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.

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.

Direct Separation Liquid-Phase Hydration Technology for Heavy Soda Ash

2026-04-16 10:52:25

5

0

0

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.
