An industrialized application technology that has won the Second Prize of the Provincial Science and Technology Progress Award. This technology deeply couples underground salt mine extraction with soda ash production, achieving integrated above-ground and underground cyclic production of salt, alkali, and calcium. Waste liquid from soda ash manufacturing is injected into underground solution cavities for salt mining, while the extracted brine serves as raw material for soda ash production, forming a closed-loop cycle. This technical route fundamentally resolves the environmental bottleneck of waste liquid discharge in the ammonia-soda process while significantly improving the utilization rate of rock salt resources.

It has been successfully implemented in large-scale domestic projects for the comprehensive utilization of rock salt resources. The related engineering design has received First Prizes for Excellent Engineering Design at both provincial and municipal levels. This technology is suitable for soda ash production enterprises possessing rock salt mineral resources.

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.

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.

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.
