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.

Providing expert-level technical services in the field of chemical safety, including: support for current safety condition assessments, review of safety facility designs, HAZOP analysis, and safety training. The team possesses extensive practical experience in compiling dedicated chapters for safety facility designs and is well-versed in the safety regulatory framework and technical standards of the chemical industry.

Short-term on-site safety expert services are available for chemical enterprises to assist with safety production permit reviews, hazard identification, and rectification efforts. Training content can cover specialized topics such as chemical process safety, hazardous chemical storage and transportation safety, and fire safety.

"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 company maintains leading comprehensive engineering design capabilities in the soda ash industry in China. It has completed over 60 large-scale soda ash projects, with plant capacities ranging from 80,000 to 1.2 million tons/year. Design capabilities cover all three major process routes—ammonia-soda process, linked soda process, and natural soda ash process—as well as derivative products including sodium bicarbonate, food-grade ammonium chloride, and dense soda ash. The company possesses overseas design delivery experience from three soda ash projects in Iran (200,000 tons + 200,000 tons + 80,000 tons renovation). Multiple soda ash engineering projects have received national and provincial-level excellent design awards. The company provides full-stage services from project proposal and feasibility study to preliminary design and construction drawing design, and can extend to technical support during the commissioning phase.

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.
