pilot plant testing succeeded in producing all kinds of phosphate and compound fertilizers, mainly dap and map. with the cix technology, the process can provide flexibility to produce merchant grade acid matching any industrial uses. the produced merchant grade phosphoric acid is characterized by the lowest suspended solids, no post
novaphos was founded in 2008 as jdcphosphate by dr. joseph megy to develop his vision for a solid-phase carbo-thermal reduction technology for making phosphoric acid efficiently. since that time, we have been focused on making our technology work: in the lab, in pilot operations and in our demonstration plant.
feb 02, 1998 of the process is a weak phosphoric acid solution. however, the phosphoric acid is defluorinated and has less metal impurities then the phosphoric acid from the conventional phosphoric acid production process. one-tenth scale pilot plant was built in 1997 to collect design and process information on the
the mathematical model used in this work represents a 1016 kgh capacity pilot plant used to produce phosphoric acid by the di-hydrate process. the pilot plant consists of three isothermal cstrs and one filterfeed tank all connected
pilot-plant process is described that purifies wet-process phosphoric acid for the production of a high-quality urea-ammonium polyphosphate base solution. An intermediate product, crystalline urea phosphate, is produced from urea and merchant-grade wet-process phosphoric acid.
phosphoric acid launch of engineering studies for the construction of a pilot plant for the recovery of sulphur from phosphogypsum launch of the project to build a pilot plant for the production of green ammonia, in collaboration with the fraunhofer institute and the gep
by controlling pH and reducing conditions, the uranium could be precipitated from the phosphoric acid. after an economic evaluation of the process, a pilot plant was constructed to further test and refine the process. meanwhile, laboratory investigations continued on another possible method of precipitating the uranium from the phosphoric acid.
