Phosphoric acid

liquid

Ballestra is a Prayon Technology permanent licensee since 2009. Offered processes are based on both Di-Hydrate (DH) and Hemi-Hydrate (HH) gypsum formation and different combinations of the two processes, to be selected according to several factors as rock quality, required acid concentration, water availability, steam consumption. Features of the proposed solutions All available process allows the production of 52-54% Phosphoric Acid, after a concentration step. The phosphoric acid is mainly used as feedstock component in the fertilizers production plants. Plant efficiency High efficiency in the conversion of phosphates and in the control of the phosphate, granted by the adoption of Best Available Technology together with Prayon process design, minimizing the risk of plant packing and extending plant availability. Plant emissions Air pollution control, by means of a dedicated scrubber, to comply with plant emissions level required by the most stringent laws and standards. Well proven know-how in selecting the most suitable materials of construction to grant acid resistance. By-products The plant configurations allow the recovery of fluosilicic acid (FSA) as process by-product, with concentration up to 18%. The FSA can be sold as such to the market, or further transformed into valuable AHF (Anhydrous Hydrofluoric Acid) or AlF3 (DBI collaborates with Buss ChemTech for such technology) or neutralized for disposal. Tailor made configuration Ballestra Phosphoric Acid plants are highly customizable to process several types of phosphate rocks and maximize the plant efficiency.
