Capability Description

View Original

With over sixty years of deep expertise in the Solvay process for soda ash production, we have established a comprehensive process technology system covering the entire workflow from brine purification, carbonation crystallization, and filtration separation to calcination and packaging. We hold two invention patents and multiple utility model patents, along with several proprietary technologies recognized by industry associations, covering key processes such as carbonation, distillation, calcination, and filtration. Domestically, we have completed the design of numerous Solvay process soda ash projects, with single-unit design capacities ranging from 300,000 to 1,000,000 tons per year. Additionally, we have undertaken a 300,000-ton-per-year Solvay process soda ash project in the Middle East. Relevant projects have received first prizes for excellent engineering design and scientific and technological progress awards at the provincial and ministerial levels.

Deliverables for technology transfer include: a complete process package (containing material balance, heat balance, equipment list, and major equipment data sheets), basic design documents, operation manuals, and technical training. Customized technical solutions can be adjusted based on the owner's raw material conditions (rock salt, sea salt, lake salt) and product schemes.

Key Technologies for Integrated Production via Above-Ground and Below-Ground Circulation in Saline-Alkaline Calcium Wells

• Certification

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.
