Recently, the China Petroleum and Chemical Industry Federation organized the 2025 Petroleum and Chemical Industry Energy and Water Conservation Experience Exchange and Technology Promotion Conference, and released the list of 2024 benchmark enterprises for energy efficiency "leaders" and water efficiency "leaders" of key products in the petroleum and chemical industry. Tangshan Sanyou Group Soda Ash Company has won the title of energy efficiency "leader" benchmark for 14 consecutive years and water efficiency "leader" benchmark for 5 consecutive years.

It is understood that relying on regional resource advantages, Tangshan Sanyou Group Soda Ash Company has built a dual water-saving system integrating concentrated seawater utilization and sewage recycling. By introducing by-product concentrated seawater from surrounding enterprises, constructing a full-coverage sewage and rainwater recycling system, and applying alkali residue waste liquid resource utilization technology, the company has realized intensive, economical and recycled use of fresh water. In terms of energy conservation, the company focuses on core processes, efficiently recovers waste heat resources, and uses waste such as carbide slag slurry as alternative raw materials. Driven by digital transformation, the intelligent control system for lime kilns developed by the company has effectively stabilized production conditions, reduced raw material consumption, and gradually realized full-process intelligent control of key processes such as light ash production, evaporation and absorption, and carbonization, significantly improving production accuracy and stability. By establishing a refined management system involving full staff participation and whole-process control, the company decomposes and quantifies green development goals at all levels with assessment mechanisms, converging strong synergy for green development.
