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.

A national invention patent technology. The filtered mother liquor from the Solvay process for soda ash production contains a large amount of calcium chloride, which is traditionally discharged as waste liquid. This patented technology efficiently extracts calcium chloride solution from the filtered mother liquor through a specific process, addressing the environmental pressure of waste liquid treatment while achieving resource utilization of by-products. It opens up new profit growth points for soda ash enterprises using the Solvay process.

Suitable for the construction of calcium chloride production facilities by soda ash enterprises using the Solvay process.

Producing food-grade or industrial-grade baking soda (sodium bicarbonate) from soda ash mother liquor or refined sodium carbonate solution via a carbonation crystallization process. We hold a utility model patent for a "Carbonation Tower without a Cooling Section for Baking Soda Production." The optimized structural design of this tower improves gas-liquid contact efficiency and crystallization conditions, enhancing the particle size uniformity and yield of the baking soda product.

We have completed engineering designs for multiple baking soda projects domestically, with individual capacities ranging from 30,000 to 200,000 tons per year. Recently, we also participated in the design of a new project integrating CO₂ capture with baking soda co-production. Deliverables include the baking soda process package and data sheets for key equipment.

The Φ2500～Φ3000 specification external return caustic soda steam calcination furnace is the core equipment in the calcination process of soda ash production and has been recognized by the industry association as proprietary technology. This calcination furnace adopts indirect steam heating to decompose sodium bicarbonate (heavy alkali) into finished soda ash products, featuring high thermal efficiency, stable product quality, and reliable operation. The relevant technical achievements were awarded the first prize of provincial scientific and technological progress in the early stages.

We provide supporting design data packages for the calcination furnace, equipment processing drawings, installation guidance, and commissioning services. Different specifications can be customized according to production capacity requirements.

The ammonia-soda process for soda ash production generates large volumes of distillation waste liquid containing calcium chloride, posing a long-standing environmental challenge for the industry. Addressing this critical issue, several proprietary technologies recognized by industry associations have been developed, including underground cavity injection technology for waste slurry, waste slurry mixing technology, and comprehensive waste liquid treatment technology. These solutions cover the complete technical chain from waste liquid pretreatment and solid-liquid separation to final disposal.

These technologies have been successfully applied and verified in waste liquid treatment projects at multiple large-scale soda ash enterprises domestically, with related projects receiving provincial-level science and technology progress awards. Tailored technical solutions can be provided based on the client's specific conditions, including geological factors, emission standards, and site constraints. Deliverables include the waste liquid treatment process package, basic design, and operation manuals.

Proprietary technology certified by industry associations. The soda ash production process imposes strict quality requirements on raw salt; however, sea salt, due to its high impurity content, is typically difficult to use directly. This technology employs a multi-stage washing and refining process to cost-effectively convert sea salt into raw salt (washed salt) that meets the requirements for soda ash production. This enables coastal soda ash enterprises to eliminate their dependence on rock salt, significantly reducing raw material transportation costs.

Core process stages include brine preparation, multi-stage counter-current washing, dewatering, and drying. Deliverables include the process package and basic design documents. This solution is suitable for coastal chemical enterprises that possess sea salt resources but lack access to rock salt supplies.

Proprietary technology certified by industry associations. Traditional production of heavy soda ash typically employs dry or wet hydration processes, which involve lengthy workflows and high energy consumption. This technology utilizes a direct separation liquid-phase hydration route, integrating the hydration conversion of light soda ash and solid-liquid separation into a single step. This simplifies the process flow, reduces steam consumption, and lowers equipment investment. The resulting heavy soda ash products feature high bulk density and low dust content, meeting the quality requirements of high-end users such as float glass manufacturers.

Suitable for adding heavy soda ash production lines to existing soda ash facilities or for technical selection in the heavy soda ash production processes of new projects.

"A proprietary technology certified by the industry association, addressing the recovery challenge of heavy soda filter mother liquor in soda ash production. This technology employs a vacuum distillation process route to achieve efficient separation and recovery of ammonia and carbon dioxide from the mother liquor at relatively lower temperatures. Compared with traditional atmospheric distillation, this technology significantly reduces steam consumption, improves distillation efficiency, while simultaneously mitigating equipment corrosion and scaling issues.

This technology is applicable to energy-saving transformation of the distillation process in ammonia-soda process soda ash enterprises, and can also serve as the preferred solution for new soda ash plant distillation systems. Deliverables include the proprietary technology process package, key equipment selection guidance, and on-site调试 support."

The combined soda ash process co-produces soda ash and ammonium chloride, featuring high utilization rates of raw salt and zero solid waste discharge, making it one of the mainstream soda manufacturing processes in China. Decades of engineering practice have been accumulated in this technical direction, completing the design of multiple combined soda projects with capacities ranging from 450,000 to 1.2 million tons per year, covering various types such as new construction, expansion, and relocation renovation. Related projects have repeatedly won national and provincial-level awards for excellent engineering design.

Core technical highlights include optimization of the carbonation system, improvement of mother liquor circulation efficiency, and enhancement of ammonium chloride drying and granulation processes. The transfer content covers the complete process technology package, basic design, operating procedures, and personnel training, suitable for enterprises with synthetic ammonia facilities or conditions for purchasing liquid ammonia.
