The porridgeWhich is at a temperature of 60 to 90 degrees Celsius and in constant agitation; she falls continuously calatravesando phosphate Powder slurry Turbulence caused by a Cyclone, producing a prewetting Dust with a Sieve of 100 Rushes on papill A, which is successive Reactors by decantation.In the latter of which is extracted and directs a dealer Cascade across a Band Filter, which is obtained by Separating suklfato Phosphoric acid calcium Dihydrate.
