Producing photovoltaic-grade electronic hydrofluoric acid using anhydrous hydrogen fluoride as the raw material through distillation technology. The technology is highly mature, with an industrial facility capable of producing 20,000 tons annually already built and stably supplying the market. The product directly serves the photovoltaic solar cell and semiconductor manufacturing industries, used for silicon wafer cleaning and surface treatment. As global photovoltaic installed capacity continues to rise, localized supply of photovoltaic-grade hydrofluoric acid has become a priority direction for industrial development in many countries. Due to extremely high product quality control requirements (ppb-level impurity control), the process commissioning cycle is longer than that of conventional projects, with a full-process service cycle of approximately 6 to 12 months.

A highly confidential process technology that uses fluosilicic acid, a by-product of wet-process phosphoric acid production, as the raw material to produce hydrofluoric acid via concentration with concentrated sulfuric acid. According to technical archives, this technology is classified as strictly confidential, with successful engineering projects currently existing only in China. Its strategic significance lies in converting waste fluorine resources from the phosphate chemical industry into high-value fluorine chemical products, achieving deep coupling of two industrial chains while reducing fluorine-containing exhaust emissions. The right to use the technology is authorized by the leading team, and the owner must accept preliminary targeted technology development. Services include process packages, engineering design, and production guidance, with support for customized joint technology development available; the project cycle ranges from 3 to 18 months.

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.

A highly flexible production process for phosphate fertilizers capable of utilizing various raw materials, including wet-process phosphoric acid, raffinate acid, liquid ammonia, or urea, to produce two product forms: solid ammonium polyphosphate for agricultural use and liquid ammonium polyphosphate. The process design fully leverages low-cost by-products as feedstock, significantly reducing production costs. This technology has a proven track record of successful export and implementation in Serbia (according to technical archives), validating the feasibility of cross-border technical cooperation. As a new generation of high-concentration, slow-release phosphate fertilizer, ammonium polyphosphate demonstrates fertilizer efficiency advantages in precision agriculture and facility agriculture scenarios that are difficult for traditional phosphate fertilizers to match. Services cover the preparation of process packages, basic and detailed design, and technical management during the commissioning phase, with a cycle of approximately 3 to 18 months.

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.

For phosphate ore resources with low grade or high impurity content, this technology employs a dihydrate process route to achieve the industrial production of wet-process phosphoric acid. Its core advantage lies in its broad adaptability to raw materials, enabling the processing of various grades and types of phosphate rock, thereby reducing reliance on high-quality ore sources. The process technology represents an advanced level in the industry, with a mature and reliable technical solution. The service model is consistent with the hemihydrate-dihydrate method, starting with the preparation of the process package, followed by basic engineering design and construction drawing design, and finally providing technical management support that includes personnel training and on-site guidance. All design documents and training materials are delivered concurrently with the project, with a standard cycle of 4 to 18 months. It is recommended that overseas owners intending to develop the phosphate chemical industry under local phosphate ore resource conditions prioritize the evaluation of this technical route.

A complete process technology for producing industrial phosphoric acid using high-grade phosphate rock as raw material and adopting the semi-hydrate-dihydrate route, developed by the team's own technical force. This technology has a high degree of maturity, and currently 9 industrial units of different scales have been built and operated domestically (according to technical archives). The complete service covers four stages: process package preparation (output of complete technical solution and process flow), basic engineering design (preliminary design), detailed engineering design (construction drawing design), and technical management services (including systematic training of operating personnel and on-site production guidance). The full deliverables include process package documents, process description and flow diagrams, preliminary and detailed design drawings, operation procedure manuals and training materials. Standard service cycle ranges from 4 to 18 months. For overseas markets with rich phosphate rock resources but relatively weak phosphate chemical industry foundation, this technology possesses strong adaptability and economic viability.
