Purified Phosphoric Acid (Industrial/Food Grade) Technology

2026-04-16 09:37:53

7

0

0

Starting with wet-process phosphoric acid with a concentration of over 52%, industrial-grade phosphoric acid is obtained through an extraction and purification process. The raffinate acid generated during the process serves as a high-quality raw material for ammonium polyphosphate (APP). The integration of these two processes enables the extension of the phosphorus resource value chain. It should be noted that this technical route involves certain technical barriers (as indicated in technical archives). Specialized technical adaptation and development are required for wet-process phosphoric acid from different sources, and the client must accept a customized joint development model. The full suite of services covers the preparation of the process package, preliminary design, construction drawing design, as well as training and guidance during the commissioning phase, with a cycle of approximately 3 to 18 months. This solution is recommended for clients who already have wet-process phosphoric acid production capacity and wish to extend into downstream high-value-added products.

Monopotassium Phosphate (MKP) Extraction Technology

2026-04-16 09:33:27

10

0

0

Using wet phosphoric acid with a concentration of 26% to 40% as feedstock, high-purity monopotassium phosphate (MKP) is produced in a single step via a liquid-liquid extraction process. This simultaneously yields ammonium chloride potassium (which can be directly used as a compound fertilizer ingredient) and low-concentration raffinate phosphoric acid. The technology is patent-protected, and three industrial-scale units have already been constructed domestically (according to technical records), ensuring stable and reliable product quality. MKP is one of the fastest-growing premium varieties in the global water-soluble fertilizer market, with a terminal selling price significantly higher than that of ordinary phosphorus fertilizers. The comprehensive utilization of by-products further optimizes overall economic efficiency. A prerequisite for technology transfer is that the owner must possess a large-scale compound fertilizer production capacity to absorb the by-products. Deliverables include the process package, design drawings, operation manuals, training materials, and patent licensing documents, with a service cycle ranging from 3 to 18 months.
