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.

≤7 daysWashing Method for Refined Sea Salt to Produce Soda Ash Feedstock Salt Technology
2026-04-16 10:53:35
5
0
0
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.

Key Technologies for Integrated Production via Above-Ground and Below-Ground Circulation in Saline-Alkaline Calcium Wells
• Certification4
0
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.
