20140255287 | PRODUCTION OF PHOSPHORIC ACID BY A TWO-STAGE CRYSTALLIZATION PROCESS - A process and system for producing phosphoric acid. Phosphate rock is dissolved in phosphoric acid in a reaction vessel to form a slurry. The slurry is then reacted in a first stage of crystallization with sulfuric acid to produce calcium sulfate hemihydrate and phosphoric acid. The product acid is separated from the hemihydrates via filtration, and the filter cake is then reacted, in a second crystallization step, with additional sulfuric acid to produce dihydrate calcium sulfate (gypsum) and recovery solution. The gypsum is separated from the recovery solution via filtration and removed as a by-product. The recovery solution is recycled back to the transformation tank and to the hemihydrate filtration step. A feed acid tank combines wash solution, recovery solution and product acid.

20140051570 | PHOSPHATIC CLAY PRODUCTS FOR USE AS SOIL WETTING AGENTS, AND METHODS OF DELIVERY OF PHOSPHATIC CLAYS TO SOIL - Phosphatic clays, and the use of phosphatic clays as a soil wetting agent. Phosphatic clays as wetting agents aid in the retention of water in sandy soil, and/or for prevention or reduction of leaching of nutrients. Due to its unique particle size and shape, phosphatic clay exhibits high water absorbing and retaining qualities. Further, phosphatic clay is readily available as a by-product of mining of phosphatic ore. The phosphatic clay wetting agents increases the effectiveness of the water applied to the soil, thereby reducing the amount of run-off, and reducing the amount of water needed to accomplish sufficient irrigation. The phosphatic clay wetting agents can be delivered to the soil as a sprinkle-on product, spray-on product, soil amendment, fertilizer or seed coating, or fertilizer composition. | 02-20-2014 |
